Permanent Packing List
Documents & Admin — Kept in Trailer
These never leave the RV. Keep physical copies in a labeled folder in the glove box or a dedicated document pouch.
Safety Gear — Non-Negotiable
Check these monthly. CO is odorless. A failing propane detector has killed people. This gear costs less than one campsite.
Electronics
Kitchen
Bedding
Bathroom Staples
Tools & Maintenance
Trailer-Specific Spares. These items cost almost nothing and make the difference between a minor inconvenience and a ruined trip. The trailer lug wrench is the most critical — the lug nut size on most trailer wheels is different from the tow vehicle. The wrench in your truck won't fit.
Power Tools Worth Packing. These items seem like overkill until you need them. The impact driver alone saves you from a miserable roadside tire change in 90°F heat. The leaf blower prevents hundreds of dollars in slide seal damage in 2 minutes.
Emergency Gear
The 3am Problem. Full black tank. Campground bathrooms closed. Dump station 10 miles away. Happens to every RV owner eventually. The $25 emergency toilet pays for itself the first time you need it.
Hookup Gear — Always in the Trailer
These stay permanently. You'll need them at every campsite. Never leave home without them.
Outdoor Living
Kids' Gear — Permanent in Trailer
Food — Permanent Pantry Staples
Restock after every trip. These should always be in the trailer so you're never starting from zero.
Week of Trip Prep
Time-staged beats one big list. Most departure-day disasters were a T-2 task nobody did. Work through this week by week — the earlier tasks are confirmations and research; the later tasks are physical checks and loading.
T-7 — One Week Out: Confirm & Plan
T-3 — Three Days Out: Food & Supplies
T-2 — Two Days Out: Trailer Pre-Check
Do these checks 2 days out, not the morning of. If the battery is dead or the propane tank is empty, you have time to fix it. On departure morning, you don't.
T-1 — Day Before: Load & Home Prep
Starting the fridge 4–8 hours before departure is not optional. An RV absorption refrigerator takes that long to reach temperature. Packing warm food into a warm fridge is how you get sick on day 2.
T-1 — Evening: Pack In-Vehicle Items
These ride in the tow vehicle, not the trailer. You'll need them during the drive — don't bury them.
Clothing & Personal Gear
Pack per person, per trip. These don't live in the trailer.
Personal Care & Health
Kids' Trip Gear
Trip Documents
Bring these — they don't live in the trailer.
Hitch & Go Safety
Run this checklist every single trip. Most trailer failures happen in the first few miles because a step was skipped. This sequence is in the correct order. Do not skip ahead.
Step 1 — Tow Vehicle Checks
Seasonal service is separate. Oil changes, brake inspections, and transmission fluid are before-the-season tasks, not pre-trip checks. For the actual pre-trip items, proceed below.
Step 2 — Safety Devices Check
Do This Before Every Trip. These devices save lives. None take more than 30 seconds to check. Make it a habit.
Step 3 — Hitching Sequence (Do in This Exact Order)
Safety Chain Rule. Chains must cross in an X-pattern so they cradle the coupler if it separates. Too long = drag on pavement. Too short = bind when turning. Correct: a J-curve when hitched, just clearing the ground.
Step 4 — Weight Distribution & Sway Control
Backing Up with WD Bars. If you need to do significant backing or tight maneuvering at the campsite, remove the WD bars first. They limit your turning radius and can bind during tight turns. You can re-equip them after you're parked.
Why It Matters. Too little tongue weight causes dangerous trailer sway. Too much overloads your tow vehicle's rear axle. The safe zone for single-axle trailers is 10–15% of total trailer weight on the tongue. How you load the interior matters just as much: roughly 60% of cargo weight should sit in front of the axle and 40% behind — this directly affects tongue weight and how the trailer handles on the road.
Step 5 — 7-Pin Connector & Lights
Step 6 — Trailer Tire & Wheel Checks
Check the Trailer Sticker, Not the Sidewall. Trailer tire pressure is often different from your tow vehicle's. The correct spec is on a sticker inside your trailer's door frame — not on the tire sidewall.
50-Mile Re-Torque Rule. After any wheel removal — new tires, rotation, tire change, bearing service — lug nuts must be re-torqued at 50 miles and again at 100 miles. They settle and back off after initial torque. This is the #1 cause of trailer wheel separation and is entirely preventable.
Step 7 — Trailer Interior & Exterior
⚠ TV Antenna — Check Every Single Trip. The most common cause of costly overhead clearance damage. A highway overpass or drive-through clearance bar will shear it off and potentially peel back your roof.
⚠ Pets in the Trailer. NEVER travel with pets inside the trailer while towing. No climate control, temperatures can exceed 130°F in summer, carbon monoxide risk from exhaust, and they're trapped if something goes wrong. All pets ride in the tow vehicle with you.
Step 8 — Final Pre-Departure
The 1/4-Mile Stop. This is the single most important step beginners skip. Drive 1/4 mile, pull over safely, walk around the trailer. Loose lug nuts, lights that stopped working, chains that shifted — this stop catches all of it.
Campsite Arrival & Setup
Do steps in order. Hooking up water before leveling, or extending slides before checking clearance, are among the most common first-trip mistakes.
Step 0 — Back Into Your Site
Backing a trailer is a learned skill — not intuition. The most common campground incident is a backing collision. The most common reason is skipping the spotter or using improvised hand signals. Use the protocol below every time.
First-Timer Tip. Request a pull-through site for your first few trips — no backing required. You can practice backing skills once you've mastered the setup sequence.
Step 2 — Level Side-to-Side (While Still Hitched)
Why First. Leveling must happen before you unhitch, before hookups, before slideouts. An unlevel trailer means the fridge won't cool properly, doors won't stay open or closed, and sleep is uncomfortable.
Step 3 — Chock Wheels (Before Unhitching)
Step 4 — Unhitch from Tow Vehicle
Step 5 — Front-to-Back Level (Tongue Jack)
Why This Step Is Separate. Front-to-back leveling can only be done after unhitching because the hitch controls tongue height while attached. Adjust the tongue jack now, not before.
Step 6 — Stabilizer Jacks
Step 7 — Shore Power
EMS Surge Protector — Non-Negotiable. Campground power is notoriously unreliable. Faulty pedestals can send voltage spikes that fry every appliance in your trailer. The EMS protects everything. Never plug in without it.
Step 8 — Water Hookup
Step 9 — Sewer Hookup (Full Hookup Sites Only)
⚠ Never Leave Black Valve Open. Leaving the black tank valve open lets liquids drain continuously but leaves solids behind. They dry out and create a "poop pyramid" that requires professional service to remove. Always dump black when 2/3 full.
Step 10 — Slideouts & Awning
Step 11 — Interior Setup
RV Solar & Power Setup
There are two ways to add solar power to a trailer. The first is dead simple: buy a power station and a portable panel, plug them together, and you're done. The second is a permanent wired system — more capacity, more customization, more involved. This guide covers both. Most people should start with Path 1.
Know Your Power Needs First
Before buying anything, get a rough sense of how much power you actually use. Everything else flows from this number.
A realistic weekend estimate. A typical trailer with LED lights, phone and laptop charging, and a 12V compressor fridge uses roughly 800–1,200 Wh per day. Broken down: the fridge is the biggest draw at 400–600 Wh/day (it cycles on and off — it's not running constantly). Lights and devices add another 200–400 Wh. That's it for most weekend trips.
| Device | Typical Daily Use |
|---|---|
| 12V compressor fridge | 400–600 Wh |
| LED lighting (whole trailer) | 40–80 Wh |
| Phone charging (2 phones) | 20–30 Wh |
| Laptop | 150–250 Wh |
| 12V fan | 80–160 Wh |
| CPAP (no heat, with DC adapter) | 60–100 Wh |
| Air conditioner | Not solar-viable — needs shore power or a generator |
A 1,000Wh power station covers a typical no-fridge weekend comfortably. Add a 12V fridge and you want 1,500–2,000Wh to get through two days without recharging.
Path 1 — Power Station Setup
No wiring. No installation. Plug in a panel, plug in your devices, go. A portable power station is a battery, inverter, and charge controller all in one unit. This is the right starting point for most trailer owners — and for many people, it's all they'll ever need.
The Essentials Setup
Good for: weekend camping, devices + lighting, no 12V fridge.
What the panel actually puts back. On a decent day — figure 4–5 hours of real sun — the 200W panel returns roughly 500–700Wh to the station. That's more than enough to cover a full day of no-fridge use and keep the C1000 topped off trip after trip. Cloudy days cut that significantly; plan on the station's stored capacity carrying you through overcast stretches.
The Extended Setup
Good for: longer trips, a 12V fridge running full-time, or powering more.
Why two panels for the extended setup. The C2000 has the capacity to run serious loads — but solar only pays off if the panels can keep up with what you're using. With a 12V fridge cycling all day, one 300W panel is supplementing; two panels are actually replacing what you're burning. The second panel is the same unit, plugged in parallel — no extra gear required.
Around-Camp Companion
Quick Win: Upgrade Your 12V Battery to Lithium
You don't need solar to get more out of your trailer's battery. If your trailer has an existing 12V system, swapping the stock AGM battery for a LiFePO4 battery is one of the highest-impact upgrades you can make — more usable capacity, lighter weight, and it lasts 3–4x longer.
Standard AGM batteries give you about 50% of their rated capacity before damage. A 100Ah AGM = 50Ah usable. A 100Ah LiFePO4 = 80–100Ah usable. That's a significant difference before you've added a single solar panel.
Path 2 — Wired System
For more capacity, a permanent install, or a system you can keep expanding. A wired system has four main components. You don't need to understand all of them deeply — you need to understand what each one does so you can buy the right size and have a conversation with the person installing it.
The Four Components
Solar Panels collect sunlight and convert it to DC electricity. Size is measured in watts. More watts = faster recharging. Portable panels work; rooftop panels are more efficient since they can angle to the sun at all times.
Charge Controller sits between your panels and battery bank. It manages the charging process and protects your batteries from overcharging. Always buy MPPT — it recovers 15–30% more power than cheaper PWM controllers. Size it to handle your total panel wattage.
Batteries store the power your panels collect. This is the most important part of the system and where it's worth spending real money. LiFePO4 (lithium) is the right choice for anyone building new — more usable capacity, longer life, lighter weight than AGM.
Inverter converts 12V battery power to standard 120V AC for wall-plug devices. You only need one if you're running AC-powered devices off the battery bank. Always buy pure sine wave — modified sine wave inverters damage sensitive electronics.
On Installation
The wiring is where people get into trouble. Undersized wire is a fire hazard. A poorly fused system can start a fire. If you're not confident with 12V electrical work, hire an RV tech or mobile installer to do the battery and wiring connections. The component costs are where you save money — not the labor on safety-critical connections.
A professional install on a basic system (panels, controller, one battery, inverter) typically runs $200–400 in labor. It's worth it.
Remote Work Setup
The two things that make or break remote work on the road. 1. Reliable internet that isn't campground WiFi. 2. Enough power to run your setup. Get these two right first. Everything else is comfort.
Internet — Pick Your Setup
Connectivity Checklist
Power — Know Your Numbers
Quick Power Math. Laptop: 45–95W. Hotspot: 10–20W. Starlink Mini: ~30W. Ring light: 15–40W. Total typical work setup: 100–185W. A 1000Wh power station runs that for 5–8 hours without recharging.
Video Call Setup
Why This Matters. RV interiors are dark and echoey. Without a proper setup, you look and sound unprofessional on every call. These four items fix the problem completely.
Ergonomics — The Problem No One Talks About
The Dinette Problem. The RV dinette is your default workspace. The bench seating will give you lower back pain within 2 hours. This is not dramatic — it's physics. Fix it before your first work trip.
Schedule & Communication
Connectivity Backup Plan
Campsite Teardown
Step 1 — Before You Start Breaking Camp
Checkout Protocol. If the campground requires checkout at the office or via a posted procedure, do it now before you start breaking down — not at the last minute with a fully hitched rig you can't easily move. Know the checkout time, know if there's a penalty for being late, and know whether you need a receipt or confirmation.
Step 2 — Secure the Interior
Interior First. Secure everything inside before you start disconnecting outside. Once you start hitching up, you'll be moving and can't keep running back in.
Step 3 — Slides & Awning Prep (Critical Order)
Leaf Blower Step. Before retracting any slide, spend 2 minutes with a leaf blower on the slide roof. Pine needles, leaves, and dirt on top of the slide get dragged into the seal and mechanism when retracted. This is the single most preventable source of slide seal damage.
Step 4 — Waste & Utilities Disconnect
Dump Before You Drive. If you're more than 2/3 full on black or gray, dump before leaving. See the Tank Dump Procedure for full instructions.
Step 5 — Hitch Up
Use the Hitch & Go Safety list for the full hitch sequence. The most common departure mistakes: wheel chocks not removed, tongue jack not fully retracted, breakaway cable not connected.
Step 6 — Final Site Walk (Leave No Trace)
Walk the Full Site — Twice. First pass: collect everything yours. Second pass: verify the site is clean for the next camper. Most often left behind: camping chairs, door mats, kids' toys under the trailer, items behind fire ring, and cord adapters at the pedestal.
Step 7 — Pre-Departure Safety Check
Stand at the back of the trailer and do one full visual pass. You're looking for anything moving, hanging, or not where it should be.
Monthly & Annual Maintenance
A trailer has no dashboard warning lights, no odometer-linked service reminders, and no computer monitoring its condition. Everything that goes wrong starts as a slow, preventable failure — and the only early-warning system is you doing this checklist.
Section 1 — Every Month (Between Trips)
Section 2 — Every 6 Months (Start and End of Season)
Section 3 — Annually (Spring Startup)
The annual tasks are the expensive ones to skip. A blown wheel bearing costs $3,000+ roadside. A delaminated wall costs $5,000+. A cracked roof leak costs $8,000+. The annual checklist is prevention, not maintenance.
Section 4 — If You Go More Than 30 Days Without Using the Trailer
These are not full inspection items — they're the minimum checks required before returning to service after a storage gap. Storage degrades things faster than use does.
Tank Dump Procedure
The only rule that matters. Always dump black tank before gray tank. Gray water acts as a final rinse through your sewer hose. Reverse the order and your hose stays dirty.
Tank Level Reference Guide
| Level | Action |
|---|---|
| Black < 1/2 full | Wait if possible — a fuller tank dumps more effectively |
| Black 2/3 full | Standard dump point |
| Black full | Dump immediately; do not add more waste |
| Gray < 1/2 full | Wait; gray dumps quickly regardless of level |
| Gray 2/3–full | Dump alongside black tank |
Before You Drive to the Dump Station
Tank Monitor Reality Check. Most built-in monitors read wrong after a few uses — sensors get coated and read "full" when they're not. Use the monitor as a rough guide. When in doubt, dump if you've been there 2–3 days.
Step 1 — Gear Up
Step 2 — Connect to Sewer
Slope Matters. Hose must run downhill from trailer to dump inlet with no sags. Sags trap solids and cause backup, odors, and clogs.
Step 3 — Dump Black Tank First
The Clear Elbow Is Worth $8. You can't see through an opaque sewer hose. The clear 45° elbow shows you exactly when the black tank is empty and when flush water runs clean. Always in the kit.
Step 4 — Dump Gray Tank Second
Why Gray Goes Second. Gray water from your sinks and shower is relatively clean compared to black tank waste. Running it last sends a final rinse through the entire sewer hose before you disconnect.
Step 5 — Disconnect & Rinse
Step 6 — Treat & Refill Black Tank
Always Leave Treatment in the Tank. Empty tanks = odors. Enzymatic treatment needs water to activate and coat the tank walls. Don't leave the black tank completely dry — always add treatment + a gallon of water.
Step 7 — Clean Up
When Things Go Wrong
Dump Station Etiquette
Winterization
⚠ Strong Recommendation: Have a Professional Do This
How to use this list even if a pro does the work. Read through before your service appointment. It tells you every step that should be completed, what supplies the tech is using, and what to ask about when you pick up your trailer.
Supplies — Order 2–3 Weeks Before Your Appointment
Step 1 — Dump & Flush All Tanks First (30–45 min)
Do This Before Everything Else. Never winterize with full or partial tanks. Follow the Tank Dump Procedure in full, then add a double dose of black tank enzyme treatment.
Step 2 — Drain the Fresh Water System (20–30 min)
Water Heater Bypass — Saves 2 Gallons. Before adding antifreeze, engage water heater bypass valves to isolate the heater from the plumbing circuit. If not already installed, add the Camco bypass kit ($10–20).
Step 3 — Add Antifreeze to Plumbing (30–45 min)
⚠ Pink RV Antifreeze Only. Never use automotive antifreeze (ethylene glycol) — it is toxic and will contaminate your water lines. RV antifreeze is propylene glycol. It looks pink. Anything else is wrong.
Step 3A — Pump Method (Recommended for DIY)
Step 3B — Blow-Out Method (Alternative — Requires Air Compressor)
The blow-out method pushes water out of lines with compressed air instead of replacing it with antifreeze. No antifreeze taste in spring, but P-traps still need antifreeze added manually. If you don't own a compressor, the pump method is easier.
Step 4 — Battery & Electrical (15 min)
Battery Left Uncharged in Winter = Permanent Damage. A 12V lead-acid battery left discharged in freezing temps suffers permanent capacity loss in as little as one winter. A $30 smart maintainer pays for itself in avoided replacements.
LiFePO4 Cold-Weather Warning. Standard LiFePO4 batteries cannot accept a charge below 32°F. Charging a frozen lithium battery causes permanent internal damage. If you store in freezing temperatures, either remove the battery or use a model with a built-in heating element. Discharging below freezing is fine; charging is not.
Step 5 — Exterior Inspection & Seals (30–45 min)
80% of RV Water Damage Enters Through Failed Seals. Five minutes of lap sealant in the fall prevents thousands in delamination and mold remediation in the spring. Walk the entire roof and every seam.
Step 6 — Tires, Wheels & Security (15 min)
Tires Develop Flat Spots After 30 Days Stationary. Place trailer on leveling blocks or tire cradles for storage longer than 30 days. Move the trailer a few inches every month if possible.
Step 7 — Pest & Moisture Prevention (15–20 min)
Mice Will Find Your Trailer. A stored trailer is a perfect winter home for rodents. They enter through gaps as small as a dime and nest in insulation, chew wiring, and destroy soft goods. Skip this step once and you may spend 8 hours cleaning in spring.
Step 8 — Final Lockdown (10 min)
Storage Location Notes
- Indoor heated storage: Antifreeze is still recommended; the water heater drain and P-trap protection matter regardless. Skip tire covers and exterior wax.
- Indoor unheated storage: Full winterization required. Tire covers less critical indoors.
- Covered outdoor storage: Full winterization, tire covers recommended.
- Uncovered outdoor storage: Full winterization plus a fitted RV cover — use a proper RV-specific cover, not a tarp. Tarps trap moisture and abrade the finish.
Spring Startup & De-Winterization
⏱ Plan this for the day before your first trip, not the morning of. The water sanitation soak takes 4–8 hours unattended. Start early, let it soak through the day, flush in the evening. First trip the next day.
Supplies to Have on Hand
Step 1 — Exterior & Interior Inspection (30 min)
Step 2 — Battery & Systems Restart (15 min)
Step 3 — Flush Antifreeze from Water System (30 min)
⚠ Flush All Antifreeze Before Sanitizing. Antifreeze and bleach together can produce chlorine gas. Flush antifreeze out completely before adding any bleach solution. Don't rush this step.
Step 4 — Water Heater: Drain, Anode Rod, Refill (30 min)
Anode Rod: Inspect Every Spring — Replace Every 1–3 Years:. The anode rod is a sacrificial magnesium rod that corrodes so your water heater tank doesn't. When it's 50% gone or the steel core wire is exposed, replace it now. Cost: $10–18.
Suburban vs. Atwood/Dometic
Suburban water heaters use a sacrificial magnesium anode rod that corrodes so the tank doesn't. Atwood and Dometic water heaters use an aluminum-clad tank with no anode rod — if you have one of those, skip the anode steps and simply drain and flush. Check your water heater brand on the exterior access panel before proceeding.
Step 5 — Bleach Sanitation: Fresh Water System (20 min active + 4–8 hr soak)
Bleach Formula. Use PLAIN unscented household bleach (sodium hypochlorite, 6–8.25%). Ratio:¼ cup of bleach per 15 gallons of tank capacity.Always pre-dilute in a gallon of water before adding to tank — never pour bleach directly in.
⏱ Soak: 4–8 Hours Minimum — Overnight Is Better. Let the bleach solution sit in the full system for at least 4 hours. Do not use any water during the soak. Set a timer and walk away.
Formula reminder
¼ cup of plain unscented household bleach per 15 gallons of fresh tank capacity. Pre-dilute in 1 gallon of water. Never pour undiluted bleach directly into the tank.
Step 6 — Flush Bleach & Rinse (30–45 min, possibly next morning)
Expect 2–3 Full Tank Flushes to Clear the Bleach. The water must smell and taste neutral before it is safe to drink.
Step 7 — Final Spring Startup Checks (15 min)
Fresh Water System Sanitation
Run this procedure at least every 6 months. Also run it any time you notice an off smell or taste in your water, after purchasing a used trailer, after using a questionable water source, or after the trailer sits unused for 2+ months.
⏱ Most of the time is the bleach soak (4–8 hours unattended). Start in the morning, soak all day, flush in the evening.
Supplies
Step 1 — Prep (10 min)
Step 2 — Mix & Add Bleach Solution (10 min)
The Formula. ¼ cup of plain bleach per 15 gallons of fresh tank capacity. Pre-dilute in 1 gallon of water before adding to tank. Never pour undiluted bleach directly in. Examples: 30-gal tank = ½ cup bleach · 45-gal = ¾ cup · 60-gal = 1 cup
Step 3 — Distribute Through System (15 min)
⏱ Soak: 4–8 Hours Minimum. Leave the bleach in the system for at least 4 hours. Overnight (8–12 hours) is better. Do not use any water during the soak. Set a reminder and walk away.
Step 4 — Flush & Rinse (30–45 min)
Clear the Bleach Fully Before Drinking. You may need 2–3 full tank flushes. The water is not ready to drink until it smells and tastes completely neutral.
Step 5 — Finish (10 min)
Troubleshooting
Eggy or Sulfur Smell — But Only in Hot Water? Your water heater anode rod is the culprit, not the tank. Replace the rod (see Spring Startup Step 4 for full procedure) — the smell typically clears within 1–2 uses.
Pre-Purchase Inspection
A professional inspection costs $200–$400 and is worth every penny. But if you're standing in a seller's driveway — or just want to know what the inspector is looking at — this is the exact walkthrough they run. Work through it in order. Give yourself at least 90 minutes. Rushing this is how people buy someone else's problem.
Section 0 — Document Check (Before You Touch Anything)
Do this first. A trailer with title issues, an active lien, or open NHTSA recalls is a problem you inherit the moment you sign. Check these before you drive anywhere.
Before You Go — Tools to Bring
You don't need much. These will catch 90% of issues a casual eye misses:
Schedule on a sunny day
Natural light makes water stains, delamination, and roof cracks dramatically easier to spot.
Section 1 — First Impressions & Exterior
Walk the entire rig slowly before touching anything. You're looking for the story the trailer tells before anyone starts selling it to you.
⚠ Dealbreaker Watch
Bubbling or rippled sidewalls are delamination — water has already gotten between the skin and the frame. Small patches can be repaired; large sections across a whole wall cannot be economically fixed.
Section 2 — Frame, Axle & Running Gear
Get low. This is where the most expensive surprises hide.
⚠ Dealbreaker Watch
A bent frame or cracked welds at structural points are walk-away conditions. These are not repairable to original spec.
Section 3 — Tires & Wheels
Trailer tires fail more often than people expect — and almost always at highway speed.
Why Age Beats Looks
A trailer tire can look nearly new and still fail from UV and ozone degradation. Age is the real number — always check the DOT date. Sellers often don't know it and buyers almost never ask.
Section 4 — Roof & Seams
More RV damage comes from the roof than anywhere else. Water damage always starts here.
⚠ Dealbreaker Watch
Any soft spot on the roof means water has already penetrated the decking. If it's soft in one place, check directly below it inside — you'll almost certainly find staining or rot.
Section 5 — Interior: Floor, Walls & Ceiling
Water damage is the most expensive thing you can inherit. Every soft spot or stain has a history.
The Smell Test
Before you look at anything, close the door, stand quietly, and take a breath. Mustiness, mold, or a sharp ammonia smell (rodents) are flags worth paying attention to. You can fix a lot of things — you cannot fully un-mold a trailer.
Section 5b — Slide-Out Leak Test (If Equipped)
This test is only possible if the seller allows it and you have a water source. It's worth asking for. Slide-out seal failures are the second most common water intrusion point after the roof, and they often don't show on a dry-day inspection.
Section 6 — Plumbing & Water System
Winter Bypass Confirmation
Ask the seller if the trailer was properly winterized each year. A single season of burst pipes can mean hidden plumbing damage throughout the rig. Signs: water stains with no obvious source, low pressure at specific fixtures.
Section 7 — Electrical System
⚠ Dealbreaker Watch
Any signs of DIY electrical work — exposed splices, wire nuts, mixed wire gauges — should make you nervous. RV electrical fires are real and usually start at a bad connection.
Section 8 — Propane & Appliances
Why Test Both Modes on the Fridge
RV absorption refrigerators can fail in one mode while working fine in the other. A fridge that runs on electric but won't light on propane — or vice versa — is a repair job. Replacement absorption fridges are expensive.
Section 9 — Hitch & Tow Connection
Section 10 — Test Drive (If Possible)
Ask to hitch it to your tow vehicle and drive it. Even a 1-mile loop in a parking lot tells you things a static inspection cannot. Many sellers will agree to this; it's a reasonable request for a $15,000–$50,000 purchase.
Final Walk — Dealbreaker Summary
Run through this before you decide. These are the conditions that justify walking away or negotiating hard:
The Offer Rule
Every item that's wrong is a negotiating point, not a dealbreaker by itself. Get two things: a written list of everything you found, and a rough repair estimate. Then decide if the asking price — minus those repairs — is still a fair deal.
Towing Weights & Trailer Loading
Tongue weight and overloading are the leading cause of catastrophic trailer accidents on American highways. Not blowouts. Not brake failures. Weight. Owners drive away from dealerships every day with setups that exceed their tow vehicle's payload, their trailer's GVWR, or both — because nobody at the dealer sits down and walks through the numbers with them. This checklist does that. Work through it once, record your numbers, and keep them in the trailer.
Section 1 — The Numbers You Need to Know
GVWR — Gross Vehicle Weight Rating
The maximum allowable total weight of the loaded trailer: structure, cargo, water, everything. It is stamped on the door sticker inside your trailer's entry door. You may not exceed it legally or safely. It is not a suggestion.
GAWR — Gross Axle Weight Rating
The maximum weight each axle is rated to carry. Also on the trailer door sticker. On single-axle trailers, one overloaded axle means the entire trailer is overloaded. On tandem-axle trailers, uneven loading can push one axle over its GAWR even if the total trailer weight is within GVWR.
UVW — Unloaded Vehicle Weight
The trailer's weight as it left the factory — no cargo, no passengers, no water except what's permanently installed. This is the manufacturer's baseline. It is almost always optimistic. Actual UVW after dealer-installed options is usually higher.
CCC — Cargo Carrying Capacity
GVWR minus UVW. This is every pound of cargo, water, food, gear, and personal items you are legally permitted to add. On midsize trailers it is commonly only 1,000–1,500 lbs — a number that disappears fast when you add a full fresh water tank (332 lbs at 40 gallons), bikes, tools, and a week of provisions.
Tongue Weight
The downward force the trailer coupler exerts on the tow vehicle's hitch ball. Should be 10–15% of your total loaded trailer weight — not GVWR, the actual weight the trailer is at when hitched. Too little tongue weight causes trailer sway. Too much overloads the tow vehicle's rear axle and causes the front wheels to lighten, reducing steering control.
GCWR — Gross Combined Weight Rating
The maximum combined weight of the tow vehicle and the loaded trailer together. Found in the tow vehicle's owner's manual — not the brochure, not the dealer's estimate, the manual. GCWR is the first limit exceeded by many setups that otherwise appear within spec.
Tow Vehicle Payload
How much the tow vehicle can carry — including passengers in every seat, cargo in the bed, and the tongue weight pressing down on the hitch. Found on the tow vehicle's door sticker. Full-size trucks commonly rate 1,500–2,000 lbs of payload. Add two adults, two kids, gear in the back seat, and 700 lbs of tongue weight and you may already be there before a single item goes into the bed.
Section 2 — Where To Find Your Numbers
Section 3 — The Tongue Weight Rule
Tongue weight must be 10–15% of your total loaded trailer weight. Not GVWR — the actual weight of the trailer as it sits when you're ready to leave. The distinction matters because most trailers travel loaded well under GVWR.
- For a 7,000-lb loaded trailer: correct tongue weight = 700–1,050 lbs
- Too little (under 10%): the trailer is too light at the coupler; at highway speed, small disturbances become sway events that amplify into jackknife or rollover
- Too much (over 15%): the rear of the tow vehicle squats, the front axle lightens, steering feels vague and slow to respond
Measure it, don't guess. A Sherline 2000-lb tongue weight scale or a WeighSafe ball mount with built-in scale tells you whether you're in the safe zone. The 10–15% rule is theoretical until you measure.
Section 4 — How to Load Your Trailer
How cargo is distributed inside the trailer directly determines tongue weight. This is the variable you control every single trip.
Section 5 — How to Actually Weigh Your Setup
Guessing doesn't work. The only honest weight is one measured on a certified scale with the rig loaded exactly as it will be for travel.
The CAT Scale is the only honest weigh. Your estimate of what everything weighs is almost always wrong. Professional RV inspectors find overloaded setups on 60–70% of the trailers they examine. Drive to the scale before your first trip, not after something goes wrong.
Section 6 — Common Overloading Mistakes
These are the situations where owners unknowingly tip over the line:
- Full fresh water tank at departure. Many owners fill the tank before leaving and travel on full. That's up to 332 lbs added to the trailer's weight — usually behind or near the axle, reducing tongue weight while simultaneously consuming a large portion of CCC.
- Bikes or cargo carriers on the rear. Weight mounted behind the trailer axle reduces tongue weight. A pair of bikes on a rear hitch carrier can shift tongue weight below the 10% threshold on a loaded midsize trailer.
- Costco run on the way out of town. Cases of water, food, and supplies added to the rear of the truck bed consume tow vehicle payload and shift weight off the tow vehicle's front axle.
- Forgetting passengers. A family of four adds 600–800 lbs to the tow vehicle before anything goes in the bed. That counts directly against tow vehicle payload — the same budget that includes tongue weight.
Emergency & Roadside Procedures
Most RV guides cover how to hook up, how to level, and how to use the dump station. Very few cover what to do when a tire blows at 65 mph, or when the trailer starts swaying and the driver panics and brakes. Those are the moments where the wrong decision happens in two seconds and ends the trip — or worse. Read this guide before you need it. Walk through each scenario mentally so the correct response is already there when your hands are on the wheel.
Section 1 — Pre-Emergency: The Kit
None of the procedures in this guide work without the right tools in the right place. These items belong in the trailer or tow vehicle at all times — not in the garage, not on the maybe-I'll-grab-it list.
Section 2 — Trailer Tire Blowout at Speed
The instinct is wrong. When a trailer tire blows, the instinct is to brake hard and steer to correct the swerve. Both reactions increase the likelihood of a rollover. The rig goes where physics sends it for the first few seconds — fighting that motion is what causes the loss of control.
Do this instead, in order:
After stopping:
Section 3 — Trailer Sway Event
Trailer sway is a resonance problem. A trailer that begins to oscillate side to side tends to amplify its own motion. The tow vehicle gets pushed by the trailer, not the other way around. At sufficient amplitude the tow vehicle can roll. The correct response is the opposite of what panic demands.
Do this instead, in order:
After stopping:
If you don't have a brake controller override, or the trailer has no brakes
hold the steering wheel straight, ease fully off the gas, and do not touch the brake pedal until the sway decreases. Steer with the minimum input necessary to track the lane. This is why trailer brakes are not optional on any trailer over 1,500 lbs loaded.
Section 4 — Breakaway Switch Deployment
The breakaway switch activates if the trailer separates from the tow vehicle. It uses battery power to run the trailer's brakes until the battery is depleted. This is the correct outcome — a separated trailer on a highway stops instead of continuing downhill or into traffic. The breakaway battery exists for exactly this event.
Section 5 — Hub Overheating
Bearing failure is the most common cause of roadside wheel separation on travel trailers. Trailer wheel bearings have no monitoring system — no dashboard warning, no sensor. The only check available to you is a hand temperature test at rest stops and fuel stops.
At every 1/4-mile stop and at rest stops
touch the center of each hub with the back of your hand, not your palm. If a hub is hot enough to cause a palm burn, you will pull back instinctively from the back-of-hand contact first. All hubs should feel equally warm to moderately warm after driving. One hub significantly hotter than the rest is a bearing problem in progress.
Section 6 — Roadside Tire Change (Single-Axle)
This is doable, but only with the right tools. The tow vehicle's scissor jack is not rated for trailer weight and must not be used under the trailer. The tow vehicle's lug wrench almost certainly will not fit trailer lug nuts. Confirm both before your first trip, not during a blowout on I-90.
Section 7 — Smell of Burning
Burning smells while towing cover a range of causes from minor to stop-immediately. The smell's character and location tells you which.
Burning rubber from behind the tow vehicle, after heavy braking: tow vehicle brake heat — pull over and allow brakes to cool with the vehicle stationary and in park; do not set the parking brake while brakes are hot; continue cautiously once the smell clears.
Sweet or syrupy burning from under the tow vehicle's hood: engine coolant burning off a hot surface from a leak — stop the engine immediately; do not run an overheating engine; check the coolant level only after the engine has cooled; call roadside assistance if the coolant is low or the source of the leak is not obvious.
Sharp acrid electrical burning smell: 12V wiring overheating somewhere in the tow vehicle or trailer — pull over and check all exterior bays and the interior for smoke; check the 7-pin connector at the hitch; disconnect shore power if you're at a site; trace the source before continuing.
Burning smell from the trailer interior or bays that does not clear while driving: stop and investigate; do not drive a trailer that is burning; what begins as a wiring fault can become a structure fire within minutes while moving.
Roadside assistance coverage. Confirm before any trip whether your policy covers the trailer separately from the tow vehicle. AAA's standard and Plus memberships do not cover RV trailer roadside service — you need the RV-tier membership. Coach-Net and Good Sam Roadside Assistance cover both the tow vehicle and the trailer by default. Verify your specific policy terms before you leave, not from the shoulder of a highway.
Boondocking & Dry Camping
Boondocking is a different operating mode, not just camping without hookups. Most issues people have with their first dry camping trip come from treating it like a campground with the power and water turned off. It's not. It requires a different pre-trip checklist, different daily discipline, and a different mindset about resources. Run this checklist before your first trip and review the daily habits every time you go.
Before You Leave — Research and Legal Prep
Pre-Trip Trailer Prep
Water Conservation — Daily Practice
The math is simple. A standard travel trailer fresh tank is 30–45 gallons. A family of four using a full campground hookup mindset will empty it in 1.5 days. A family of four using dry camping discipline can make the same tank last 4–6 days. The difference is entirely behavioral.
Power Management — Daily Budget
Know your draw before you drain your bank. A 100–200Ah lithium battery bank sounds like a lot until the refrigerator, furnace fan, water pump, and phone charging have been running for 18 hours. Know what your trailer draws and budget accordingly.

First 30 Days of Ownership
The dealer lot is not the place to learn your trailer. Dealership walkthroughs are 30 minutes on a good day. This checklist is the actual orientation — done at home, under control, before your first real trip.
Week 1 — Document Everything
Week 2 — Test Every System at Home
Do this in your driveway with shore power and a water hookup. The goal is to fail here, at home, not at a campground 3 hours away.
Week 3 — First Overnight (In the Driveway)
Your first night in the trailer should be in your driveway. All utilities, full systems, full family. The things you'll discover: that the fridge doesn't cool in propane mode, that a drain line drips, that the awning motor makes a noise, that you don't know where the breaker is. Discover them here.
Week 4 — First Short Trip (Under 30 Miles from Home)
Your first real trip should be close enough to drive home if something goes wrong. One night, full hookups, within 30 miles. The goal is to run everything at a real campsite under real conditions — not to have a great trip.
