What First-Time RV Buyers Need to Know
Buying a used RV can save you thousands compared to a brand-new model, but only if you know what to look for. A thorough RV inspection checklist will help you avoid hidden problems, negotiate a fair price, and feel confident in your purchase.
This guide covers everything you need to inspect before buying a used RV, whether it’s a motorhome, travel trailer, or fifth wheel.
Why an RV Inspection Matters
Purchasing an RV is a big investment. Without a proper inspection, you risk buying an RV with hidden water damage, electrical issues, or worn-out appliances. By following this used RV inspection checklist, you’ll:
- Identify costly repair issues before buying
- Ensure the RV is roadworthy and safe
- Protect yourself from overpaying
- Gain peace of mind with your investment

First Impressions: Exterior Inspection Checklist
Start by walking around the entire RV slowly. Take in the big picture, and do not rush this step.
✅ Roof & Seals – Check for cracks, soft spots, or leaks around vents and A/C units. Learn how to spot issues with this RV roof maintenance guide from Camping World.
✅ Sidewalls & Paint – Look for delamination, bubbling, or fading.
✅ Windows & Doors – Inspect seals, locks, and latches for water intrusion.
✅ Undercarriage & Frame – Check for rust, cracks, or weld issues.
✅ Tires & Axles – Verify tire age using the DOT code, check tread depth, and confirm suspension condition.Pro Tip: Bring a flashlight and inspect underneath the RV for rust, frame damage, or signs of leaks.
Interior Inspection Checklist
✅ Floors & Ceilings – Step firmly to find soft spots that may indicate water damage.
✅ Walls & Cabinets – Look for discoloration, mold, or delamination.
✅ Windows & Seals – Test for smooth opening/closing and leaks.
✅ Bathroom & Plumbing – Run faucets, flush toilets, and check for leaks. The RV Travel Plumbing Guide has additional tips.
✅ Appliances – Test refrigerator, stove, furnace, A/C, and water heater.Mechanical & Electrical Systems
✅ Engine & Transmission (for motorhomes) – Check fluids, belts, and service records.
✅ Generator – Test under load and review maintenance logs.
✅ Battery Bank – Verify voltage, age, and clean connections.
✅ Electrical System – Inspect breaker panel, outlets, and lights. See FMCA’s RV Electrical Basics for troubleshooting.
✅ Propane System – Inspect for leaks and ensure regulators function properly.Electrical & Power Systems
Power systems are a must-check before buying. Do not just assume the lights work.
- Test batteries (both house and engine if motorized)
- Plug into shore power and make sure it connects properly
- Turn on lights, outlets, fans, and appliances
- Operate all slide-outs
- Run the generator and inverter (if installed)
Tip: Ask about recent upgrades to solar or lithium systems—they are a big plus!
Plumbing: Water Systems & Leaks
Water damage is one of the most expensive problems with used RVs. Be thorough.
- Run all faucets, shower, and toilet
- Look under sinks and around plumbing for leaks
- Test the water pump and water heater
- Smell and inspect tanks (fresh, grey, black)
- Feel the floor near the bathroom and kitchen for soft spots
Red Flag: Musty odors or soft floors may signal hidden water damage.
Heating, Cooling & Propane
Comfort and safety matter. Test everything that keeps you warm (or cool).
- Run the A/C and check airflow
- Test the furnace and thermostat
- Check propane tanks, regulator, and lines
- Test LP-powered appliances (fridge, oven, water heater)
Safety Tip: Always ask for a recent propane leak test or have one done before signing.
Interior Condition: Live-In Readiness
Spend time inside and imagine daily life. Look for:
- Wear and tear on upholstery, blinds, bedding
- Cabinet doors that stick or hinges that squeak
- Unusual odors (smoke, pets, mold)
- Test TVs, radios, and any included electronics
- Signs of pests in closets or drawers
Driving Systems (for Motorhomes)
If you’re looking at a Class A, B, or C motorhome, don’t forget the engine side of the story.
- Does the RV start easily?
- Any unusual noises from the engine or suspension?
- Does it track straight on the highway?
- Are brakes smooth and responsive?
- Any steering issues or vibrations?
Pro Move: Pay a certified mechanic to do a pre-purchase inspection if you are unsure.
Paperwork & Proof
The best RV in the world is not worth much without clean documentation.
- Clear title (not salvage or rebuilt)
- Maintenance and repair records
- Owner’s manuals for systems and appliances
- Any warranties still in effect
