What First-Time RV Buyers Need to Know
Buying your first RV is both a big adventure and a big investment. If you are considering a used RV, congratulations! You are already being smart with your budget. But before you hit the road, it is critical to know exactly what you are getting into.
Used RVs can be an incredible value or a hidden money pit. That is why we put together this easy, step-by-step RV inspection checklist for first-time buyers. Use this guide when you are shopping online, visiting sellers, or walking through listings on RVOnline.com.
First Impressions: The Exterior Walkaround
Start by walking around the entire RV slowly. Take in the big picture, and do not rush this step.
- Check for dents, cracks, or rust
- Look for signs of water damage (bubbling paint, soft spots, discoloration)
- Inspect all windows and seals for fogging or dry rot
- Examine tire wear and date codes (replace if 5+ years old)
- Check the roof for cracks, mold, or missing sealant
Pro Tip: Bring a flashlight and inspect underneath the RV for rust, frame damage, or signs of leaks.
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.
- Take it for a test drive and check for alignment, acceleration, braking
- Look under the hood for leaks, corrosion, or frayed belts
- Check oil, transmission, coolant, and brake fluid levels
- Inspect the undercarriage for rust or oil leaks
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
Final Thoughts for First-Time Buyers
