Buying a Used RV: What to Check Before You Sign

Confirm Ownership Before You Get Attached

Before you spend time and money on an inspection, make sure the person selling the RV is legally entitled to sell it. Ask to see the title and match the name against a photo ID. If there's a lien listed on the title, ask how the seller intends to clear it at the time of sale, since a vehicle with an open lien can't legally change hands until the debt is settled.

For any RV that requires state registration, you can typically verify the vehicle identification number (VIN) matches the title and confirm there are no reported liens through your state's motor vehicle department. This is a small step that protects you from inheriting someone else's unpaid debt or ending up with a vehicle you can't register in your name.

Ask how many owners the RV has had and how it was used. An RV that spent years as a full-time residence has a different wear pattern than one used a few weeks a year for vacations. Neither is automatically better, but the answer should match what you see during inspection.

Read the Maintenance History Like a Timeline

Maintenance records tell you far more than mileage alone. Ask for receipts or service logs covering oil changes, generator servicing, roof and seal inspections, brake work, and any repairs. A consistent pattern of upkeep is a good sign even on an older unit.

Gaps in the record aren't automatically disqualifying, but they mean you should look more closely at the components those gaps would have covered. If a seller has no records at all, plan on a more thorough independent inspection to compensate.

Mileage matters less for an RV than it does for a typical car, especially for towable units that have no engine of their own. For motorized RVs, moderate mileage with good service records is generally preferable to very low mileage with no service history, since long periods of sitting unused can cause their own problems with seals, tires, and fluids.

When reviewing records, look for:

• Regular fluid and filter changes appropriate to the age of the unit
• Roof and exterior seal inspections, ideally at least once a year
• Any record of water intrusion repairs and how they were addressed
• Tire replacement dates
• Recent brake, suspension, or generator service for motorized units

Inspect Tires Carefully, Regardless of Tread Depth

Tires on RVs often age out before they wear out, because many units sit parked for long stretches between trips. Check the manufacture date code on the tire sidewall rather than relying on tread depth alone. Look for cracking in the sidewalls, uneven wear, or bulges, and ask when the tires were last replaced. Tires older than the range recommended by tire manufacturers for RV use are worth budgeting to replace soon, even if they still have visible tread.

Check Thoroughly for Water Damage

Water intrusion is one of the most expensive problems an RV can have, and it isn't always obvious at a glance. Walk the interior looking for soft spots in the flooring, discoloration on ceilings and walls, and separation around windows or seams. Press gently on walls and ceiling panels near corners and seams, where leaks most often start.

Open cabinets and check under sinks for staining or a musty smell. Check the roof itself if you can safely access it, looking at seals around vents, air conditioning units, and antennas. A moisture meter, which a professional inspector will typically carry, can detect dampness inside walls before it becomes visible as damage.

Test Every System Before You Commit

Run every appliance and system you can while the RV is connected to power and water, if the seller allows it. Turn on the refrigerator, stove, water heater, furnace, and air conditioning, and let them run long enough to see whether they hold temperature or cycle properly. Flush toilets, run water at every faucet, and check that the water pump builds pressure normally.

Check that slide-outs extend and retract smoothly, and that awnings open without binding. Test all lights, the electrical system on both shore power and battery, and any leveling system. Look underneath for obvious rust, damage, or fluid leaks.

For a motorized RV, take it for a drive if at all possible, paying attention to how it brakes, steers, and handles at highway speed.

A independent inspection by someone experienced with RVs specifically, rather than general automotive repair, is worth the cost for any purchase you're seriously considering. An inspector can access the roof safely, use tools to detect hidden moisture, and check systems a casual walkthrough will miss.

Bringing It Together

No single factor should make or break a decision on its own. High mileage with excellent records, moderate water staining with a documented repair, or older tires on an otherwise well-kept unit are all things you can weigh and negotiate around. What matters most is that the seller's story, the paperwork, and what you find during inspection all line up. When they don't, treat that mismatch as the most important piece of information you've gathered.
