The Pre-Purchase Inspection That Can Save Thousands

What to test, document and verify before accepting a new or used rig

A clean interior can hide a leaking roof, aging tires or an overloaded chassis. Whether the RV is new or used, a disciplined inspection should happen before final payment and before the buyer loses leverage. Treat the process as a systems test, not a quick tour.

Start outside and work inward

Inspect the roof, corners, windows, doors, lights, awning and every exterior penetration. Look for cracked sealant, ripples, stains, soft material and mismatched repairs. Underneath, check for corrosion, leaks, damaged wiring and low-hanging plumbing. Examine tire date codes, sidewalls and tread; confirm that installed tires meet required ratings.

For a towable, inspect the coupler or pin box, safety chains, breakaway switch, brakes and suspension. For a motorhome, review service records and arrange a chassis inspection. Verify the vehicle identification number against the title and sales documents.

Operate every system

Connect to shore power and test outlets, air conditioning, converter and appliances. Disconnect and confirm that the battery system carries expected loads. Run the pump, connect city water, fill sinks and shower pans, flush the toilet and inspect compartments for leaks. Test the water heater according to instructions.

Open and close slides, awnings, vents, windows, shades, latches and furniture. Confirm refrigerators cool in their intended modes and safety detectors are current. Do not accept 'it probably needs propane' instead of a demonstration. If weather prevents a test, write it as unresolved.

Measure, weigh and document

Confirm cargo-carrying capacity and understand how passengers, water, propane, batteries and accessories consume it. Measure real height, length and width after accessories are installed. For a trailer, verify the tow vehicle, receiver and hitch are appropriately rated for the loaded combination.

A qualified independent RV inspector can provide a valuable second set of eyes. Keep photos, test results and a written list of corrections. Reinspect repairs before delivery. A long checklist is not pessimism; it is a way to begin ownership with facts.

BOTTOM LINE Test every system under realistic conditions and resolve defects in writing before final acceptance.
