RV OWNER’S FIELD GUIDE
What a Pre-Purchase Inspection Actually Catches
Buying an RV, new or used, without an independent inspection is the single most expensive mistake we see. Here’s what a proper PPI covers and why it matters before you sign.
Why an Independent PPI Matters
A seller’s walkthrough and a dealer’s “multi-point inspection” are not the same as an independent, third-party technician checking the unit with no financial interest in the sale. The most expensive RV problems — water damage, electrical faults, chassis issues — are exactly the ones that don’t show up on a casual walkthrough.
What Gets Checked
— Roof, seams, and seals — moisture meter readings at every penetration and seam, not just a visual look
— Water damage indicators inside — soft flooring, delaminating cabinets, musty odor, moisture readings behind panels
— Electrical system — shore power, converter/inverter operation, battery condition, and full function test of every circuit
— Plumbing system — pressure test, water heater operation, tank and valve condition
— Propane system — leak-down test, regulator condition, appliance function
— Generator — start-up, load test, and exhaust/carbon monoxide check
— Appliances — furnace, AC, refrigerator, and slide-out operation under real conditions, not just “it turns on”
— Chassis and running gear (drivable units) — tires, brakes, suspension, and undercarriage condition
The Most Common Costly Finds
— Water intrusion already active in the roof, floor, or slide-out seals, invisible without a moisture meter
— A converter or inverter that’s failing under load but works fine at idle
— A generator that starts but won’t hold a load — impossible to catch without an actual load test
— Undisclosed prior repairs or modifications that don’t meet code
Timing It Right
Schedule the inspection before final funds change hands, ideally with a contingency in the purchase agreement. A PPI that happens after you’ve already paid gives you information, but no leverage.
