There are two sets of inspections: a) the inspection of the RV itself: engine,txn,brakes,tires,electricals etc and b) the 'insides' that is the appliances:tv,furnace,aircon,water system,stove and fridge,plumbing,cabinetry. You need to check for the exterior especially on the roof for leaks due to poor/old caulking, pest damage ie from mice, interior waterleaks by windows and doors. So what I did was buy my Sprinter from an rv dealer who a) provided a complete history of the stuff in a) and b) above. If tires, for example are over 4 years or so, they need replacing, regardless of wear. What kind of rv is it? You can get a checklist to check from the manufacturer/online or from an RV dealer. Is there a good RV dealer in the area of Virginia where the Rv is located. It sounds like it is a private rv? Can the seller provide proof of the above including that it is free of debts, or claims against it and has nothing wrong with it. Sellers will lie like crazy sometimes. I got a full repair history plus a full report on the condition of the rv itself plus all the interior stuff. If it looks good it may not be. Hope it works out for you.
