car-fax

For your area, look for signs of flood damage, leaks, systems all function correctly.

Do a Google search for 'how to identify a flood motorhome.'
You will find several videos for inspecting flood/water damaged RV's.

The best way to tell if there has been any damage, from an accident, or a flood, is a very thorough inspection by a professional that knows what to look for.
As an example, we had our Jaguar automobile hit broadside by someone that ran a red light. State Farm totaled it, gave us a check, and sold the carcass to the dealer. The dealer repaired the extensive damage and sold the car within 30 days to an overseas buyer, with a clean CarFax. Apparently it takes awhile for the paperwork to catch up with a CarFax report.
The Chevrolet HHR that we are now using as a toad was purchased from Enterprise rental after it had received some minor hail damage. The out the door price was about 1/3 the MSRP for an 8,000 mile vehicle. The minor hail damage was enough to take the vehicle out of service as a rental, but since Enterprise Rental self-insures, there was no report to CarFax. I received a clean title. In other words, if you pull a CarFax report on my vehicle, it shows "no problems found" under hail damage. Basically what I am saying is do not trust a CarFax report to give you all of the information about possible problems with any vehicle.

That is probably the best way but, it's not realistic to have a pro thoroughly inspect every RV that interests you.
Learn what to look for, eliminate the junk, when you are serious about one call in the pro.

Get the VIN and plug it into Carfax, if there are any records registered they should show up. Did that with one I wanted to buy and 24 records showed up(not all good), I passed on that one. Also try putting the VIN into Google search and see what they find. Same unit showed up with 56 records, including a repo and several tows.

If it has a VIN than there will be a car-fax, however car-fax is not always accurate, some repair shops don't insert the info every time, also mistakes are also made, I had a 2002 Flair that showed the mileage jump 100,000 miles in one year that went back down the next, car-fax is a guide but not factual of its history.

Car Fax is a joke.....even for a car.
