I've not bought an RV off of eBay but I have sold several. None of the buyers actually bought through eBay but they did CONTACT me through them. As a seller I would never expect to receive a contract to buy without them checking the unit out. I always try to be overly descriptive and upfront with the good, the bad, and even the ugly.
If you see a unit on eBay, then by all means contact the seller, ask all the questions you have, and ask to be contacted should the unit not sell. To me, eBay for large items is just a billboard to attract an audience.
