Welcome and good luck in your search.
The seller will not do anything to help you with any kind of an inspection. If you want it inspected you will need to take care of that yourself. To inspect, your guy will need to go to the seller's location. If you are purchasing from a dealership, the dealership will have it's own inspection in preparation for sale. And of course they will tell you everything checks out. You can believe them or not believe them. Buying used, sometimes you just never know until after you actually purchase and start using the RV.
In preparation for purchase, have the dealer (owner) plug in power, run water through all the systems, demonstrate the holding tanks, operate the furnace, refrigerator and water heater. You as the buyer, need to look for any signs of water leaks, crawl under the camper to inspect lines, cables, flooring, anything visible. Check tires, looks for cracks in the trailer frame, and question everything you see. You can do your own inspection. Just remember, if something does not look right, don't feel bad or feel intimated to just walk away and tell them to forget it.
There will be something you won't like about a used unit. You have to decide if this is something you can live with or not. Only you can make that decision.
If purchasing from a dealer, you do have easier avenues for financing, and getting assistance getting the tow vehicle set up with proper hitching.
Hope this helps. Good luck in your quest!
