My ex rental with 125k miles on it is filled with new parts inside and out. New tranny, brakes, tires, new paint, new bedding, curtains, and much more. The thing about rentals is that when they break, they fix and replace stuff. In my experience, private sellers don't fix what is broken. They just want to get rid of the damn thing and make it your problem and they still want you to pay a high price because they are under water on their loan. That was my experience any way. And buying new? Forget it. Who wants to put down 20k and still have a 15 year mortgage on an RV? Not me. My advice is to buy cheap and old with cash if you can and then run it into the ground.
