When I first started on the RV "odyssey", I bought and read the "Idiot's Guide to RV'ing". In the chapter covering purchasing an RV, the author noted an RV purchased new will typically lose 40% of its value in the first 5 years of ownership. Don't know the supporting data behind the statement, but no question an RV is a depreciating asset. We traded an '05 HitchHiker LS last year on a new Jayco WhiteHawk. We received a trade allowance of 17K, about $4K below NADA "book". I was OK with it though since I didn't have the bother of attempting to sell our trade in myself.
