There are allot of good used trailers out there, you just have to know what you are doing when looking one over making sure it isn't a POS that someone traded because of such...
Like Lyle I saw a few weeks ago a complete setup truck an trailer from an owner who passed away, the DW didn't want it because she no longer could drive an they were only a few years old, priced at 55k for the both. Had a friend that sold his 5th wheel that was about 6 years old, stored inside an was a really nice 5th wheel, paid about 70K for it, sold it for $15K, we would have bought it in a minute but didn't find out about it till after it was sold..
Again i believe you could get into a nice new Kz Durango Gold for allot cheaper than you think an you have a 2 year warranty on such bumper to bumper...Problem being Kz dealers in some area's are far an few between, goo thing about Kz is that if you are 150 miles away from your selling dealer you call Kz Customer service an the steer you to a dealer who will fix your 5th wheel under warranty :)
Safe travels an again good luck in anything you buy
