It always a gamble with the unknown, get them checked out and get the one you really like. You will have more problems with the rv stuff than the chassis stuff. Look for rodent damage on both.I bought a ten year old rv that was in good condition. Have had my share of issues, Ignition failure ( had to be towed) , Autopark Failure ( towed again) Ignition relay failure. I have had this mo ho for ten years myself so this could be expected on a 20 year old mo ho. We love the layout we have not had any issues with ac's(2),fridge,hot water heater. No leaks and have a rubber roof that is original. Had generator stator go out and rebuilt. Heater went out replaced board. Cabinetry and construction of rv has held up good and is of good quality. If you buy I suggest you change fluids in everything including transmission and go for it!.
