Another good reason to buy used, about 5 yrs old or whatever, is the better chance of finding a mfgr that builds their own frames or uses a GOOD frame mfgr like Young, Venture or Dexter. A few that come to mind are HH, Jayco, Carriage, Sunnybrook, Newmar and I know there must be others. The 3 low end units we owned, had very flimsy frames and everything around them either worked loose or came apart. After a few trips with our 92 Sunlite hybrid, I thought my feet were going to go thru the thin floor. Our 94 Shadow Cruiser 5er only had a 2 x 4 frame and the entry door wouldn't open/close if I put too much weight on the back jacks. The siding was popping off of our 98 FR Wildwood 5er from the front end flexing. When it comes to Rvs its... pay now or pay later! Craig
