Read the thread that was in my first post. Problem was most severe with the front bed models, but did happen with some of the rear kitchen ones too. The frame was the same depth as the 16's and 19's - but flexed too much for a 22 footer. Analagous to using 2 x 6 for floor joists over a 20 foot span. might be FINE for a garden shed, but will make the floor a trampoline on anything bigger. Add the normal vibration of a moving trailer and hairline cracks will start.
The 25 had a frame an inch deeper and Airstream eventually started making everything over 19 with the deeper frame. The OSB floor also contributed to the problem. It lacked the resiliancy of real plywood... and OSB turns into moist Kleenex when wet!
