Chassis flex...interior doors wont stay closed when hitched

Our Fuzion was the same way with the door leading to the garage and master bedroom. The bathroom door stayed latched whether hooked or unhooked. I just adjusted the latches so the doors would stayed closed when unhooked and level. When traveling I had door stops for the doors so they would not swing back and forth while under way.

Makes you really wonder what is going on with that trailer frame.
