I had a kitchen in the rear it was a Wanderer. Only time we had trouble with it was on the Alcan highway. We took a perma frost heave too fast and everything in the kitchen wound up on the floor. Of course that was not the fifth wheels fault that was the dumb drivers fault. But stuff happens. After that we bungeed all the cabinets closed for that trip. We had no further trouble. Except of course for the bent axles and cracked windshield. The great north west is very unforgiving. Ha ha ha.
