Our first two years with our rear kitchen we would have just as much movement of things in the bath as we did the kitchen, which wasn't all that much. This spring we changed trucks and I installed a Trailer Saver air ride hitch, put a Center Point air suspension on the trailer and balanced the tires. Now we have virtually no movement of anything, anywhere. With the money spent I would hope not. Actually, the air ride stuff was added to reduce stress on the fifth wheel when we hit some of the really rough roads we encounter on occasion.
