The deal is they are hard mounted to the frame, and never intended to be structural member. Hard mounted to frame causes them to flex if the frame flexes back there.
What would cause the rear frame behind the wheels to flex, you ask. Heavy bottoming out on the hitch, dragging the hitch or skid plates sideways, or heavy towing. Before anyone gets their dander up, the coach should handle that. The problem is the radiator should not be hard mounted. We need to put our guru heads together and come up with a floating mount system. If you look at your cars or any big truck, the radiator is NOT hard mounted. They have rubber isolators of some sort between them and the frame.
