An Eagle Cap Camper Snapped A Ram 3500 Dually In Half, Mopar Refuses $17,000 Repair Bill

I would more blame the camper designer than Chrysler. There is more to it than just weight, which apparently exceeded the vehicle's rating regardless. I too suspect an fwd-rear rocking oscillation which broke the frame from metal fatigue, like bending a paper-clip back and forth. Might occur at certain speeds, dependent on the moment of inertia of the camper and spring-rate of the suspension.

I worry about many products, especially electrical from a perhaps unknown Chinese factory. If their incompetent design burns down your house, what is your recourse? At least if branded, you can go after them. This Eagle Cap company might declare bankruptcy if this is a generic problem, and proven that they spec'ed their camper to work on that truck. I give wide-berth when passing a pickup camper on the freeway, as some are rocking back and forth scarily, with the driver barely in control, though some of those idiots still speed.
