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

The camper obviously was not applying the weight between the two axles but rather cantilevered behind the rear axle, putting an upward strain on the frame. Much the same as a load distributing hitch hitch would do. The frame is most likely designed for downward forces, not an upward force. Like others have mentioned, it would be interesting to see the break. I wonder it it occurred where there was a hole in the top of the frame for the box mount or similar weak spot not intended to see tension but rather compression? And yes it was obviously overloaded.
