Arctic Fox 1150 is breaking my 2016 Ford 350 dually

We have a Snow River 8 ft on 2016 F350 long bed SRW. The wings of the camper clears the side rails and camper sits in the bed on two layers of 3/4 inch plywood so it clears the cab and obviously bed rails. We’ve put at least 50,000 miles in the 14 years we’ve owned it including 3 trips to Alaska from Michigan. Nothing damaged on our truck. No off-roading unless you count Alaska Highway!
