Arctic Fox 1150 is breaking my 2016 Ford 350 dually

I see I forgot we’ve had our current camper on TWO F350 trucks. First one is 2000 long bed, SRW. That truck has 200,000 miles now, hauled lighter camper then 9 years/25,000 miles of Snow River. Bed on that truck is fine,we still have that one- had frame tie downs. On 2016 have Tork Lift and Fastguns. Camper on 2016 now, waiting to see if Canada will let us in this summer!
