Dry weight of the camper the OP listed is 12,095 lbs. Dry hitch weight is 2375. The GVWR of the camper is 15,500 lbs. I would be willing to bet the wet and loaded hitch weight is in excess of 2700 lbs. A F-250 crew cab lariat 2wd typically has a payload capacity of ~2400 lbs which is before the hitch is installed and anyone or anything is in the truck. If it is a 4wd then the payload capacity is typically around 2000 lbs. Unless the OP has a more stripped down truck or a regular cab, I suspect donn0128 is correct in his assessment.
