I do not own the truck or camper I intend to pair. I will be buying a 2018 or 2019 F350 XLT LB 4x4 super cab with camper package and 11,500# payload pkg, heavy duty 18-20" tires. I am looking at a 2005 S&S Montana Avalanche 992. It's listed dry weight is 3500# and wet 4000#. I have no way of figuring the trucks capability (except of course looking at the Ford specs, which I have been told not to rely on). This is a one of a kind camper around here. Truck campers are VERY difficult to come by. I am wanting to know if I am crazy to consider the purchase. Please don't be brutal. I really did try to do the math, but am missing way too many truck numbers.
