You are WAY WAY overweight. Air bags, LT tires, they do absolutely nothing for your legal weight capacity of that truck. That camper will be 10,500 pounds easy when you load it up. Don't believe me? Run it on the scale, costs $9. Camping gear (towels, sheets, food, clothes, firewood, batteries, propane, etc etc adds up FAST. You need to read the fine print on the tow ratings *assumes 2wd, regular cab, stripped with roll down windows, only driver of 150 pounds. Unless you are 150 pounds, don't carry gasoline and are not taking anyone camping with you, this is not accurate. The tow capacities are calculated using the lightest configuration of the truck empty and subtracting it from the GVWR of the truck. That truck is not designed to carry that amount of weight, that 5th wheel will grossly overload the rear axle capacity of that truck. The camper sales guys are trying to make a sale, I have had them tell me to go ahead and pull a tri-axle toy hauler with a F250 because "everyone does it". Not flaming away, just concerned for your safety and those around you as that is way too much camper for a 1/2 ton truck.
