Start with the maximum payload on the yellow sticker on your door (probably about 1200 lbs) and subtract 150 lbs for your fifth wheel hitch, then subtract the weight of any passengers, cargo you "must carry" in the bed of your truck and the weight of anything you have added since the truck was new (running boards, cargo mat, bed liner, mud flaps, etc. What is left is the maximum "loaded weight" of the fifth wheel pin. After you calculate that estimate, start looking for a fifth wheel with a "loaded pin weight" that is less than that and you'll find your options for fifth wheels.
