I have an '05 Ram 3500 SRW, same tires, same RAWR as your truck. The question is how much of that 16000 lb. fifth wheel you propose to get is pin weight, keeping in mind that some of the RAWR is already used by the truck and whatever you may have in it. We had a fifth wheel that had a loaded pin weight of just under 2300 lbs. and I was bird watching with the headlights at night until I installed air springs to level the body. You could probably accomplish what you are suggesting, but I'm thinking the rear tires are gonna be screamin' and the front end of the truck is gonna be light on the steering.
