I found a 336BHS Cougar with a pin weight of 1910 and UVW of 10325 and input those numbers into Towing Planner and came back with a loaded pin weight of 2545 loaded ready to camp.

Now you can take you 3483 payload and work up what weight you can carry. I'm going to input 200 pound driver, 150 pound passenger, 200 pound hitch and 50 pounds misc and comes out to be. "You're adding approximately 600 lbs. to the truck. You have 2,883 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 11,532 - 14,415 lbs."

Using the Stubby Pencil it looks like it great match but you still should verify the numbers by bring it to the scales.
