When it comes to fifth wheels, the important number is the payload capacity of the TV. Because the fifth wheel applies a considerable amount of weight on the TV, typically a 3/4 ton truck will max out.
The TV's payload rating will be on a placard on the driver's door jam or door, usually it is on the same placard that lists the tire pressures. Your RV dealer or a sticker on the fifth wheel would be the source of the RV's pin weight, typically a dry weight, that is, before you add your things like clothes, dishes, etc.
Googling you trailer, I found the pin weight of 2,110 pounds dry. 14,110 gross weight which lines up with your numbers. Rule of thumb is a fifth wheel's pin weight will be around 18 to 22 percent of the RV's weight loaded.
