TXiceman's advice is good and applies to the vast majority.
Another over generalized statement.
Fords fleet service specs show the 6.7 F350 SRW super cab in a 11500 gvwr with 7000 lb rawr can tow up to 16k + lbs and has a 4200 lb payload. Std cab has even more payload.
In fact a '12 LTZ 4x4 GM dmax 3500 SRW 11000 GVWR package and 7050 RAWR extended cab can tow 17k and has a 4050 lb payload according to GM online ordering guide weight calculator.
The DRW trucks have roughly another 2000 lbs of payload above the one ton SRW same truck configuration which the OP will have with his new F350 DRW.
