3.73 Max Trailer = 9,600, and GCWR is 16,600
4.10 Max Trailer =13,000 and GCWR = 21,100
Wouldn't be too hard to exceed the limits of the truck with the 3.73 with a big trailer. If you go with an Oil burner and 3.73 the numbers get better pretty quick.
You gotta pay attention to what GM says.

Ford is the same way. The weights are determined by how much the drivetrain is stressed. (U-joints, driveshaft, bearings, etc). The taller gears means less strain which allows the weights to go up.
