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.
You gotta pay attention to what GM says.

Sorry. I didn't study the overly complicated chart for a GM enough (I don't know one c###### number from another).. I looked at the wrong numbers...and you are right; the 6.0 isn't a very capable truck in the HD format for 2011. My apologies to the OP - guess 4.10 is the only way to go with a GM truck of that vintage for that size trailer.
I guess I'm used to the more recent vintages of trucks, but I will say that I've had 1/2 tons (Ram 2012) with 3.55 and 3.92 5.7s that pull 10k OK....just a little overweight.....
My mistake. The tow ratings for that HD truck are about what they were for my 5.7 1/2 ton if I recall; I thought the GM would top that but should have double checked. Off the top of my head; not to start a debate.
