My 2015 2500 6.0L LT Z71 comes in at about 7200 lb with full tank, two people, and a couple hundred pounds of tools in the back. Put it on the scale at my local grain elevator right after buying. So that left about 2300 lb of payload to get to GVWR of 9500 lb. Total GCWR is 20,500 lb. So with pickup at GVWR, that leaves 11,000 lb left for towing. Considering part of that 9500 GVWR would be trailer weight also, 13,000 trailer would be no problem. That is what the used on the Ike Gauntlet truck test of the 2015 2500 6.0L. 13,000 lb of trailer with three people on board and 500 more lb in the bed to get to 20,500 GCWR. Did pretty darn well. Better than the Ram 6.4 that had 500 lb less.

for info on towing, google GMC trailering guide, the GMC web site is better than the Chevrolet one.

There is a PDF you can download that has a lot of good information. You also can surf over to the Chevrolet web site and check out your mode truck and compare to similar truck model/configurations to see towing capacity. But the GMC pdf document is the best I've seen on the new GM stuff.
