I can't imagine licensing fees would impact official towing capacities? Fees vary from state to state. Towing capacity must be measured objectively using power, weight, braking, and physics.... But perhaps you are on to something, I am going to look at Ford and Dodge to see if they have similar disparities of towing capacities on their 3/4 ton trucks.

To be clear, its the same truck configuration. Both CrewCabs, both diesels, and both 3.73 rear gearing. The only difference is 4WD vs 2WD.

I have been doing a lot of research on towing capacity of the GM 3/4 ton trucks between 2015 and 2019. Can someone explain why the 5th Wheel Towing capacity on a CrewCab, 4WD, StdBox is 1900 lbs less than the same truck with a 2WD? I would normally expect that difference to be about 200-300 lbs between the 2WD and 4WD drive variants. In general when looking at the capacity chart for 5th towing on a 2500, the capacity ranges seem to vary widely. In fact on what I would expect to be the most popular configuration, a 2500 CrewCab, with Duramax, and Std. Bed, is only rated at 13,400. This just seem really low to me for a 3/4 ton pickup. What am I missing? Thanks in advance Ron
