Looking at the specs
The idea is that the pin weight carries a portion of the weight. So while there is a 13,000 pound GVWR, less than 12,000 pounds would be carried on the axles.
Here's the math that I figure for this (assuming a loaded to the hilt camper).
Pin weight percentage:
dry hitch weight
/ dry weight
= 1,970 / 10, 654 = 18.5%
Pin weight at max:
* pin weight percentage
= 13,970 * .185 = 2,584 pounds
(Note, even this is possibly low since your pin weight sometimes increases as you add stuff to the front storage hatch.).
Weight at axles:
- pin weight
= 13,970 - 2,584 = 11,386 pounds
It doesn't seem like it would ever be over 12,000 pounds at the axles.
