Only 500 lbs separate their combined GAWR yet the 2500s GVWR is 1,300 less due to class 2b trucks having a max GVWR of 10k. This is why I am not afraid to go over my 10k GVWR as long as I am under my GAWR. Because I know the reason is due to regulations and not actual truck carrying capacity. If I believed the 10k GVWR was due to the trucks actual carrying capacity then I would get a 1 ton.

Why is the 3500 GAWR 500lbs greater?

Is the 3500 GVWR 11,300 lbs limited on paper just like the 2500?
