With ours we have a 15,500# GVWR trailer. About 9000# for the loaded truck. That puts us right at the GCWR of 24,500# when running at GVWR for the trailer. Pin is heavy because we have a 290# gen and 200# w/d right up front. Two toolboxes, heavy hitch, and a 51 gallon aux fuel tank in the bed.
We're over the factory RAW by approx. 1300# at 7500# (RAWR is 6200#). Stock tires were 3100#/ea give or take, AAM rates the axle for 10500#. Kelderman full suspension replacement rated for 12000#. Vision 81 Heavy Hauler wheels are rated for 4500#/ea and tires for around 4950#/ea. So our RAWR as far as I am concerned is the weak link, wheels x2 @9000#, so we have a 1500# safety margin in there.
