Another to think about. Assuming you ARE PUTTING 15000 lbs on truck bed etc. How is
S that weight centered? ALL going on the rear? If so you will find you.have 21000+ on the RA. Max you can do.legally is 20,000. I'm going on the fact mine is just under 6000 empty.
So you may need to have a longer CA bed length, so some of that 15k goes onto.the FA. OR, design in a drop axle just in front of the RA, so on the hwy you are legal, but off road you raise it so it is not in issue driving here. Then get a 22-25K capacity RA to handle this load off road.
Or you may need a 15k FA with.some super singles to carry spread the load forward, removing it off the rear. By putting the.load more forward 've in the rear.
GCWR on larger trucks, may mean for city.driving, vs over the road. Can will it hold 55 on a 1-2% free way grade for local driving. Vs holding 60 mph for over the road interstate setup. This Is based on HP needed to over come how many tires are on the road, aerodynamics of the setup, actual weight, road bed type. Tire design and tread pattern.....
A LOT of things to think about.

A lot to consider, will work on the numbers. Thanks for heads up.
