We are looking very seriously at a 5vr that total GVWR is 15,000 pounds. My dodge dually is 2001 dually. JUst had the tranny completely rebuilt and it has been chipped. Not sure about being able to ...

Let's see.....
We'll comply with the rear axle rating. The axle manufacturer knows what they are doing.
Well Dana the axle manufacture rated the Dana 80 at around 10,000#
We'll comply with the tire loading specs, those guys have their act together.
I believe the tires on a 2001 Ram DRW were 17" rated at 3,042# each so 12,168# of tire capacity.
We'll comply with the GVWR, Dodge knows what they are doing.
Well the 2001 Ram 3500 DRW had a GVWR of 11,500#, so should be within that spec.
The gross combined vehicle rating is idiocy and we will just ignore that one.
This is a power and gear ratio rating, comfort of towing.
Who decides which ratings to ignore and which to follow? Does chipping an engine improve the cooling capacity, shock damping, frame strength or any of a number of other factors Dodge considered when designing the truck and assigning capacity numbers? I choose to stay within the factory specs.
I towed a 32' 5er with a 2001 Ram 2500 Camper Special GVWR 8,800#. That 5er grew from about 11,800# to at last scaling 13,600#, last time I towed it with the 2500 it likely weighed in at 13,000# with a 2,700# pin. I was over GVWR by about 1,700# considering the 3.55's I was over GCWR of 16,000# by about 4,500#, still pulled hills at the speed limit (small chip and RV275 injectors) I also has an PacBrake.
NOT something I encourage others to do, but worked fine for me for six years. We now tow the same trailer with a 2016 Ram 3500 DRW 6.7 CTD and 3.73's, power wise far better, handling much also better, but the old TV never scared me.
