Determining Rear GAWR
I was reading another post and it got me wondering... I have a 2013 2500 HD with a rear GAWR of 6200 lbs. I have 265/70R18E Michelin's with a max load of 3525@80 psi per tire giving me a tire load cap...

My buddy has a 2014 Ram 3500 SRW/Cummins 4x4.
It has the exact same wheels and tires (size, type, brand) as my truck, but has 500# more rear GAWR (6500# to his 7000#). Must be the springs.
If your friend has an 2014 HO the ring gear in the diff is bigger than yours and either way, he has different and bigger wheels (18") than you and while I'm not positive, I think he has bigger brakes than your 07 has.
I have a 2014 now....exact same wheels and tires (18" Firestone Transforce HT) on my 2500 gasser and his 3500 SRW Cummins. The brakes appear to be the same by visual inspection, though I haven't compared part numbers to be sure. The tires have a max load of 3640# each @ 80 psi. 3640# x 2 = 7280#, but my rear GAWR is 6500#, his is 7000#, both are under max load for the tires.
His is not the HO, it is a 370/800 68RFE 3.42.
