Newbie trying to match a TC to my 1500 HD

What is AAM rear axle rating? How does this compare to rear GAWR? He has a 2012 2500 HD D/A 4x4 crew cab and stated his specs are as follows: GVWR=10,000 lbs., GAWR(front)=5200 lbs., GAWR(rear)=6200 lbs.
His E rated tires are approx. 3000 lbs. each = approx. 6000 lbs. max capacity. How can a rear axle rating alone exceed GVWR?

Now, I would never try to compare my motor and trans.(6.0/4L80), to the 6.6 Duramax/Allison. However, the issue pertaining to this entire thread is PAYLOAD correct? His truck weighs somewhere in the range of 7,200 lbs.

10,000 lb. GVWR - 7,200 lbs. truck = 2800 lbs. payload.

Those 2500 HD D/A trucks are certainly pullin' bad mamas, but many forget the additional weight of that setup. Unless I completely missed this, am I really being that "silly" when comparing them in terms of payload??

Welcome to the TC world.

You can learn more about trucks here than any salesman has ever told you.
Suspension, cooling, electrical...there is an expert somewhere on this forum that will help you...if you want to listen.
The TC Guys have been there/done that.
It is not likely any other type of RV owner(TT, 5'er) pushes their truck to the limit like we do, so we have learned by necessity.

BTW; hauling a TC has nothing to do with "bad pullin mama's". It is all about axle capacity. Forget payload, forget tow ratings...

AAM = Mfr of the axle.
The 2500HD RAWR from factory is limited by tires/wheels. Which are easily upgraded.
1/2 ton truck are limited by the semi-floating axle itself. Not so easy to upgrade.

Stop by TCU and do some reading.

Again, the short answer is you can find a TC that will work with your truck. Go one step at a time.

Good luck, Bill
