What Cummins12V98 is trying to point out is that the 5'er does not add any additional weight to the front axle. Therefore it's OK for the diesel engine to max. out the FAWR.
I am not a tire and axle rating only guy.
I believe in staying within all the ratings including GVW.
Nevertheless I understand the point he is making.
This post isn't about maxing out the FAWR, this post is about why the OP's truck only has 1860 pounds of payload available for pin weight. And my post (wherein I was resoundingly told I was "Wrong") was all about the 800 extra lbs that diesel engine weighs gobbling up payload.
You can read my post, it's right there in the middle of page 2.

That Turbo Diesel option you paid $8,000 extra for just chewed up about 800 lbs of your payload. You should have gotten the gasser and you would have had 800 lbs more payload and you'd be good to go.
Yep, the catch 22 of owing a 250/2500 diesel compared to gas.
Diesel can't carry what it can pull easily within the numbers.
Gas may struggle to pull what it can easily carry within the numbers!! :S
The reason you see many 250/2500's hauling bigger 5er is that many ignore the Class Limited GVWR of 10,000# or less and go by the rear axle GAWR. While I do this myself, but I don't recommend it, to others as it is a personal choice to exceed GVWR.
In truth I didn't do the calculations when I bought our current 5er, I used the highly non-technical method of hooking up the 5er to my TV too see how much squat I ended up with. Well about 1.5" or so, done deal on the 5er. This is on stock suspension. :)
I think you find that while new Ram 2500's have very close or at 10,000# GVWR, the first couple inches of travel is softer than mine so the same pin weight will induce more squat, this why you see so many post about air bags.
Well once scaled yes, over the listed 8,800# GVWR of the 2001 Ram, but still well under the rear axle of 6,084, which the optional tire far exceed. My pin is around 2,200#.

Yep, Nick is correct that the Cummins eats up about 600# to 800# of payload over the Hemi.
What Cummins12V98 is referring to is the method of using the Rear axle capacity to figure how large of a 5er one can Carry/Tow.
Many realize that the Class limited 10,000# GVWR of 250/2500 is only there for Tax and registration reasons in some crazy states that think that all 350/3500's are used for commercial work!!!
While exceeding the listed GVWR for a 2500, may open you up for a lawsuit if in an crash, so the choice to exceed it is a personal one. The 2500 is the same as a 3500 SRW with the likely exception of the stiffness of the rear spring pac.
I think the crazy part is that a lot of business now use 150/1500 to avoid the cost of registration cost of 250/350/2500/3500!!!
