Considering the trucks have completely different rear suspensions, leafs vs coils, it is a bit of a presumption to assume the only difference is "paper".
That's not what I said and don't put words in my mouth. The paper limitation I mentioned is because a class 2 truck by definition has a max 10k GVWR. Apply that to heavy diesel truck and that's your on-paper limitation. Nothing more than simple math.
In comparing the tucks, Ram rates the 2500 rear axle at 6500 lbs and the 3500 at 7000 lbs. I never said or implied that this difference exists only on paper.
