Makes no sense why a bigger engine can CARRY more. They both have enough raw power to tow way more than their payload.

The Cummins have the lowest payload of them all...
I ask because DOT scales here do enforce GVWR. They don't care how much you tow (as that's a powertrain warranty spec).
Seems stupid the weight capacity is held back by a lower spec powertrain. I agree profit margins is all I can think of.

You must mean all the 5.7 and 6.4 2500 trucks as all 2500 5.9 HO trucks starting in '03 came with the 11.5" AAM rear axle.

Ram Body Builders guide shows the 2500 6.4 hemi has quite a bit more GVWR payload on certain models and the 5.7 has about the same on other models.
Also the 2500 6.4 hemi has a 10k gvwr and 6500 rawr 11.5" AAM axle.
The 2500 5.7 Hemi has a 9000 gvwr and smaller 6000 rawr 10.5" AAM axle.
Gotta' keep in mind those yellow sticker payloads are GVWR based and the 5.7 hemi with lighter weight tranny...front and rear axle will have more gvwr payload.

If you are talking towing, I would buy that.
But doesn't do anything for Payload. In fact a smaller lighter engine should result in greater payload. Any of these engines, the engine is more than enough to handle the truck at max GVWR (which doesn't include towing).
