I don't think the Cummins or 6.4 will make a bit of difference with a Camper on board. I am sure some of the weight will hit the front axle but I really don't see a problem with the Cummins up front.
x2. I know the 6.4 has higher payload "on paper" but a quick look at the Ram
towing and payload guide can be telling. First, the one 6.4 truck with highest payload was the 6.4 with 4.10 gears. The same truck with 3.73 gears has a lower GVWR by 700 pounds despite having the exact same FGAWR and RGAWR! That makes no sense at all, gearing should effect GCWR but not payload. Anyway, the Cummins trucks have an extra 500 pounds of front axle capacity to help offset the weight of the diesel. The real take home is all of the trucks in the config I checked out (4WD crew cab DRW) have the same RGAWR and the empty rear axle weight was within 100 pounds on all 4WD CC DRW models. So in reality they can all handle about the same weight camper. Now, I know the 6.4 will move down the road just fine at GVWR, but if you would prefer a diesel, don't let the 'on paper' difference of 1000 pounds in payload sway you, because when you break the numbers down to what counts the difference is much less.
