Actually the biggest reason for no cummins is the intercooler and radiator size. If you ever get a chance to look under the hood of a gas powered ram and a diesel one. You'll notice that in the gasser the radiator is actually offset to one side and all the coolers are off to the other size.Lleaving tons of room between the grill/bumper and the core support, about 6ins or so. On a diesel truck with the huge ass radiator and intercooler plus all the other coolers stacked in a row there is a very small space left till you hit the grill/bumper. This extra space on the gassers is used to "hide" the winch. There is some space on the diesel trucks but not as much.
Having a 2003 dodge cummins, I can't say I would want to do any serious four wheeling with it. Its 23 feet long AND weighs 8000lbs
. That would seriously suck to get stuck with
. I have no problems doing fire roads and very mild trails, but that's about it. I have the chevy for the little crazier stuff
, course it weighs about 6000lbs on its own
. So not to much weight saved.

I would also take a Hemi powered version over a Cummins anyday if you were strictly talking off-road performance
