I think i have a comparison for you guys.... check out the domestic companies making the most money in the open markets these days. It IS DC and Cummins. I like all the trucks for different reasons, and i have seen quite a few HIGH powered trucks that are modified all to hell. However, the most industrial based setup, and the only one that is used for medium duty, as well as has the longest service life, is the cummins. It gets a 50k mile longer rating, and makes nearly the most power WITHOUT .7 liters on the Duramax, AND it is lacking all the aid of the gadgetry on the 6.0 and LLY/LBZ d-max. No VG turbo, and it doesnt have the HEUI/cat( i think) style injectors that international uses in the powerstroke, which in the 6.0 worked so well they melted a piston and popped a hole in another piston I guess when i hop on dodge websites and see 1/2 as many people bitch about nearly as much crap, i will venture elsewhere... for now, im getting rid of my f-250 for a dodge!
