Ive been in and around enough dodge trucks to agree that the truck itself is junk!
Cummins are great and many people out there dont even care how crappy the truck is because they only care that there is a cummins under the hood.
The DMAX is the diesel motor to have these days. It just doesnt get better. The DMAX is proving that it can go the distance, they make great power, get good mileage, and have few problems.
If you want a nice refined truck then the GM/Chevy is what you want.
If you want to be noisy, rough, and obnoxious then run the dodge.
