You will absolutely LOVE the drivability of the new diesel! You’ll also be happy to hear that they are much “happier” doing daily driver duties than their pre DEF years. Do your homework, there are gear ratios from 3.42, 3.73, 4.10. Picture this: coming up on the Cajon Pass with the cruise set at 55 and I just sat back and let the truck do the work.... all the way down that gawd awful grade. I was impressed. This was my friends 15 2500 4x4. It was a pleasure to tow with over my modded 01 for sure!
