Bought a Dodge Ram 2500 with 6.7l Cummins... Love the drive line... Front suspension issues - had to replace 4 ball joints & 2 front shocks at 18000 miles... mostly highway driving. (and I'm not plowing snow w/ this truck) While the rest of the truck seems bullit proof, I have concerns about the longevity of the front end on this 4 x 4 truck...
6.7 Cummins is a big improvement over the 5.9 Cummins - torque & usable power curve are superior. Can haul 2200 lbs at highway speeds over long distance very comfortably - no shifting - hunting on the trans. - nice positive transmission shifts on 6A... Exhaust brake works great!
Would definitely like to see ball joints w/ grease fittings as OE... will likely need to do ball joints again prior to warranty lapsing and then upgrade to aftermarket balljoints with grease fittings
