If you happen to be in an area with limited diesel emissions testing and can tolerate a little bit louder exhaust there is absolutly nothing wrong with the newer dodges as long as you stay 2010 and back. I drive a 2008 with all emissions junk "missing" and quite a few other mods, and while I still don't get quite the mileage of the older 5.9 cummins I manage 25-27 hwy hand calculated and 20-23 in town. Rides great and has no problems but if there was to be a problem Id feel a lot more confident under the hood of a cummins than the newer ps or dmax, not saying their not great trucks because ones just as good as the other these days but the simplicity of the cummins is still pretty close to what it has always been.
