We have a 2015 with 78,400 miles. We've been in the shop for an EGR cooler, DEF injector, and MAP sensor replacement. Other than that, we haven't had any major issues. We do an enormous amount of towing with it. I would eventually like to buy a 2021 Ram Ecodiesel, but we are going back to a Cummins for most of our heavy towing needs.
