I can get a pretty good deal on a 2012 Ram 2500, 4x4, Cummins with ~100k miles. I know that the truck has been cared for. Things that I know have been changed after 2012: - New more rigid frame - New front steering to correct "death wobble" - New rear suspension (coil) - Front axle disconnect for 4x4 - Upgraded transmission cooling - Upgraded radiator - Upgraded intercooler - Complete interior overhaul - DEF for regen - Upgraded exhaust brake (multi stage?) Seems like a lot of changes, but as I said, I can get a good deal and I know the truck has been cared for. I plan to use this truck to haul my 6k lb boat and a 10k lb bumper pull travel trailer. Anyone with experience with this generation vs the current generation? Any changes that make huge differences?
