That is the main thing to know when you buy a Dodge truck. If you trade every few years, a Dodge will kill you on depreciation.
I've had a few over the years with the Cummins engine both for competition and towing. I've seen Gen2 Dodge pickups with the Cummins with over 1 million miles on them and the engine was still original. Nothing else was, but the engine was still running strong.
Probably because Chrysler didn’t build it.
