The 3.0 ecodeisel was a joint development of Fiat (Ram) and Chevy so Chevy can use same or similar in theirs.
I had a dodge charger for commuting, a 8.1 L 3/4 ton suburban for towing, and a jeep for hunting and now do it all with this Ram 1500 ecodeisel. In 2019 models towing jumps to more capacity than 3/4 ton suburban.
