Just wanted to throw my .02 in here. I bought one of the very first Ram Ecodiesels when they came on the market in 2014. Mine currently has a little over 100k and has been great truck. My reason for posting is just to give my side of what the appeal of these 1/2 diesels is. Mine gets real world 20-22 city mpg... and that is with me mostly stomping on it everywhere and gets 26-31 hiway going 70-75. My buddy has a 16 with the 3.5 eco and there is no comparison in terms of raw acceleration. But while towing they are pretty similar. I routinely get 16-17 towing my 3 place enclosed at 70mph also. I don't think I could go back to a gasser and be stuck getting 10mpg pulling a trailer again. All that said these trucks are like any other half ton and they are happiest pulling around 5k lbs.
