I had a 2016 Ecodiesel for 3 years and put about 100,000 miles on it. Despite all the issues that generation of Ecodiesel had, my problems were minimal compared to what I read on line and in different forums. The biggest issue I had was a leaking EGR cooler which I found out after purchasing the vehicle used. During that 3 years I made two trips every year back and forth from North Texas to Northern Minnesota pulling a boat and had the truck loaded to hilt with bicycles etc. I measured my fuel economy with miles driven vs gallons used and consistently achieved a minimum of 14mpg which was the lowest while towing, and the best was a smidge over 18mpg when I had a south tail wind. Without the boat etc., fuel economy in the city was typically 20 to 21 mpg, and on long trips I averaged consistently over 25mpg traveling the speed limits which in many places is 75mph. Right now diesel fuel is quite a bit more expensive, somewhere in the $.75 to $1.00 range but we are living in an anomaly right now. In the past, diesel has only been a little more expensive, here in Texas about $0.20 to $0.40 but with the fuel economy both towing and empty, the Ecodiesel is cheaper to operate than the Hemi. As for towing, a Hemi may get to the top of the hill faster than an Ecodiesel, but the Diesel will pass many more fuel stops than a Hemi.
