I have a '16 Ecodiesel. Love the truck and gets great mileage usually 22 everyday driving and 26+ on the highway depending on how heavy my foot is. So far the biggest complaint was the junk tires they put on them from the factory. Replaced them before 2k after popping two of them on Weyerhaeuser roads. The ride on the truck is very smooth and quiet, for a diesel you can hardly hear it compared to the hemi. Have only towed a quad trailer and it did well, but I would be reluctant towing a bigger travel trailer as it does lack the horsepower compared to the hemi. For what I needed in a truck the ecodiesel works great, I looked at the Titan and Tundra's but just couldn't stomach the mileage on them.
Hope this helps.
