If the 2014 Ram with DEF only gets 16-18 mpg hwy then it looks like the DEF is only a bonus for less regens. My 12 CTD gets 16-18 mpg hwy all day @70 mph. 18-19+mpg running 55-60.
But, there's no accounting for driving style (or BS). From 2007.5 on, owners (at fuelly.com & various forums) seem to report anywhere from 12 to 22 mpg highway (with and without deletes). A friend of mine just purchased a new 2014 2500 CC SB Tradesman 6.7 4x4 SRW. We just did a 100 mile loop empty at 70 mph and he got 19.3 mpg hand calculated. I mentioned 16-18 mpg highway in my post because these numbers seems to bring up the least amount of controversy with late model 6.7 Cummins owners--plus, 17 (or 16-18) is the result of averaging 12 and 22.
