Just took a 2500 mile trip in my new Ram 4x4 . Got 26 on the interstates with cruise set on 75 to 80. Six banger with the 8 speed ZF trans. 5 mpg better then my Hemi with the 5 speed did on the same trip. I has all the power I need. The 8 speed helps the 6 cyl take off quite robustly. I don't tow much nowadays and really don't need the Hemi anymore. It actually feels faster then the 4.7 v8 Ram I had before the Hemi.
