Hello, I drive almost 125 miles round trip each day to work. My truck is sitting down in the parking garage right now with 25.6 MPG on the tank. I have the 3:96 gears and know without a doubt that my truck would do everything you are asking it to do and in a **** of a lot of comfort! My 07 Ram Hemi was great too but at average 16mpg...the choice was a total slam dunk. I have almost 22,000 on it and its perfect. Good luck!
