I just left Phoenix area. Heading to Oregon via I 5, my 03 Ram 3500 has never done great on mpg. So I bought one of these with hopes. Well, I did 10 mpg every tank full on the flats, and in the mountains. What make this worth the money to me is, I set the cruise at 63 and sit back. Going up the mountain with no kicking in and out of the passing gear. A smooth and easy 1800 rpm.
