All the cummins guys claim 20+ mpg and I have had 2 24 valve 5.9's and a 6.7 cummins and even though the display shows 17mpg, on paper it always came out to 12-13 mpg.

I agree. If I drive it, it seems to drink fuel. Where people claim 14 - 16, I get about 12 with the same setup. When I am feeling cheap, I drive my Honda that gets 65 to 75 MPG - I even hit 86 one time.
