I have a 2001.5 Dodge 24 valve, 6 spd. 3500 Dually with the Cummins. I can get over 20 MPG. But, I have to be real light on the pedal with 900 ft. lbs. of torque on tap (several mods). Over 65 and it really drops because of the aerodynamics and tires (dually).

That is actually pretty believable. I have some friends that drive the D'max in different varieties. That is not an average. But he probably might get a tank or 2 with those MPG's. I have seen it. Not bad for a truck weighing in at over 7,000 lbs. Over time his average will drop if he is tracking every tank and "averaging all of them".
