Finally got my new truck from the dealer. VIN code has a big fat "D" in it. I thought they were putting the MDS Hemi in the lighter duty trucks but looks like the 1500 Megacab built on the 2500 chassis qualifies to not have MDS. Guess the extra weight is the factor. Not like Megacab owners are looking for gas mileage anyway. Kinda miss the Cummins loaner I had while I waited for my Hemi. That new Cummins with six speed auto is really sweet.
