Nice Truck!! Great deal, too! If I'm not mistaken, doesn't the 02 still have the 7.3 PSD? I have a 1997 F350 Cre Cab PSD 4x4 Dually, and it has the Banks Stinger Kit on it. It runs fast and smooth! Without trying too hard (pressing the gas like I had to with my 94 F250 w/7.5L gas), I've broke the tires loose a few times pulling away from a light! I keep track of my gas mileage regularly as an indicator of how the truck is running (and my driving habits). With 4.10 LS rear, I consistently get 16.5-17.5 MPG.
The 2002 Dodge Ram 2500 extended cab 4x4 I used to have with the Cummins and 4.10's would get 17-18 MPG. It was all stock. I hated the way it shifted from first to second (auto).
I like my Ford alot better!
