I had an 03 Dodge with the Cummins and a m6. IMHO I believe you can't buy a better truck for an everyday driver and tow rig. I now own two LBZ Duramaxes and I like them both but as far as mileage goes they won't touch a Cummins :(. But as far as performance I would much rather have my Duramax

. The new Fords have a nice interior and I have heard that their new trans is supposed to take 550 hp with no mods

. Now that is impressive! I will still have to stay with my Duramaxes though cause I am just a GM fan at heart
