I have always been a Dodge man, just for the simple fact, CUMMINS.I have owned over 30 of these Cummins,but I ave made a change. Yesterday, my wife and I purchased a new body style 07 Chevy, 4 door, SWB,4x4, DURAMAX with an Allison. I will be using it everyday to pull my enclosed landscaping trailer, and I hope that the Duramax is gonna be as reliable as the Cummins.I really like the Duramax/Alli combo and love the truck itself. I really noticed today while pulling, fuel guage was falling fast! I hope ths gets a lot better. QUESTION the new truck that we just purchased has all of the screwed up looking exahust on it. Do you guys think that this is gonna be trouble in the future with all of the smog crap on it? By the way, it has 350 miles, bone stock,Im not putting an power adders , and the truck is strong.Hope it gives us YEARS of worry free service. Proud to drive the D max!!!!!!! thanks guys!!!!!!!!!!!!!!
