I have been trying to make up my mind on which diesel truck to buy and did a few test drives this weekend. I have read a few posts here that are somewhat concerned about the competition out performing the Cummins. Well I just don't see it. I could only find an SO auto Dodge to test and it was much more responsive than the Duramax and felt much quicker. Plus the Dodge handled, rode and stopped much better. The Chevy did have a nicer interior that felt a little higher quality and a few more bells and whisles but I personally am looking for a truck. So I have decided on the Dodge. Now the question is an '03 or wait for an '04. Does anyone know of any changes ahead that might be worth waiting for? Oh, by the way, the four speed auto seems much more suited to the Cummins than a five speed does to the Duramax. I am planning to get a 2500 Quad, HO, auto, 3. 73 rearend. I hope to get about 20mpg on the high way. Does that sound reasonable? Thanks for any input, great website.
