I have had good service with my 02 crew cab with the 6.0. You can find them much cheaper now along with the comparable Ford gas 3/4 ton as well. My thought is to go drive several types and choose the best for you. I went the 3/4 ton route due to future upgrading in which I did. I like owning a truck with a lot of payload. The 6.0 pulled better then my 5.3 did, the main reason is that it stays in gear longer. It seems to not strain as much as the 5.3 did, just my experience. Anyway good luck on your search, take your time and drive different brands. You will find the one ment for you.
