I used to be a 2003 6.0L powerchoke owner. I have a 2004 2500 4x4 QC Ram with the big "C". There is no comparison between the two trucks. I highly recommend a 2004 simply because the is no kitty on the exhaust. The engine and auto tranny is an awesome combo. I used to have "Blue Oval" running thru my veins. I should have switched to the dark side years ago:thumbsup:
