"Steved", I have the same question as "JGoss".
I have also been told by Dodge service reps and by sales reps for the manual's publisher (Tech Authority 800-626-1523) that they imagine I should buy the 2004 Service Manual but implied in their answer is that they do not know for sure.
Have you noticed any differences between the 2004 Service Manual (SM) and the 2005 SM that would confirm for 2004. 5 owners which one should they get?
Also, can you post the link you used to download the catalogs? Thanks.
