Bryan,
There is a lot of web sites out there than can help you. So do your homework and get the best for your situation. I had a 01 but upgraded to the 06 3500 DRW last month. I had all the goodies for the 01 2500.
Hope these sites help.
Good info for the Dodge: Turbo Diesel Register

I didn't know very much about diesels but he help out a lot. The local Cummins club led me to him.
I'm going to full time for a year down in El Paso, Texas. Should be HOT!
