I can't speak to the 06's, but my 01. 5 and 04. 5 have both been great trucks. A lot of people praise the Cummins and bash the Dodge part of the truck. I think the whole package is great. I've never had any serious truck problems and zero engine problems, and the dealers have always taken good care of me. Neither Ford nor Chevy make anything I want. I love the long box quad cab. The Ford and Chevy extended cabs lack the 4 real doors and the crew cabs are tooooo loooong. The Dodge is just right. I also really like the manual trans, and both Ford and Chevy derate the engines with a manual trans, if you can get it at all. Color me a happy camper.
