Just going to say hey. I just bought me a CCSB '05 Duramax about a week ago. I love it so far got to get my 5th wheel hitch in to see how good it pull my camper. I'm at the beach right now so I won't get to drive it for 9 days so that sucks and I let my buddy use it when I left for the beach now its at home with the keys lock in it. Thanks for all the useful info in advance.
