Hello all, first just let me say that I'm a new member, and this is my first post. I just ordered a 2001. 5 2500QC auto. Ive been looking through all the forums for quite some time to get advice on what to order. I want to thank everybody for the wealth of info I have received. I do have one question though, my dealer called and said my truck was in a D1 status, how do I track the truck through DC? I know I can do it with the rail system. And also, how can I tell which plant the truck will be built at and what day? Thanks Again
