Hey guys and gals, I am a newbie Duramax owner and have been lurking the site for a couple days. I just bought a used 07 GMC with the LMM motor. My father in law bought an 02 brand new in 02 and that when I knew I would have to have one! I literally got the truck two days ago and have been scouring the site for info. I have some experience with the trucks as my shop used to have an 04 for a few years. Ive been able to do some maintenance on both my in laws and the shops truck.So far the site has answered most of my questions but I am sure at some point my thread search will leave me hanging so I figured I should join up! I am also a member of the HAMB forum as well the CalGuns forum. If anyone is into firearms or hot rods and customs Take a peak at those two places.Lots of good stuff there.
