I just picked up a '96 Sierra 3500 with the 6.5TD in it with 130,000 on the clock. I'm new to diesels but I have had a little experience with them through some of my buds who have dodges. Basically I'm going to be using this truck for light hauling, and the occasional trailer with a car, it probably a little over kill for my use, but it was the nicest truck that I could find in my price range.
