I am now part of the high mileage club. I own a 2005 GMC Sierra slt crew cab z71 truck. It has the v8 5.3l in it. Now for the amazing part. Orginal motor. Tranny went at 240k. Orginal rear end. Nothing but preventative maintance has been done to this truck. Second owner. I will always be a gm owner. It now has 302k on it and is very clean
