180k on mine, purchased with 150kOk so I just bought a Yukon that has 165k on it and it runs great! Just curious how many miles you guys have on your trucks and how strong the motors still are....mostly concerned about the 5.3L motor cause that's what I have.
doesn't burn any oil, I run Mobil1 0W20, and a K&N drop in filter, and it runs like a brand new truck.
