Very nice AT-4 I purchased new in 2021, since then I have added a tonneau cover, running boards, Fuel wheels, Nitto tires, front 2 inch leveling kit, rear air bags with compressor and wireless remote. It has the 3.0 Duramax engine which is an amazing engine with great fuel mileage!! I have had the truck serviced at the dealer since new, no accidents and needs nothing! Open to offers and trades
