This 2005 GMC TopKick C4500 Pickup shows approximately 20,200 miles and is powered by a 6.6-liter Duramax turbodiesel V8 paired with an Allison 5-speed automatic transmission and 4-wheel drive. It features numerous modifications including a Sierra-sourced pickup bed, leather upholstery, a power reclining rear bench seat, and a fuel transfer tank, along with a dually rear axle and air brakes. The vehicle has a clean Carfax report showing one owner since new, though it does have some scratches on the hood, weathered exterior trim, and corrosion on underbody components.
