2015 Silverado 2500 GAS 4x4. This has the smaller back doors that open normally. 220k miles and climbing. Daily driven. Has a light for o2 sensor. I have one just haven't put it on. Doesnt affect anything. New tires last fall. Doesnt leak or burn anything. No rattles squeaks or shakes. Goes down the highway smooth and quiet. Never had a hitch in the bed. Was previously a fleet truck used for hauling people and tools in Minnesota. Has rocker rust as seen in photos. Back passenger door seems to think it's open all the time and the window works when it wants to. For sale not on sale. Please no trades.
