Have owned this 4wd truck for 20 years and it’s always been parked under cover so body and box in good condition. 6.6 litre Duramax diesel engine with Allison transmission. Long bed with liner, full crew cab, brand new windshield, new tires, all gauges work, clean throughout. Everything in good working condition with no work required on your part. Have all maintenance records dating back to 2005 when purchased. Very reliable truck that’s set up for trailer hauling including working electric brake controller. Also set up and wired for camper with tie downs. These powerful trucks are very reliable if properly maintained and this truck has been very well maintained throughout its life. I expect a long life yet to come for this quality truck.
