2011 chevy duramax 2500HD

Mechanically very good running pickup. Used to pull my 35 foot bumper pull camper and got up to 22 mpg with it. Would drive it absolutely anywhere. Truck has an extra leaf pack in the rear. On 18 inch wheels wrapped in 33s. I installed a aftermarket metal coolant reservoir as well as new brake rotors, calipers and pads in the front. Is 5 inch straight piped. Unsure of what kind of tune it has. Has a power steering leak im having troubles tracking down and the AC doesnt work. Might have wheel bearing going out due to the abs and traction control lights. No check engine light! Will come with an extra AC compressor, new belt, and a cp3 conversion kit. Will consider all offers and trades!
