GMC Sierra 2500 Duramax 4x4

2015 GMC Sierra 2500HD WT Duramax 4x4. Has a lot of recent mechanical upgrades, new engine with paperwork 14k miles ago, new fuel system, CP3 swap, head studs, lift pump, 20 inch vision wheels, tires are about half tread, Kryptonite upper control arms with new bushings and ball joints, B&W gooseneck hitch. We do not have paperwork on the CP3 swap and head studs but you can physically see them under the hood. Clearly this is not a show truck, it needs a good cleaning, has dings, dents, scratches, Texas truck so no rust. Solid truck mechanically, ready to go to work. Clean and clear title.
