Truck is clean, straight and solid. It has one of the most sought-after Duramax diesel engines. The high output LBZ (engine code "D") backed by the Allison 6 speed automatic transmission. It starts and runs fine. It is stock with the exception of a non-muffled oversized exhaust. The engine does not smoke, burn oil or drip. It has a block heater and winter high idle option. Over the last two and a half years it has averaged 19 - 20 MPG. It has the LT option package that includes the 7 speaker Bose sound system, auto climate control and 6 way heated leather. It comes with the canopy and the in bed/hide a ball 5th wheel hitch. The previous owner was very lax in maintenance, so I have invested over $16,000 to get it up to standard. I have done a lot of the big stuff like new tires, near total rebuild of front suspension, new calipers, pads and rotors on all four corners, new water pump, new power steering pump, new seals in front diff and new hydroboost/master cylinder.
