2004.5 LLY Chevrolet Silverado Duramax Diesel Crew Cab Short Box. It has all the bells and whistles on the exterior and some other minor mods such as: 5" Turbo back straight exhaust, Superchips four stage programmer, 2" lift blocks and front torsion bars turned up enough so the LT285/75R/16 Pro Comp Mud Terrian tires dont rub, weight bars for the front and the rear of the box, and plan to build traction bars for the front and rear. Other mods are in the future. Other than that i use my truck for pulling a 32' gooseneck trailer with hay or my 4320 john deere hotfarm pulling tractor around the midwest.
