2001 Silverado 2500HD shortbed 4X4. The truck has a 6.6 Duramax engine and a 5-speed Allison transmission. The has cold AC and the heater works. It has power windows locks and an after-market radio that is Bluetooth. You can play movies and music from a mini SD card or connect to your phone. The truck is an extended cab, and all 4 doors open, but the back doors are not full size. The truck runs great and has a lot of power. I bought it to tow a boat that I had but sold the boat and have been using the truck as a daily driver for the last couple of years. He truck has no EGR or DEF from the factory. I'm only selling it because I need a 4 door truck. I am selling and willing to trade for a 4 door truck of the same value. It can be a diesel (preferred) or gasoline. If interested, let me know. Not in a hurry to sell. This is my 1st diesel truck, and I love the power and durability. It doesn't have the EGR and the fuel injectors were replace 2 yrs ago along with the water pump. Truck runs great.
