This is my 2006 Chevrolet Silverado 2500 HD. This was my dream truck. It has the 6.6L LBZ Duramax Diesel and the 6-Speed Allison 1000 in it. It's a powerhouse. This truck was for sale in Opp, Alabama of all places with 280k on it. We bought it, and haven't looked back. Replaced a few front end components and a water pump, but no major issues. She has about 335k miles on her now, and she's still running the original engine and transmission, despite being tuned and having me drive her. I love this truck and will keep it until I die.
