I have owned this truck for over three years and it is my second Duramax. If you do proper maintenance these trucks will last a very long time. I have over 600,000 miles on my first Duramax and it's getting tired, and I just don't trust it real far anymore although I still drive it around the farm and into town. I drive my trucks very hard and I do not have time for breakdowns, so if you are looking for a hard working truck that will last look no further, Chevy has outdone themselves.
Towing power of the Duramax Allison combo, comfort, reliability.
The only thing I would change is to put the heated seat buttons in the center console instead of on the doors. Tired of reaching across the truck to turn on passenger seat for warm up.
