I have owned this truck for 3 years now and have put over 75,000 miles on it since I drove it off the lot. The Duramax/Allison combo is unbeatable in todays truck market. I have not had a single issue with this truck. I have 3 friends with the exact same model with no problems either. It pulls our 5th wheels with ease and the manual electronic shifting is great for going down steep grades. I just replaced my original set of tires at 70,000! Other people have complained about MPG, but I average 16.6 MPG! I highly recommend anyone looking at this model year to buy it!
Reliability, manual electronic gear shift, sound system is great for stock, comfortable leather seats, plenty of power.
