My 1st diesel and I LOVE IT!!! The Duramax is a fantastic engine. Bought with 162,756 on the clock and she runs as new if not better. I just drove across the USA with ZERO issues, this is a keeper machine for me.

I bought this 3500 last week with a lot of highway miles but it runs like new. I am amazed at the power the 6.6 Duramax Diesel engine has, coupled with the Allison tranny, WOW! Best truck I have ever owned.

1 Bad ASS truck, 160,000. Best for the money.
