Most dependable truck i ever owned.

This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

Loved the Duramax Diesel and an incredible truck

Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

Exactly what I wanted and a lot more

Absolutely love everything about my new truck. Upgraded from an 05 to 15 and what an upgrade, smooth, quiet, better visibility, duramax needs DPF and EGR deleted but overall amazing

Just got it but look forward to the experience.

The truck rides great and looks really nice. I just bought it and have not had a chance to pull anything with it yet. I will be pulling a cattle trailer with it later this week and will see how it performs.

Great Truck

Good powerful truck for work & space for the family vacations. Seletable 4wd for the snowy days & nights, the Chrome Appearance package look with the All Terrain package stance is great.
