The cabin reflects premium attention to detail with color-keyed carpeting, floor-mounted center console, and heating elements throughout.
The EcoTec3 engine operates intelligently through 17 different fuel-saving patterns, adapting between 2 and 8 cylinders based on driving demand. This sophisticated approach balances the raw power you need for towing and hauling with efficiency considerations for daily driving. With 44,584 miles, this truck has been maintained carefully and remains well within its prime operational years.
Trailering capability is comprehensively supported through the integrated trailer brake controller, hitch guidance system with in-vehicle app integration, and red recovery hooks.

Temperature control zones keep occupants comfortable regardless of conditions, while the available 4G LTE creates a connected experience on the road.
