Overview
Reviews
FAQs
The GMC Sierra 1500 is a spacious and capable pickup. It is offered in a number of trims providing a wide array of creature comforts. While GMC might be more sooner associated with the chrome-clad Denali variants, the Sierra is also available in more outdoorsy trims, such as the AT4. Designed as a sort of the anti-Denali, the AT4 is designed to get muddy. It features a 2-inch lift, Rancho shocks, upgraded underbody skid plates, an Auto-Trap two-speed transfer case, and a locking rear differential. The AT4 is not without niceties, as it receives a unique black interior with Kalahari accents and a host of creature comforts. The AT4 trim was introduced with the redesigned Sierra 1500 in 2019 and has continued through the 1500’s 2022 model year update.

The truck had all the features I wanted and the price was in-line, or better with others in my search.
