Vehicle Overview

Versatile SUV with modern tech and comfort

Introducing the 2026 AT4 in striking Frostbite White — rugged capability wrapped in premium comfort. With standard 4WD, locking differential, stability and traction control plus 10.1" of ground clearance on LT275/65R20 tires, this truck delivers confident performance where the pavement ends. Step inside to heated/leather-trimmed, cooled front seats with power adjust and lumbar, a heated leather steering wheel, navigation and a power sunroof — all accessible via keyless entry and remote start with climate control. Safety is rock-solid too: multiple airbags, ABS and electronic parking aid, seating for six, a full-size spare and industry-leading warranties. Stop by today and let me show you how the AT4 blends capability and luxury.
