The power sunroof floods the interior with light, while the Technology Package brings advanced driver assistance features including adaptive cruise control, lane departure warning, and automatic emergency braking.

The multicolor display puts critical information exactly where you need it without distraction.

Safety and visibility are paramount on this truck. The HD surround vision system, automatic high-beam headlights, and trailer side blind zone alert keep you aware of your surroundings. Power-retractable assist steps with integrated LED lighting make entry and exit easier while adding functional elegance.

Every detail reflects AT4 craftsmanship. The 20-inch high-gloss black aluminum wheels, gloss black header grille, and smoked amber roof marker lamps combine form with function. The winter grille cover, rear wheelhouse liners, and power-retractable steps are designed for serious work in serious conditions.
