Multiple power outlets throughout—including 120-volt options in the bed and instrument panel—ensure your equipment stays charged.

This AT4 is equipped for serious towing with the dedicated Trailering Package. Hitch Guidance with integrated hitch view technology simplifies backing up with confidence, while the in-vehicle trailering app lets you monitor your trailer from your smartphone. The integrated trailer brake controller provides smooth, responsive stopping power for your load.

The truck's engineering emphasizes control and safety on any terrain. Off-road suspension geometry combined with hill descent control, auto-locking rear differential, and electronic stability control work together to keep you grounded on challenging ground. The 3.23 rear axle ratio balances power delivery with stability across varied driving conditions.

Exterior details reflect the AT4's purposeful design. Machined 18-inch alloy wheels sit beneath body-color bumpers and a color-keyed surround grille. Heated power mirrors, front fog lights, and fully automatic headlights with delay-off functionality add both capability and visibility. The spray-on bed liner, branded with the AT4 logo, protects your cargo investment while maintaining the truck's distinctive appearance.

Safety technology integrates seamlessly throughout. Dual front impact and side-impact airbags, 4-wheel disc ABS brakes, and occupant-sensing systems provide comprehensive protection. Electronic stability control and traction control work continuously to maintain stability, while the HD rear vision camera supports your situational awareness.
