The truck's interior reflects the AT4's premium positioning. Perforated leather-appointed front seats offer both heated and ventilated functionality, allowing you to maintain comfort regardless of season. The 10-way power driver seat with lumbar support ensures proper positioning for all-day driving. The multicolor 15" head-up display and 8" digital driver information center keep critical data in your line of sight without distraction.
Technology integration is comprehensive. The GMC infotainment system supports Apple CarPlay and Android Auto, while SiriusXM satellite radio and 4G LTE Wi-Fi hotspot capability keep you informed and connected. Blind spot warning, lane departure warning with lane keep assist, and rear traffic alert provide additional awareness during daily use. Automatic emergency braking and front pedestrian braking enhance safety across various driving scenarios.
Trailering capability is built into this Sierra. The integrated trailer brake controller, trailer tire pressure monitor system, and hitch guidance with hitch view make towing intuitive and secure. Red recovery hooks and the ProGrade trailering system demonstrate GMC's attention to truck ownership needs. The bed view camera and multiple camera angles provide situational awareness whether you're navigating tight spaces or backing up a trailer.
Performance enhancements reflect careful specification. The dealer-installed performance air intake system and cat-back performance exhaust optimize engine efficiency and response. Off-road suspension geometry supports both highway stability and rough terrain capability. The 3.23 rear axle ratio balances towing capacity with everyday usability.
This truck has been well cared for as a local trade-in by a non-smoker. Its 70,630 miles represent typical annual usage, and the vehicle qualifies for further inspection. The AT4 trim represents a thoughtful balance between capability and comfort, designed for owners who value both function and appointment quality in their daily driver.
