Lewiston GMC – Why Walla Walla, WA Drivers Love the 2026 GMC Sierra 1500’s MultiPro™ Tailgate and ProGrade® Trailering

For many pickup owners, the moments that matter most happen behind the tailgate and at the hitch. That’s why the 2026 GMC Sierra 1500’s MultiPro™ Tailgate and available ProGrade® Trailering System get so much attention from Walla Walla, WA drivers who split time between weekday work and weekend projects. Together, these two features turn the bed and hitch area into a smarter, safer, and more efficient workspace—without adding complexity. In everyday use, MultiPro™ delivers six clever functions that make loading, stepping up, reaching in, and securing cargo far easier than a traditional single-panel tailgate. Pair it with the available MultiPro Tailgate Audio System by KICKER and your jobsite or campsite becomes a mini hub for tunes, calls, and on-the-go podcasts.

The available ProGrade® Trailering System builds confidence from the moment you prepare to hook up. It layers in smart tools such as camera-guided hitch views, a Hitch Guidance overlay, and a Trailer Side Blind Zone alert when properly equipped. The In-Vehicle Trailering App lets you store custom trailer profiles, run pre-departure checklists, and monitor key statuses like trailer light tests or tire pressure sensors if equipped. Add the integrated trailer brake controller and the truck’s ABS can coordinate with compatible electric trailer brakes for smoother stops. The result is a towing experience that feels polished and predictable—exactly what you want when backing into tight spaces, navigating blind corners, or managing grades on rural roads.

• Six-function MultiPro™ Tailgate: Primary gate, load stop, full-width step, inner gate, inner load stop, and work surface boost utility all week long.
• Available ProGrade® Trailering System: Integrated camera views, Hitch Guidance, and custom trailer profiles streamline every hitch-up.
• In-Vehicle Trailering App: Checklists, status monitoring, and maintenance reminders help protect your time and your gear.
• Integrated Trailer Brake Controller: Calibrated brake force signaling assists compatible electric trailer brakes for composed deceleration.
• Available Camera Views: Expanded perspectives can reduce stress when backing to a coupler or surveying obstacles.

Underpinning these trailering and tailgate tools is a chassis and powertrain lineup that’s ready to work. The TurboMax™ engine’s 430 lb.-ft. of best-in-class standard torque helps you launch confidently with a utility trailer or boat in tow. For regular towing, the available Duramax® 3.0L Turbo-Diesel with a 10-speed automatic shines with torque-rich response on grades and long stretches. If your weekends involve steep forest roads or uneven surfaces, consider AT4 or AT4X with their off-road suspension hardware—AT4 brings a 2″ factory lift and Rancho® monotube shocks, while AT4X adds Multimatic® DSSV dampers and front and rear e-lockers. Together with the available two-speed Autotrac® transfer case, you can tailor traction and throttle response to the surface beneath your tires.

When loading up gear, the available CarbonPro® composite bed resists dents and corrosion and provides best-in-class short bed cargo volume. Add the available spray-on bedliner for added durability and LED bed lighting to keep your workspace visible after sundown. If you’re heading home late with the trailer, available Adaptive Cruise Control and a 15″ multicolor Head-Up Display can reduce fatigue by keeping the right information in view. And with OnStar® services including Automatic Crash Response, you gain added peace of mind on longer hauls.

For shoppers seeking a high-value truck that maximizes practicality without sacrificing comfort, these targeted features are a compelling reason to choose Sierra 1500. The cabin can be tailored for daily comfort—available heated and ventilated seats, a heated steering wheel, and Bose® premium audio—while the 13.4″ Premium GMC Infotainment System with Google built-in keeps navigation, playlists, and voice assistance a tap away. The net effect is a pickup that’s as easy to live with on a Tuesday as it is capable on a Saturday.
