Lewiston GMC – Why Colfax, WA Drivers Choose the 2026 GMC Sierra 3500 HD Denali for Confident Towing and Everyday Refinement

For drivers around Colfax, WA who demand strength without sacrificing sophistication, the 2026 GMC Sierra 3500 HD Denali delivers a rare combination of torque, trailering intelligence, and premium comfort. It is designed for heavy-duty work with a 6.6L V8 gas engine or available Duramax 6.6L Turbo-Diesel V8, both paired to a 10-speed automatic transmission for assured power delivery on grades and highways alike. Denali’s distinctive exterior presence — complete with 20-inch Ultra-Bright machined aluminum wheels with bright chrome inserts — signals capability, while the cabin’s Denali-exclusive authentic wood, patterned aluminum trim, and Forge perforated leather seating surfaces create a space that makes long days feel more manageable. Up to 14 available camera views, including Transparent Trailer View, HD Surround Vision, and hitch guidance tools, turn complex maneuvers into confident motions. When the week ends, Denali’s quiet ride and supportive seats help you arrive refreshed and ready for more.

Technology in the Denali trim works like a partner. The 13.4-inch diagonal center touchscreen and 12.3-inch diagonal digital Driver Information Center present key data clearly, and the In-Vehicle Trailering App streamlines checklists, maintenance reminders, and trailer profiles. Add the available Rear Camera Mirror to keep a wide, unobstructed digital view when your bed is full or a tall trailer blocks the conventional mirror. Towing control benefits from the Traction Select System’s Tow/Haul mode, while the MultiPro™ Tailgate brings unmatched flexibility for loading, staging, and accessing the bed. Pair it with the available MultiPro Tailgate Audio System by Kicker® to bring sound wherever the day takes you — perfect for jobsite briefings or campsite evenings.

• Towing confidence: Up to 14 available camera views with Transparent Trailer View simplify backing, lane changes, and tight turns.
• Premium comfort: 12-way heated and ventilated power front seats and Denali-exclusive materials reduce fatigue on long drives.
• Trailering tools: ProGrade® Trailering features and the In-Vehicle Trailering App help you manage multiple trailers and maintenance.
• Versatile bed access: MultiPro™ Tailgate offers multiple configurations for easier loading, unloading, and on-site staging.
• Diesel strength: The available Duramax 6.6L Turbo-Diesel V8 pairs refined power with confident long-haul performance.

For shoppers cross-shopping other heavy-duty trucks, Denali’s camera technology is a standout. Transparent Trailer View alone can transform how you tow by allowing a virtual look through a compatible trailer to help reveal approaching traffic and curbs in your blind zone. Add HD Surround Vision to stitch together multiple camera angles as a top-down view for precision in tight spaces. On the comfort front, heated and ventilated front seats, refined materials, and noise isolation keep you focused and composed, even after a full day on the road.

At Lewiston Chevrolet GMC — serving Clarkston, Colfax, and Orofino — our team can help configure a Denali tailored to your specific trailering needs. Whether you want to profile multiple trailers in the app, add the MultiPro™ Tailgate Audio System by Kicker®, or evaluate the benefits of the available Duramax diesel for your routes, we will walk you through every option. If you frequently navigate gravel or unpaved access roads, consider stepping up to features that bolster underbody protection and camera coverage to make those final few miles just as confident as the highway stretch.
