Mike's Notes
I personally inspected this Sierra Denali when it hit our Denver lot, and let me tell you — this is the trim to have if you want a luxury half-ton that still works like a truck. What jumped out at me first was the 6.2L V8; it makes this truck move in a way the standard 5.3 just doesn't, which matters when you're climbing Loveland Pass or passing slower traffic on I-70. The White Frost Tricoat paint still has serious depth to it, the 22-inch Denali wheels are clean, and the Cocoa/Dark Sand leather interior shows very light wear for a truck with 75K miles. I love that the CARFAX shows 19 service records with regular oil changes, a full brake job in 2022, transmission fluid flush, and a fresh alignment and coolant service in 2025 — this truck has been babied. Zero accidents, GMC Certified history, and with the Denali Ultimate Package (sunroof, power steps, trailer brake controller, MagneRide suspension) you're getting nearly $8K in options that make daily driving genuinely nicer. If you've been shopping loaded Denalis in Denver, come drive this one before it's gone.
Features and Benefits
• 6.2L EcoTec3 V8 (420 hp / 460 lb-ft) – Effortless power for towing trailers up to the mountains and confident passing at Colorado's high altitudes where lesser engines lose steam.
• 4WD with 2-Speed Autotrac Transfer Case – Handles Denver snowstorms, unplowed trailheads, and ski trips to A-Basin with rotary-dial simplicity.
• MagneRide Magnetic Ride Control – Adaptive shocks read the road 1,000 times per second, smoothing out rough Front Range pavement while keeping the truck planted when loaded.
• Denali Ultimate Package – A near-$8,000 factory upgrade bundle including the sunroof, 22-inch wheels, power steps, and trailer brake controller — all standard on this truck.
• Integrated Trailer Brake Controller – Safely tow your camper, boat, or side-by-side to the high country with smooth, dialed-in braking response.
• Heated Power-Folding Mirrors & LED Lighting – Clear visibility on dark, snowy Colorado mornings — mirrors defrost quickly and premium LEDs light up mountain backroads.
• Tri-Mode Power Retractable Running Boards – Easy step-in for passengers, then they tuck away for better ground clearance and aerodynamics on the highway.
• Bose Premium Audio with Subwoofer – Concert-quality sound for long road trips to Moab, Telluride, or across the plains.
• Spray-On Bed Liner with Denali Logo – Permanent, water-tight protection for hauling firewood, mountain bikes, or job-site gear without worrying about scratches.
