Finished in Onyx Black over Jet Black and showing 53,357 miles, this Crew Cab 4WD pairs GM's powerful 6.2L Eco Tec3 V8 with a 10-speed automatic transmission for a refined, confident full-size pickup. The 6.2L Eco Tec3 V8 is factory rated at 420 horsepower and 460 lb-ft of torque, giving this Sierra strong acceleration and the low-end muscle buyers want for towing, hauling, highway travel, and everyday driving. The 10-speed automatic keeps the V8 in its powerband while delivering smooth, responsive shifts, and four-wheel drive adds traction for Oregon winters, jobsite access, gravel roads, recreation, and changing weather. SLT trim moves the Sierra well beyond basic work-truck territory. The Jet Black cabin delivers an upscale environment with leather-appointed seating, heated front seats, power front-seat functionality, dual-zone automatic climate control, remote start, keyless access, and the comfort expected from GMC's premium truck positioning. Technology is equally important in a modern Sierra. The SLT provides GMC infotainment with smartphone integration, a driver information display, steering-wheel controls, multiple connectivity options, and useful trailering-oriented technology. Buyers should verify the exact optional packages, cameras, driver-assistance features, audio system, and trailering equipment installed on this VIN, as no VIN-specific factory window sticker was provided. The Crew Cab configuration gives passengers substantial rear-seat room and makes this truck equally useful for family transportation, road trips, work crews, or secure interior storage. GMC's pickup-bed design adds practical cargo capability, while the Sierra's bold grille and Onyx Black finish give this example a clean, upscale presence. With 53,357 miles, this 2020 Sierra offers an appealing balance between late-model equipment and used-truck value. The combination of the 6.2L V8, 10-speed automatic, 4WD, Crew Cab, and SLT trim is especially attractive for buyers who want real truck capability without giving up interior comfort. If towing is part of your plans, verify this truck's door-jamb payload certification, axle ratio, GVWR/GCWR, hitch equipment, trailering package, and specific conventional or other trailer ratings for your application. For shoppers comparing a Chevrolet Silverado 1500 LTZ, Ford F-150 Lariat, Ram 1500 Laramie, Toyota Tundra, or another premium full-size pickup, this Sierra SLT stands out with its 420-horsepower 6.2L V8, upscale cabin, Crew Cab versatility, and four-wheel-drive capability.
