We've just taken in a 2020 Gmc Sierra 1500 AT4 Crew Cab Pickup â" it's finished in Dark Sky Metallic, with a Jet Black with Kalahari accents Leather interior. With 103,817 miles, this AT4 mixes everyday comfort with weekend grit.
Power comes from the Duramax 3.0L Turbo-Diesel I6 (277 hp/460 lb-ft) matched to a 10-speed automatic and 4WD. Itâs rated at 22 MPG city and 26 MPG highway, so you cover serious ground without frequent stops.
With just one previous owner. good condition and a tidy cabin, you'll settle into the AT4âs front buckets and get supportive bolstering, Jet Black leather with Kalahari accents, and an upright, commanding view. On frosty mornings, heated and vented front bucket seats, and a heated steering wheel bring instant relief. On on muggy afternoons, those ventilated front seats keep you cool. Rear passengers ride happy with heated outboard seats, charge-only USBs, and rear air vents.
Confidence off-pavement comes standard. The Off-Road Suspension with a factory 2-inch lift, skid plates, Hill Descent Control, all-terrain tires, and a locking rear differential work together to find traction and smooth out ruts. Electric Power Steering keeps it easy to maneuver in town. LED reflector headlamps with signature DRLs and LED fog lamps light the way, while body-color bumpers and gloss-black accents give the AT4 a purposeful stance.
The Premium GMC Infotainment System with 8" touch screen brings Apple CarPlay and Android Auto, HD Radio and SiriusXM with 360L, and a 4G LTE Wi-Fi hotspot. A color Driver Information Center, steering-wheel audio controls, remote start, Keyless Open and Start, and an auto-dimming rearview mirror make busy days easier.
Tow days are simpler. The integrated trailer brake controller, Hitch Guidance with hitch view, and the in-vehicle Trailering App (checklists, maintenance reminders, electrical diagnostics) help you line up, roll out, and monitor your setup with confidence.
Bed duty is where the AT4 shines. The MultiPro Tailgate offers six clever load and access positionsâ"step up, reach in, load long items, or create a work surface in seconds. A spray-in bedliner, 12 fixed cargo tie-downs (rated at 500 lbs per corner), LED cargo lighting, a CornerStep rear bumper, and a 120-volt bed outlet turn the box into a real workspace.
Inside, a deep center console with cord management, SD reader, and USB ports keeps gear tidy, while rear seatback storage and full-width under-seat bins hold tools and weekend essentials.
Safety and stability are built in: 4-wheel ABS, StabiliTrak traction control, multiple airbags, a Tire Pressure Monitor, bright LED taillamps, and power-folding heated mirrors with perimeter lighting and memory.
If youâre after a do-it-all truck that commutes comfortably Monday through Friday, tows with confidence on Saturday, and finds trailheads on Sunday, this Sierra 1500 AT4 hits the sweet spot. Duramax diesel torque, 4WD with a factory lift, and genuinely useful tech make it an easy yes.

Nice truck
By froggy | on Sunday, December 06, 2020
I purchased this truck brand new and at 3900 miles I started to have a misfire. The warranty put a refurbished rebuilt engine in it. I was not aware that the warranty doesn't put new parts in just refurbished rebuilt parts. I traded in and lost my favorite blue truck. Not a fan of the whole process. Love the truck just not how the warranty went. I would not own another brand or model the 2020 is the nicest riding and looking. Just got a bad motor from the manufacture.… - 5.0
Great Truck
By Mel | on Sunday, April 25, 2021
I love it, I get compliments every where I go, and it apparently worth more than I paid for it brand new, a year and a half later. can't ask for much more than that.… - 5.0
Well done GM
By Tony | on Thursday, November 26, 2020
This truck has a 10 speed transmission that you can barely feel it shift. Traded in an F150 and test drove a similar equipped Ram. Although the Ram was nice, the styling of the GMC won me over, along with the tailgate! It also pulls my boat way better than the Ford, just smoother all around. The cabin is very quiet and the gas mileage is much better than V8 Ford. The cabin is super quiet and the ride is awesome. Love the adaptive cruise control too. The technology is fine and the screen is plenty big. Remember, you are driving this truck, not going to thr drive in! Most importantly, the controls are simple to use and Bose stereo sounds great! Oh, and I got it cheaper than the similar Ram too!…
