About This 2023 GMC Sierra 1500 AT4 Crew Cab

This 2023 GMC Sierra 1500 AT4 Crew Cab arrives in a sharp Black exterior finish that pairs perfectly with the AT4's signature off-road styling cues. With only 33,780 miles, this truck sits squarely in that sweet spot — past the break-in period, still well within its prime working years, and backed by remaining powertrain coverage. The 5 3/4-foot bed strikes the right balance for payload flexibility and daily maneuverability, making it equally at home hauling gear through the Yakima Valley or navigating tighter parking situations around town. The Crew Cab configuration means genuine rear-seat room for passengers, not just a token back row.

2023 GMC Sierra 1500 AT4 Performance and Engine

Under the hood sits GMC's 3.0-liter turbocharged inline-6 Duramax diesel engine — one of the most refined light-duty diesel powerplants available in a half-ton truck. This engine is known for delivering outstanding torque at low RPM, which translates to effortless towing and confident acceleration whether you're merging onto I-82 or climbing the grades heading toward White Pass. Paired with a 10-speed automatic transmission with overdrive, power delivery is smooth and precise across the full RPM range. Four-wheel drive is standard on the AT4, and this trim adds off-road-tuned suspension, skid plates, and a locking rear differential — hardware that earns its keep on unpaved Forest Service roads throughout the Cascades and the Yakima River Canyon.

GMC Sierra AT4 Features and Interior

The AT4 trim is GMC's off-road-focused package, but it doesn't ask you to sacrifice comfort to get there. Inside, expect leather-appointed seating, heated front seats, a premium infotainment display with wireless Apple CarPlay and Android Auto compatibility, and GMC's MultiPro tailgate — a genuinely useful innovation that transforms the tailgate into a step, a workstation, or a secondary inner gate. The Crew Cab layout provides generous legroom in both rows. Driver-assistance tech including forward collision alert, lane-keep assist, and a surround-view camera system rounds out a cab that feels more like a luxury SUV than a workhorse truck.

GMC Sierra 1500 Reliability and Ownership

The 2023 Sierra 1500 represents a generation of GMC trucks that has earned strong reliability marks from owners and automotive analysts alike. The 3.0 Duramax diesel in particular has developed a devoted following in the half-ton segment thanks to its durability, fuel efficiency compared to gasoline V8 alternatives, and the kind of low-end torque that makes real-world truck tasks feel effortless. Owners consistently report smooth highway cruising, impressive towing confidence, and lower fuel costs on long hauls. At 33,780 miles, this truck has barely begun its useful life — diesel engines in this class routinely reach well past 200,000 miles with proper maintenance. GMC's build quality on the T1 platform has been well-regarded, and parts and service are widely available throughout the region.

Frequently Asked Questions

Is the 2023 GMC Sierra 1500 AT4 a good buy?

Absolutely. The 2023 Sierra 1500 AT4 is one of the most well-rounded full-size trucks on the market. The AT4 trim adds genuine off-road hardware without stripping out the comfort and tech features buyers expect at this price point. Paired with the 3.0 Duramax diesel, it's a compelling package for towing, off-roading, and everyday use.

How many miles is too many for a used Sierra 1500?

33,780 miles is considered very low for a full-size truck, especially one with a diesel engine. Well-maintained Sierra 1500 trucks with the Duramax diesel routinely go 200,000 miles or more. At this mileage, you're getting a truck that's still essentially new while avoiding the steepest portion of new-vehicle depreciation.

What does the GMC Sierra AT4 trim include?

The AT4 trim includes off-road-tuned suspension, two-inch factory lift, front and rear skid plates, a locking rear differential, all-terrain tires, leather-appointed seating, heated front seats, the MultiPro tailgate, an 8-inch or larger infotainment screen with Apple CarPlay and Android Auto, and a full suite of driver safety technologies. It's GMC's adventure-ready trim that doesn't compromise on interior quality.

What is the towing capacity of the 2023 GMC Sierra 1500 with the 3.0 Duramax?

When properly equipped, the 2023 GMC Sierra 1500 with the 3.0-liter Duramax diesel is rated to tow up to approximately 9,100 pounds. That covers most fifth-wheel trailers, boats, and work trailers that Central Washington buyers typically haul.

Is a diesel Sierra 1500 more fuel-efficient than a gas version?

Yes — the 3.0 Duramax diesel delivers significantly better fuel economy than the gasoline V8 options, particularly on the highway and during towing. Owners commonly report 25+ MPG on open highway stretches, making the diesel a smart choice for buyers who put serious miles on their trucks or do regular long-distance hauling.
