About This 2020 Chevrolet Silverado 2500HD Crew Cab LT

At 84,970 miles, this Silverado 2500HD sits in a comfortable sweet spot for a diesel heavy-duty truck. Diesel engines are built for the long haul — many Duramax-powered trucks are still running strong well past 200,000 miles with proper maintenance — which means this truck has a tremendous amount of useful life ahead of it. The Crew Cab configuration gives you a full four-door layout with rear-seat room that rivals many SUVs, making it just as family-friendly as it is job-site ready. The 6.5-foot bed strikes a great balance between payload capacity and maneuverability around town and on the highway.

2020 Chevrolet Silverado 2500HD Performance and Engine

Under the hood sits Chevrolet's legendary 6.6-liter Duramax Turbo Diesel V8, paired with a 10-speed Allison automatic transmission — widely regarded as one of the best heavy-duty transmission pairings in the industry. The Duramax produces 445 horsepower and 910 lb-ft of torque in this generation, giving you the muscle to tow up to 18,500 pounds when properly equipped. The Allison transmission is known for its durability, smooth shifting under load, and exceptional longevity. Four-wheel drive is ready when you need it — whether that's hauling equipment to a job site in the rain or heading out to the desert or mountains on the weekend.

The 2020 Silverado 2500HD LT also includes a suite of safety features including a rear vision camera, trailer sway control, automatic locking rear differential availability, and StabiliTrak electronic stability control. These aren't just checkbox features — when you're towing heavy loads on Southern California freeways, these systems matter.

Chevrolet Silverado 2500HD Reliability and Ownership

The Duramax Diesel and Allison transmission combination has earned a rock-solid reputation in the truck community.

The 2020 model year brought a fully redesigned platform with improved chassis rigidity, better noise insulation in the cab, and refined suspension tuning. Real-world diesel fuel economy for this truck typically lands in the 15-18 MPG range on the highway — respectable for a truck capable of towing nearly 18,000 pounds. Common maintenance items to stay on top of include diesel exhaust fluid (DEF), fuel filter changes, and regular oil intervals, all of which are well-documented and affordable to maintain.
