Favorably reviewed: Owners rated the 2020 GMC Sierra 2500HD 4.86 / 5 stars.
73.3% of 2020 Sierra 2500HD models on CarGurus are accident free.
The 2020 GMC Sierra 2500HD offers multiple powertrain options, plenty of cargo space, and a luxurious Denali trim that enhances comfort and capability.
Why it stands out
The 2020 GMC Sierra 2500HD distinguishes itself with its robust performance and upscale features, particularly in the Denali trim, which is designed to provide a luxury experience in a heavy-duty truck. With powerful V8 engine options, including a diesel variant that delivers impressive torque, the Sierra 2500HD is built for serious towing and hauling tasks, capable of towing up to 18,510 pounds. The truck's spacious interior is complemented by advanced technology, such as a user-friendly infotainment system with Apple CarPlay and Android Auto. However, while the Denali trim offers a wealth of features, some users have noted that the interior materials do not fully meet luxury expectations, which may detract from its overall value. Despite this, the Sierra 2500HD remains a strong contender in the heavy-duty truck market, appealing to buyers who need both capability and comfort.

Looks great but a little pricey for the year. Even though it has low mileage. I would buy a newer truck.

The GMC 2500 HD is the truck for me. Like all the other major brands of trucks the price is in the same range. The diesel engine and 4x4 is about good as it gets. For work or play GMC is the way!!
