Why it stands out
The 2020 GMC Sierra 2500HD Denali is notable for its robust performance and a range of features that cater to both work and luxury needs. Offering a choice between a powerful gas V8 producing 401 horsepower and a turbo-diesel V8 generating 445 horsepower, the Sierra 2500HD excels in towing capacity, able to haul trailers up to 18,510 pounds when properly equipped. The truck's luxurious Denali trim brings high-end touches, including a full leather interior, advanced infotainment with Apple CarPlay and Android Auto, and thoughtful storage solutions.

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!!
