Why it stands out
The 2021 GMC Sierra 3500HD is a robust and highly capable heavy-duty truck, perfect for those needing serious hauling and towing capabilities. With a maximum towing capacity of up to 16,100 kilograms (35,500 pounds), thanks to its powerful options, the Sierra 3500HD stands out in its segment, especially when pitted against rivals like the Ford F-350. This model combines its work truck origins with improved luxury in its higher trims, notably the Denali version, which is geared towards those seeking both performance and comfort. Key features include impressive tech for towing and off-roading, making it versatile for both work and recreational use. However, potential buyers should be aware that higher trims can come with a hefty price tag, and the size of these trucks can make them cumbersome in tighter spaces.
