In this video we take the a brand new 2021 Sierra 2500HD Denali Ultimate Duramax also equipped with the Black Diamond Edition package.
For 2021, the heavy-duty Sierra receives a host of new or improved trailer-assistance features. There's a new jack-knife alert that does what its name suggests and a trailer-length indicator that lets the driver know when nearby traffic might interfere with a connected trailer. The Multipro tailgate is now standard on the SLE trim level and there are three new paint colors. The Denali adds a newly standard high-definition 360-degree camera and a bed-view camera as well as a new Diamond Edition.
