The GMC Sierra 1500 is not a new vehicle for you in 2021, despite the possibility that it may be. 

The GMC Sierra hasn't undergone many improvements for the current model year, so its shortcomings from 2020 remain.

What’s new for the 2021 GMC Sierra 1500?  At this moment, the GMC Sierra 1500 and Chevrolet Silverado 1500 are almost identical. But they aren't the same. 

Even though they have distinct badges, they are looking and acting more and more alike.

The Chevy Silverado now has every feature that distinguished the GMC Sierra. 

For instance, the Silverado now has the Multi-Pro tailgate, which was previously only available on the Sierra.

The 2021 GMC Sierra Denali is an exception, according to AutoBlog. Its variable ride suspension, which is a GMC unique, substantially enhances the ride and handling. 

However, while looking at lower-trim cars, you must choose between the Sierra and Silverado.

2021 GMC Sierra trailering upgrades  The addition of trailering technology to the 2021 GMC Sierra is the most important upgrade. 

With the addition of a trailer length indication, jackknife alarm, trailer backup recommendations, 

and a superior camera with a rear side view and cargo bed feed, changing lanes is now safer.

The Sierra has cut the cost by $995 if you want the diesel, just like the Silverado. 

In addition, the trailer's weight capacity has been raised to 9,300 lbs.
