Sierra received a complete makeover in 2019. Consequently, the 2020 GMC Sierra 1500 returns this year with few changes. One of the big ones, though, is that the 15-view camera suite featuring transparent trailer recently introduced on the Sierra HD is now included in the optional Technology Package offered on SLT, AT4 and Denali grades.
Although Sierra and its cousin, the Chevrolet Silverado, share a lot of DNA, GMC elevates Sierra with upgraded interiors and a few extra standard features. It’s a work-capable truck with a higher-end pedigree.
