The 2020 Silverado sees deletion of the "Oakwood Metallic" exterior paint color. Major additions are new vertical trailering mirrors, which include power adjustability, as well as power-folding and power-extension capabilities. Adaptive Cruise control is optional on the LTZ and High Country trim levels, and SiriusXM 360L capability is available on LT and higher trims. Silverado 1500s lose the keyless access buttons on the rear doors.
