Chevrolet Silverado MD pickup trucks utilize a platform that was jointly developed by Navistar and General Motors.
To clarify, the Silverado 4500, 5500, and 6500 do not ride on the T1 platform or K2 platform, which are utilized by third and fourth-generation Silverado 1500, 2500, and 3500 models, respectively.

The 2021 Silverado should become available by the end of Q3 2020.
Beyond 2021
We expect the Silverado Medium Duty pickup trucks to remain in production for the foreseeable future, with mild updates and enhancements along the way. The Chevrolet Express and GMC Savana are great examples of this, as they have remained more or less unchanged for the past decade.
