Everything is new on the 2020 Chevrolet Silverado 3500HD. A new 6.6-liter V8 gas engine replaces the old 6.0-liter motor, and tow ratings have improved as a result. Additionally, it boasts stiffer frames and more modern technology throughout.
Furthermore, the heavy duty's truck sheetmetal is different than the light duty counterparts, aside from the roof. However, the interior remains much the same as the Silverado 1500, meaning the 3500HD uses the same subpar materials and conservative design.
