For 2020, Chevrolet has completely re-designed the Silverado HD models to be bigger, badder and even more Heavy Duty, including greater payload, hauling & towing capacity. The full specs aren’t out yet but we know they will be available with 2 engines, one being an optional Duramax turbo-diesel V8. Larger mirrors, a taller driving position, and steps integrated into the rear bumper and forward corners of the bed are all features designed to make 5th wheel trailering easier.
