2021 Silverado 1500 diesel 4x4 tows well, lots of torque can tow 9000 lb trailer. Loaded right for me as an RST. Fastest 1/2 diesel going up hill. Will it be the lone survivor of the 1/2 ton diesels when all the electric trucks come to market? Fun, fuel mileage enough for a daily driver and one of best fuel mileage towing in a 1/2 ton. Took a different route thru the mountains. 2021 chevy silverado, 2021 chevy 1500 duramax
