The best overall one-ton diesel is the 2011 GMC Sierra Denali 3500HD. This amazing truck took the top spot in five of six power contests. Like the Chevrolet Silverado 2500HD, its new ride and handling characteristics are excellent and its braking abilities were significantly better than its one-ton competitors. Interior fit and finish in its upscale trim were closer to the Ram and Ford trucks than any other category. We could tow with a Sierra Denali all day long and feel as confident driving it as it looks good on the road.
