2014 Ultimate One-Ton HD Challenge It's been almost four years since we last rounded up all three one-ton dualie competitors. In that time, all three have made significant upgrades in performance, passenger comfort and technology. For this test, all three trucks were one-ton 4x4 crew-cab dualies with 3.73:1 axle gears and maximum-output turbo-diesel engines. No price limits here; that's why we're calling this our Ultimate One-Ton Heavy-Duty Challenge.

Overview We've pitted these competitors because this segment has so much at stake. Ford's F-350 has a stronger Power Stroke engine and improved exhaust brake; GMC's Sierra 3500 HD has a new look, all-new interior and an upgraded exhaust brake; and the Ram 3500 HD offers a new front suspension and a multilevel exhaust brake. How do they compare? Overview
