There’s no denying the Chevy had the measure of the more powerful Ford and Ram pickups, accelerating stronger uphill with a five-ton trailer and controlling its speed more effectively on descents with integrated exhaust and transmission braking. As for warranty length, the Silverado 2500HD and F-250 offer the same bumper-to-bumper terms, 3 years or 36,000 miles, though the Chevy boasts a slightly stronger 5-year/100,000-mile powertrain warranty to the F-250's 5-year/60,000 mile plan.
