Ford leads the full size, half ton pick-up segment in terms of Payload and Towing Capacity when equipped with EcoBoost, 4x2 and the Heavy Duty (HD) Payload Package. However, you can't go very far with that full load on the standard 26 Gallon Fuel Tank :) I'd recommend making the beefier 36 Gallon Fuel Tank standard equipment for the HD Payload Package on 4x2 models. Thanks Ford!
