Full-size heavy-duty American pickup trucks—specifically single-rear-wheel and dual-rear-wheel configurations of the Ford F-350 and F-450 Super Duty, Chevrolet Silverado 3500HD, and Ram 3500—offer the highest payload capacities in the consumer automotive market. Equipped with robust high-output diesel or gas engines, heavy-duty suspension systems, and dual-rear-wheel axles, these workhorses can safely carry thousands of pounds of payload in their beds.
