First: we will discuss this question only as it pertains to non-commercial vehicles. Heavy-duty trucks are used by individuals every day to haul cargo for their small businesses, chores, farm work, and other duties, but it can be a bit challenging to find one that can handle a certain amount of weight without becoming difficult to handle, especially for newer drivers or those unfamiliar with driving larger vehicles.
Second: the automotive industry is never static. There are always upgrades, extras, and the like so that every year there are changes in the lineup for which truck can actually tow the most. That being said, there is a truck that stands out at the top, with a towing capacity of just over 31,000 pounds.
The Ford F-450 Super Duty comes with a 6.7L diesel engine, and utilizes a mill that was primarily designed for bigger commercial vehicles such as the Ford F-650 and Ford F-750. Previously, the title of biggest towing capacity was held by the Dodge Ram 3500, and it is speculated that the Ford F-450 Super Duty will lose its place as number one to either Dodge or Chevrolet when the next upgrade or model design occurs. For now, however, if you’re looking for the truck that has the highest haul capacity, Ford has laid its claim on that label.
