I agree with this fully. Despite a previous post, the WDH does not
allow you to pull heavier loads. The driveline, gearing, suspension, size of wheels/tires and brakes are designed by the manufacturer to carry and pull up to a maximum weight. It's the safety factor to be able to stop a load within a certain distance without the aid of trailer brakes if they fail. The WDH distributes weight and allows the load to go down the highway safely with a minimum of sway and loss of front-end steering.
