WDH - I think I understand
OK a WDH distributes the hitch weight across three points (theoretically) - Front axle back axle, TT axle as opposed to simply at the hitch point. So for simple math a hitch weight of 900# would ...

Think of it this way in simple terms. The car is a seesaw and it pivots on the rear axle. If you hang too much weight on the short end or the end with the hitch, it will lift the long end (front end of car/truck). The arms of the WDH simply help push the vehicles front end back down so you don't compromise your steering. The steer tires need a certain amount of weight to a properly steer/control the vehicle.
Have you ever watched the front wheels of a farm tractor or tractor pull come off the ground? Pretty hard for them to steer the load. They get around this by adding weights to the front of the tractor. A farm tractor can also steer by separate brake controls on the right or left side of the drive axle.
When we tow a heavy trailer, the WDH uses the load bars to push the front end back down to restore steering. While the bars pull down on the trailers "A frame" the weight added to the trailer is not as proportional as your example. The hitch weight is still carried on the hitch and tow vehicle.
