I think we just have a terminology problem. My point is the weight doesn't disappear or is attached differently just because you hookup a WDH. The WDW is designed to push up not down on the hitch, but to do that the force still goes through the hitch. There are no other attachment points to the truck. If you are worried about hitch strength, a WDH isn't going to fix it. The lever arm is still 4 feet.
Then why are the hitch and the extension both rated for more weight WITH a WDH ?
No , the weight doesn't disappear , It is distributed differently through the attachment point . The upward force is subtracted from the downward force to lessen the downward reaction at that point . Then it is transferred through the frames to the front axle of the tow vehicle and the trailer axles .
