These aren't mine. I was looking for something like them to answer a post on another forum. But they are an excellent description. In it, a 3025# trailer starts with 450# tongue weight. After the WD hitch installed, the load on the ball increases to 1039#, but the net weight on the tow vehicle decreases to 300# because of the load transmitted to the trailer from the tow vehicle through the WD bars. The load on the trailer axle increases a corresponding 150#.
