New Andersen WD hitch
A fellow camper bud showed me this. It's new and different. Anyone using one? Andersen WD hitches A U-tube video with the factory guy explaining it. You have to get past MR Truck doing his...

I think most (perhaps, all) of us agree that the Andersen hitch will cause significant forward thrust of the coupler assembly against the hitch ball. The big unknown, at least in my mind, is how a typical coupler will perform under this loading.
The following diagram is for a Shelby Industries Class III Posi-Lock Coupler. This coupler seems to be quite robust as regards its ability to transfer forward thrust to the ball.
Unfortunately the instructions for the Shelby Industries Class IV A-Frame Coupler do not present the same level of coupler detail. However, I would assume the Class IV coupler is even more robust than the Class III.
I have added my interpretation of how trailer forward thrust is transferred to the hitch ball.
