Anderson Ultimate and aluminum truck bed compatibility

On the B&W, the weight is not carried by the bed floor. It is carried by the square bar that inserts into the square gooseneck ball hole. The bar mounts into the gooseneck hitch the same way the ball mounts into it. The bar bottoms out on the bottom of the hole, just as the ball bottoms out in the hole, and is pinned in place by the sliding pin that also locates the ball.
