Couple thoughts / Questions come to mind. You mention slop/play in the hitch when it is fully closed. Is it possible this is the wrong size coupler (2 5/8, vs 2)? If not that, any pictures of the underside of the coupler? In the closed position, it isn’t the bolt that should be holding the hitch on the ball. There is a little “shoe” that should slide in behind the ball and pinch it in place.
