So, your worry is that the coupler socket is too close to the frame, and when you make turns the hitch head will strike the frame, correct? I think this would be easy to test when you get to the dealership. Just have a couple of guys hold the head in place (most easily done if the ball is mounted, at least loosely, and inserted in the socket) and then swing the head from side to side simulating a turn. If something is going to hit, it should be evident right away. That way they don't need to go through with an installation if there's a problem.
