A later Q&A response (apologies for not pointing to it, I don't want to mess up my "last visited" time right now) clarified something about the volume constraints for the trailer hitch mounting hardware. The hardware obviously has to extend outside the BUMPER PERIMETER in order to fasten the hitch to the robot, since the hitch itself is defined to be on the outside of the perimeter. Inspection will verify that the hardware doesn't extend outside the hitch itself.
