I think I saw this in a post somewhere - the suggestion that you could build an aero-optimized boattail that would attach to a hitch. So rather than drill and screw to the sheet metal, it mounts and dismounts. And if you get pulled over you say "It's a luggage carrier". Which it will be, because it has a big space inside and a hinged or removable access panel.

Or maybe I thought of it - - who knows. Beyond my modding skills, but it might be a workable idea. Needs a full set of working lights and a license plate mounting location.
