Had this crazy idea of putting some extendable rails coming off the aero cap main rails fer a boat tail support.
To deploy them, I would pull the rails out and secure them.
Attach a framed boat tail and cover the frame with some flexible material (cloth) at that point and use my trailer light hook up fer any tail lights on the back end.
Move the license plate as needed.
I'll see what my brain can think up of...or any ideas y'all can come up with, too!
Thinking about doing the same thing fer extending my rear diffuser, too.
