spare

The rear portion of the pan could become a diffuser which would cut drag a smidge more.If there was still room for the spare then a hinged panel is a good move.
On my Dodge,I created a closet for the spare to slide into.The floor of it creates the diffuser.
On the Toyota,I keep the spare in the bed.
