Oh, I have a cool idea, any chance you guys are planning on an antenna mount, for the center of the rear ROPS, but that has an arm that'll loop down under and up the backside of the honda P500 roof? So we can have a nice and high, centered antenna mount and still use a roof.
I realize it would be a bit more limited in your target audience, not all the P5's have honda roof, but still might fit some other models.
If you need a product tester...
