If the front panel is inadvertently left up when towing the strong winds can pull it loose allowing wind and rain to easily get in. If the panel has been retained by its operating spring it's an easy fix. But even if it is lost replacement is still simple.
As panels may take some time to be delivered relocating the rearward panel to the front needs to be done asap.
