Problem: Right now I do not have my AC installed so I keep a tight fitting piece of foam insulation stuck in the vent hole to keep the cold air out of trailer. Trailer sitting....if the wind is blowing hard enough in the right direction it can pop the foam out....since that can occur, the problem I am concerned about is when driving down the road and it is raining, that some rain will get in thru that vent. So far, all my trips I have taken since installing the vent, I have had no rain to test that theory.

Solution: My idea is to cover the vent panel on outside of trailer with plexiglass panel or maybe a rock guard panel and fasten it with the twist lock fasteners to make it easy to get on and off. I would either 3M super duper tape or glue the fasteners to the vent frame so that I don't drill additional holes into the trailer. In addition I was thinking of maybe also installing a rain/wind guard like I have on my truck windows but run it up and down the left side of trailer vent to maybe force the air around the vent when traveling down road as extra insurance of rain not getting in. I considered the super duty velcro which is a great idea; however, I have nerve and muscle issues in my arms and hands and don't have a great deal of strength to wrestle the velcro to get cover off hence the twist lock idea.
Suggestions, ideas, would be welcomed as to how to remedy this situation without a lot of headache.
