What prevents water from getting through the vent openings into the ac area?
I am thinking about a condition where you are driving in a hard rain and/or where a strong wind is driving rain water towards the vent openings.
I really haven't had any issue with that. This is the same vent used on almost all RV's with Gas Refrigerators... Water has to come up from underneath to get in. The drip edge prevents water from running down the surface from the roof and splashing in on the inset ridges... I did get some splashing before I did that.
What I did do was make that area pretty water friendly. Any water gets in, it will be on flooring materials which I lined the shelf with. I caulked really well so water could not find its way into the walls and will drain back out. If you look real close at the picture, you will see what I mean.
I have been in some real good downpours on the road and have not had any water get in. I just had everything apart when I put in this new AC.. No signs of water from the last year in service.
