AC ducting question

[working on it]

For the past two years, I've been explaining why and how I put my A/C inside the galley, and not on a slide-out, or (as shown in this thread) completely outside the trailer. Shadow Catcher and Bobhenry show theirs sitting on the ground, and mikerueve shows his on an outdoor stand. My question is this: what prevents the "normally located inside the abode" electrical/electronic controls, on the face of the windowshaker, from damage if a sudden downpour saturates them. To my best knowledge, at least on my home units, they are not potted/waterproofed against the elements. Looks like Shadow Catcher built a cover over that area (for protection?), but did you other guys do something similar? And, do you have spare hoses handy, in case of inadvertent damage or mis-adventure (my park power source was unplugged by neighboring campers, so could the hoses) by passersby? My system was hard to perfect; the system shown here looks simpler, and possibly more a universal solution than mine, so what drawbacks (if any) did you have to overcome?

When you think about it a window shaker is water proof from the point where it intersects the window. What I found in my very simple controls is that once removed there was nothing left that could not get wet. The fan motor is on the wet side and sealed. I did leave the fan speed switch in place but it could easily have been moved into the control box as well.

The "sudden downpour" question is one that does have me worried. For now, the only plan I have in place would be to grab my trusty roll of duct tape and a piece of clear plastic that I have in my front box and quickly seal any areas of the control panel that have to do with the controls. I also have a couple of pieces of tarp available that I could use to cover it if necessary. I keep two of them. One to drape over the roof vent so that I can keep it open. The other is to protect the AC if necessary. Usually, if it's raining, or about to, the temps have cooled enough to not need the AC anyways.
