Is bringing the awning in an option? If I know it is going to rain, I bring my awning and slide in. If I get caught with unexpected rain, I will leave the slide out, unless there are high winds, but my awning comes in if there is any kind of wind or rain, wet or not.
My other unusual perspective #2 is because my RV is constantly waxed, water running down the side is non issue as watching the water beads run down would give us something to look at if we wanted to sit out under the awning in the rain
Observation:
Interesting how you LED lights under the awning are next to the RV wall. My LED light rollout with a tube and lights are on opposite of RV, you can extend/retract to have the lights point straight down, straight up or any angle you want.
