Water is not only the killer of RV's but homes as it will always find a path to enter both. There are ways to limit damage from water by during regular inspections of all seals-windows-and even what water got in when closing the slides.
We have closed the slides in rain storms and we check and clean up all water that got past the seals, that includes what is on the side of the slides.
Again check your windows as that maybe the most likely area.
