Deja vu.

September 1, Schererville.

He did it again.
The now classic Mister Fix-it quick trick: water leaks in from above (the exact point of origin still a mystery) then is allowed to go out gently below, through a hole drilled for that purpose by Mister Fix-it, aka Fridman Torales, circus acrobat by day (mostly.)
My old quinta boasts a similar and quite unique RV feature, under the dinette, where water was accumulating into pools and mushrooms were growing into bouquets, deja vu all over again.
