I believe that it was because of water running down the side of the slide when extended and then because there was no drip edge, it would run underneath the slide floor and found its way into the edge of the OSB floor. Similar wicking action along the thread of every screw and bolt that went into the Darco wrap on the lower frame of the outer slide wall. Once the water wicked in, the Darco trapped it there. That's why I eliminated the Darco completely and coated the wood with undercoater.

What surprised me was the fact (We replace slideout floors a lot, poor design) quote from RV repair center. They purchase full 12' sections of plywood from Elkhart IN a dozen at a time.
None of these slides have a drip edge along the lower edge of their side walls, so it's not a question of whether they will leak, but rather a question of when....
