We were cleaning up from our trip today when we noticed a little moisture on the carpet inside the front cabinet (right side) of our AS. This is the cabinet on right front curve of the trailer. I quickly checked other places such as under bed, outside storage compartment, etc, etc. No other leaks were found. We had driven the past two days through some rain and wet roads, so I assume water was forced up through the front flooring edges.

I checked underneath and found where there were fasteners - I assume to hold the flooring - that had some loose sealing material. I barely touched these "globs" and they came loose. I took some pics to show the fasteners, and the globs that came off. The last image shows one with the material still on the fastener.

Questions: Could these be the source of the leak? Should these be re-caulked and with what? Any other recommendation to seal this area from road water leak. Should I put a bead of caulk around the complete line where the flooring sits on the metal channel?

Suggestions appreciated.
