Trim on front cab underneath - how to seal?
Going to attempt to recaulk stuff and want to re-seal the bottom trim on the front cab. Picture What is this stuff (the red down arrow)? I was thinking about using white PRO FLEX RV FLEXIBLE SE...

The two screws you see are only for end caps. As Don said, there's a vinyl insert in the middle of the channel that gets pulled out and there are more screws, one every few inches, underneath.
On my motorhome, I only sealed the leading edge of this piece and intentionally left the trailing edge unsealed. My theory (which may not be valid) was that this stood a chance of providing a sort of drain for any moisture that might get into the cabover structure, and the air flows and so forth are such that there's no practical way for water to work its way backwards into the seam. Rain would have to be falling up or the RV driving in reverse at great speeds during a downpour, neither of which I saw as likely events.
Underneath this trim piece the edge of the front sheet of filon or whatever overlaps the sheet on the bottom of the bunk board.
