That is the Keder rail insert. We still have ours in place. We have a CS with different trim. The reference above was for a CS not an S nor the keder insert.
We took ours out and threw it in the trash.😂 it didn't match the cute aesthetic of our trailer. Are we supposed to keep it? It definitely got in the way when I was trying to put up my party lights and sunshade. There's no way I would be taking it off and putting it on and taking it off and putting it on. 5 1/2 years with no issues.

When camping, we live behind the 'CS and not along side. We don't use the keder rail. With your regular 320, you probably live on the side of your trailer. No worries, we each use our trailers differently. If I was using the keder rail, I would trash the filler too.

I just replaced all of mine last week. It does look better with new material.
I was hoping to find an LED light cable the right size but never did.
