Installing new vinyl trim inserts, caulk or no caulk?

So I replaced/repaired my roof this summer on our hybrid travel trailer, and as part of that headache, I replaced some of my aluminum trim pieces along with all new white vinyl inserts and #10 screws...

I installed new insert at the roof. I use sealant a the very ends and also in each screw hole. I also upgraded to stainless steel screws.

Here's a few videos I did on the project:

When installing vertical sections of trim, you don't want to seal the bottom. Photo in the post above mine shows that quite well.
