My 5er uses a plastic cover at the corners where the trim comes together. They are starting to disintegrate from years of UV exposure. I am having trouble finding replacements at least in part because I don't know what to call them. I am not set up to post pictures so that is not an option.
I needed some for my 5er and couldn't find them so I printed a set. Mine look like this.

If you have a local RV place with a good parts dept., I would go talk with the fellow running that. Your description may produce results. I've been pleasantly surprised by this in the past.
