Does your Minnie Plus have slide topper rails?

I have a 2019 27rbds and noticed rails installed above both my slides. There is no other evidence of slide toppers (no holes, nothing on the slides) but wondered if I wanted to install toppers, what brand is this rail intended for? Does anyone else have rails pre-installed?

I’ve Winnebago instinct 28rbds, which is basically the same as yours. I had a slide topper installed on the large rear slide. I was told by the installer that a topper wouldn’t really fit, or at least, have no slope on the kitchen slide.
