Alternate to canvas slide toppers

[portscanner]

Has anyone seen the product put out by https://www.truetopperusa.com/ ? Instead of a canvas awning like cover on the awning, it is a device designed to sweep/sqeegee off the top of the slide as it is closed, then seal the top of the slide from weather when closed.

It looks very interesting to me. Looking for someone using it for their $0.02

Biggest issue is you lose the shading effect. We've had with and without toppers and without on a sunny day, the inside roof of the slide is much warmer without the topper.

I know they say it can be retrofit but removing the top flange is a larger project.

Also, how does the rubber roof of the slide hold up long term being scrapped every time the slide goes in and out.
