Our 2018 Revel came equipped with the Winnebago screens that didn't function well. We finally bit the bullet and bought a set of Rolef screens for $1600, and installed them ourselves. The installation was not particularly difficult, but it requires patience, accuracy, and watching the Rolef videos on YouTube over & over (no instructions come with the screens).
Here's a picture of one of the original screens.
And here are the new ones. Very flexible and functional, well worth the time & money.
