I installed 4 Rollertrol powered night blinds in my friends' Country Coach recently. 2 small ones on the end windows in the big slide and 2 larger ones on the side wall windows behind the table and his recliners.
They are 12 volt powered so I got power from the light fixtures in the cabinets in the slide. I took the bottoms out of both cabinets to get to the wiring. Not difficult to do.
They operate from a single remote, singly or all together.
The quality of the blinds is excellent and they were not difficult to install.
It is a hoot to hit the "all "up or down buttons and watch them all move at the same time!
They are not cheap, but the quality is very visible in every component.
They offer a manual version as well as day shades if that is your preference.
