Yes I replaced all three vents in my RV with fantastic vents when it was new. Then put one of the old vents into the RV I traded in.
The fantastic fans are very quiet compared to the bathroom fan it replaced, and more than three times the airflow. I covered them with Maxx air vents, and this gives less outside light inside, and protects the vent covers. They are now nearly 20 years old, no cracks or damage from trees, ect. And I can leave them open while driving, or in the rain.
I did find 12 volt power near my kitchen and rear bedroom vents, where there was not a factory installed fan (like the bathroom).
