What is this? There is one at the front and one at the rear center of my 2014 RUSHMORE 5th wheel. They aren’t gray or black water vents. If my attempt at attaching a photo fails please let me know how to do it

There attic vents.

Thanks for the tip. I found them on Amazon. The lids on mine are are very brittle and need replacement. I just couldn’t think of what to search for. Again thanks.
