What is the purpose of these?
I've attached a picture of the "vents" I am in question of. I've owned the trailer a little over 2 months so have not had to use the a/c yet but I have used the furnace and there is no air that comes out of these vents when it is on. What are their purpose? There is 10 total in my trailer (2020 outback 341rd) Thanks y'all
