What is this vent for? I noticed yesterday when I was working on the water pump, I can see through the vent to the inside of the RV. This vent is completely open to that area. I noticed a couple of times when the fantastic fan was running I could feel warm air being pulled through the vent. Now I know why. I covered the back side of the grate with plastic film for now to stop the hot air from coming through. When its 105 outside definitely don't need any air leaks! But, what is this vent for?
