Looks just like the vent for my swamp cooler outlet in my garage. Might want to try looking for a replacement at a swamp cooler parts house. That's where I found mine. The vent cover I have is 22x22 inches and has slats behind the top slats in order to direct the flow.
Just an idea.
Hey Guys,
This is the vent panel on the outside of the cabin house on my 2005 Mainship 400. It vents the fridge cabinet. As you can see, it has seen better days. Any idea where I could find a replacement?
Thanks.
