ac idea

Tabnero

it would be great if the ac exits under the 400 could be fitted with a louver system that you can open and close from inside the tab. That way it is closed going down dusty roads and open when your ready to use the AC. Which here in texas could be any day of the year

I was thinking the same thing @Tabnero, but I was thinking a cover on the outside that has a handle one would reach down and pull to open or expose the vents.  The dump valves on our old travel trailer were hidden behind the coroplast underbody, but there were two long “T-handle” rods that you would pull to open/close them.
