Covering the A/C and door windows on our 2021 T@G

Nonarocks

Made the cover removable.  Hung a dowling on hooks and made a casing at the top of cover.  Velcro is all the way around.  It helps with remotes, cards and movie snacks!  The AC is not used very often, but still is useful

I made a similar design for my porthole windows. I used a double layer of insulated foam, similar to Reflectix but stiffer. I also added a nylon webbing handle, which makes it easy to pop out of the window. They’re completely light blocking, allowing for better sleep.
