Insulating The Truck Camper Fridge Compartment Update Good

For my FnR, I found the fans work well in most conditions to keep it cool. But when hot direct sun hits the wall, it fights. So I got a reflective window shield and velcro it on the outside wall just below the vent and fans. It reflects the sun off the trailer and that does the trick. It doesn't hold heat in the venting space, but helps that space from being overheated by the sun. Easy to remove when not needed.
