2006 Aerolite cub 195

I have a 2000 Aerolite Cub 19, its a good trailer, my bunk door developed a leak at the top. I ended up rebuilding the entire bunk door but honestly wasn't too bad of a job. The Cub 19 pulls great behind my half ton, I have pulled it across multiple states without issue. The only complaint I have about the trailer is how warm the bunks can get in the Kansas sun, the fabric is a dark blue almost black and they soak up the heat. My AC will run almost all day when its in the 90's. I have considered making some type of divider out of heavy fabric to close off the front and rear bunks when we are not sleeping but haven't come up with anything that works well.
