The older coaches have a channel where the hooks for the curtain are. The pleated shades are on the hooks. Newer RVs have motorized shades on front on a mount. They are custom made for the coach.
To keep things cool when you are parked, I would get external windshield covers. They will keep the coach cooler since they stop the sun from coming in the coach. Personally, I really like my Magneshades. They are held on by strong magnets so you do not need to make holes in the coach. They are also very easy to take on and off. You do not need a ladder.
