Mama - it's good to have options. Your A-Frame will allow you to use it in spaces other rvs may not allow due to space limitations. I carry a smaller lightweight canopy and a couple Costco beach umbrellas when I am solo camping without my large dogs. If the dogs go, then so does that commercial EZ Up. Haha
The Clam screen room and it's reviews online and by other A-Framers is on my list to purchase. Spouse wonders how many more canopies I will collect. Haha. I like the ease of set up that others report with the Clam. Since many of my trips are in the rain and wind, it seems a nice alternative to the heavy EZ Up.
