Our 2021 2529RG has a Carefree Altitude power awning, I am assuming yours is the same. I did a quick search for a sunshade / fly but couldn't find one. On the Carefree website, you can call or email for information / help.
If you are successful finding a sunshade, please post your source of supply. I can't see where your home base is....maybe at a large RV shop there will be a vendor that makes them. When my brother was a full timer in Florida, there would be vendors at the bigger flea markets (Zephyrhills) that would custom make one.
Good luck on your quest!
