Check for proper tension on spring which rolls up the fabric. Check function of the "latch"'on the roller. Check the "key" fabric where the awning attaches to the roof.
Check that you can deploy and recover the awning safely a few times. The practice won't hurt and you will debug it.
Ensure the rivets parts are good,, that there is a good seal between roof and mount points.
Check the "locking" components are working properly...look along side the AS and ensure the ZipDee is not bent out of toward the AS.
Peace and Blessings..
