Let me blow up one of the pics in the first link I gave you.
Somebody in your first thread mentioned the canvas pull strap. It would be located about here or could be tucked up under the roll. My Carefree didn't really have a pull strap
Zip-Dees can have a metal cover and a disengaging hook in about this position.
Zip-Dees can have wheels that unscrew in both these positions. They rotate 90 degrees out of the way to allow deployment when they are unscrewed.
My Argosy Carefree has something in this position but the condition of my Argo Carefree awning is pretty stone age. I don't have any of the above A, B or C items -- I have to use plastic cable ties around the main struts to travel. It's not purdy but it works.
