The tricky part to remove the awning fabric is the removal from the roller tube. On my Carefree awning one end cap has to be removed. That entails release of the spring pressure inside the tube. You can get hurt badly if you loose control of the spring pressure from the vise grip you need.
It is basically a two men job. I had mine redone by a repair shop for safety reasons.
If you want to tackle this yourself, I suggest you look up the manuf. website and check the removal and installation procedure.
