Welcome to the forum.
There are tons of awning replacement videos out there.
The first video is a good overview for an LCI electric awning (not sure what brand your 2008 has.) The second video is for a Dometic/A&E awning. I would encourage you to watch several others, in particular if yours has the tension arm so you can learn how to safely handle unwinding and re-tensioning. I found one video "Fastest RV Awning fabric replacement" and the tech said to wind it 14 revolutions.
