Replacing the whole awning or just the fabric?
I just replaced the fabric on our TT. 15' x 8' for a manual awning. The fabric was $120 on ebay and was about a 2.5 hour job for me and a 1 hour job for two friends who helped hang it. It was just as easy as the youtube videos make it seem.
BTW, the local service place wanted $600 to replace it.
