When we needed to replace the awning fabric on a previous trailer, I checked prices on replacements. It was a manual Dometic. Our local Camping World had a sale where they charged $49 to install new OEM fabric. All in all, it was about $15 more for them to do it than me order it, pay for shipping, and then install it.
I took the trailer in and 2 hours later, had a new awning.
You might want to check to see if they still do something like that.
