When I was in Quartzsite this winter I had a torn topper awning
I called shadepro out of San Diego. I had Carefree of Colorado awnings of which they are a dealer
I ended up replacing 3 awning fabrics at a very reasonable price
I would try giving them a call, you can send them pictures and they may be able to help you
I had been dealing with a torn slide topper trying to contact Carefree at their factory through the whole covid time. They had shut down.
As a last gasp for help I called Shade Pro and they were our awning salvation. They matched our existing awning color and fabric, fabricated the replacement and actually came out and fixed it in the desert.
They will also send awnings and parts to you.
I cant say they can help you for sure but its definitely worth a shot
This is a number I keep in the coach now as their turn around time is great, you can get custom awning fabric in a week, maybe faster if you tell them its urgent
