This doesn't help you but had ours made here in FL. They're an independent couple from Canada. Ours is 19 x 8 done in black and cost $90. It slides into the awning track and has about 8 eyelets along the bottom to attach it with bungee cords to the ground. I've seen other businesses that have these at RV shows but for many more $$$$$. The fellas name I is George and his phone number here in FL is 813 389-8848. He may be able to make one to your measurements and send it to you but the shipping would probably be high. They are quite heavy. Give him a call can't hurt to ask.
