With a tear that small I’d just use one of the tape kits mentioned above. But if it gets worse, Camping World replaced mine for under $250, which I didnt think was too bad (if you didnt want to do it yourself).
Update – we ordered the Camco tape from Amazon, came yesterday and applied it without a problem. Seems to be sticking extremely well. We rolled up and unrolled the awning several times, no issues. We’ll see how it holds up this season. Thanks!
