Best way to tie down canapy

We bought the CAMCO 42593 AWNING ANCHOR KIT W/ PULL TENSION STRAPS and use that to keep wind from taking the awning and sending itup and over the roof. In addition to that we add three deflappers on each side of our Carefree awning to keep the fabric from flapping in the breeze. They also keep the water from building up and destroying the awning due to excess water weight building up in heavy downpours.

Yes on the flappers (we have 2 large and 1 small on each side). We also use the large screw in stakes normally used for a dog cable. Then we attach ratchet straps from the awning to the screw-stakes. During the winter months in south-TX the wind mostly comes from the north/north-west, so if you can face south you will be better off. We are currently in Rockport, TX and have our awning setup this way with a sun screen also attached.
