I take two dog leash lawn screws which are about a foot long, put them in the ground right under the end of the awning, then take two load binder straps with the adjustable winder, loop them over the awning frame and put the ground hook into a 6 inch spring which attaches to the ground screw. When the wind blows, the springs give it a little tension and release so it is not all on the framing. Works great and never had a problem. Now if it is that windy that the awning is bouncing around, then I roll the awning up. The other thing to watch is to make sure you tilt the awning to the low side of the campsite so if it were to rain, the water will run off the awning, alot of work to try to dump 50 - 100 pounds of collected water off of a "Balloned" awning.
