mcfarmall - glad to hear someone else is using those small 3-inch earth augers. I added an eyelet with large washers in the four corners of my OFF-ROAD POPUP just below the roof line and I run 1/2-inch ratchet web straps to to the ground. My big problem was with side to side sway of the POPUP when put up.
The earth augar is also another point to tie down the awning to as well.
They go in easy and leave no marks when removed. Adds alot of safety from sudden wind storms that come up.
Using the ratchet type web straps allows me to remove the straps in quick order if need be...
