A little more info was requested: I stake a guy line out from the legs at about 45 degrees. The legs are vertical. The top of my guy line has an "S" hook that I catch into the knuckle at the top of the leg then I lead the guy line out at about 45 degrees to the side (as mentioned). Then I snug the line up. I don't stake the bottom of the legs. The stakes I use are Coleman stakes that are pretty hefty and have a platic doodad at the end that serves to keep the rope attached to the stake.
I have some REI extendable poles I wedge into the outer rail and inside the case and have a pair of awing de-flappers to stabilize the awning fabric.
In an "emergency takedown" I just loosen the guy lines enough to unhook the lines at the top of the leg and drop the lines down on the ground. Then, after removing the center rafter I start cranking the awning in. I never anchor the awning to the trailer side.
If I have awning lights up, I've been known to just leave the lights in the track and the legs hanging and crank the awning in enough until the legs are hanging against the side of the trailer. That means the awning is not quite closed all the way but not exposed enough for a problem.
After the emergency, just crank it back out and all the lines and stakes are in the right spot to reattach the guy lines and snug them up.
That day my awning was all the way out, but no lights attached. One stake was in the grass the other was into the gravel of the site. The guy line with stakes was still attached to the detached awning. I thought the stakes were well seated.
The group consensus was to tie the outer edge of the awning to the picnic table relocated to the outer rail area. The theory being if the picnic table blows away I've got other things to worry about! No other awnings were lost this trip. Sometimes it seems my purpose in life is to show others what not to do.
I was intrigued by a Fiamma-brand plate that slips over the bottom of the leg and gets staked into the ground. This allows the bottom of the leg to slip out of the plate quickly for those emergency take downs. Resists upward motion, but can slide sideways out from under the plate. I bought a pair to try out on the next awning. I must have bought the last set. $22 as I recall. More stakes than a cowboy picnic! I don't mind extra time during set-up and break-down so long as the temporary break-down is relatively smooth/quick. Might be a bit before I can give a product review.
I've tried those corkscrew anchors that the legs attach to but I found they are too difficult to free the leg from in an emergency.
BTW, the Coleman stakes look like these but with a green top.
Nice video about the awing install! My 16 footer has rectangular square fiberglass pieces (~1/8 to 3/16 thick, about the size of the bracket bases, 1 per bracket) under the brackets with holes that match the brackets and are riveted to the roof.
