About the only rule of awning use I go with is to not tie them down...
If it's too windy that you need to tie it down, it's too windy to have it out in the first place.
It'll just take you that much longer to bring it in if you need to quickly.
I've had my manual awning out and been out in the middle of the night in my under ware bringing it in before.. Funny for sure, but was able to do it quickly.
Now I have the electric awning and it's just a push of the button if needed to bring it in in the middle of the night..
I'll watch the weather forecasts and judge from there what I do with the awning.
I've left it out all weekend at times and sometimes it never comes out..
Just depends on the location and the forecast..
Have never lost an awning in 20 some odd years of this RV thing. :)
Do whatever works best for you and go from there..
Good luck, Mitch
