Thanks to everyone for the quick and valuable replies...I will continue to play it safe and conservative with the awning. This forums great and much appreciated!!!
I remember being told at a Zip Dee forum at the main awning is good up to 20mph winds and rear and road awnings are 30mph. I ALWAYS bring my awning in when leaving the campground or rally. If I'm with other ASer's that are staying at the rally site during the time I am going out, I ask if they will bring in my awning if the winds start to pickup. On numerous occasions I have closed up folks Zip Dee's and vintage awnings when the weather was acting up. When in doubt bring in the awning.
Like all the season airstreams are saying never leave the awning out when leaving the trailer or at night. It better to put the awning away at 9:00pm not at 03:00am in a wind/rain storm. Sleep tight and open awning in the morning before coffee. Been there done that, it no fun trying to close the thing with wife yelling at you for not doing it before bedtime.
If the awning is almost parallel to the ground it will tend to flap but not act as much like a sail. If the awning is much lower on one end than the other, it will act like a sail and put more load on the mounts. For best wind resistance, extend the arms just about all the way. You might fold up an arm but at least it won't rip loose from the mounts.
