Being a full-timer, and also single woman who is still employed, I don't put up my awning except on weekends. I don't want to come home and find that high winds have ripped the awning off and damaged the trailer.
I like the look, the function and space of these awning enclosures offer, however in my case I would only consider getting a freestanding screen room with the optional canvas sides because the potential for damage would be less, as would the replacement cost for the screen room. These are nifty - and at $1300 - congratulations on getting one as a freebie with your new Airstream. If you go to rallies a lot, you can ask any of your fellow campers to handle it in a storm, but if you're alone check the weather before you leave the trailer unattended.
(At an Aluminapalooza I headed back to my trailer to take the awning down because a storm was moving in. A couple dozen people were running from trailer to trailer taking down awnings - sure enough every awning down within 3 or 4 minutes. I didn't even get a chance to help. I've seen the same thing at my home campground. Campers are nice people!)
Today is a gift, that's why they call it the present.
