Thanks for your reply, Lorna.
I know what you mean about wind destroying awnings. I lost an awning to a freak thunderstorm in 2004 or 2005 and I was watching the weather. I thought I had more time, but it came up so quickly. I ran outside to take it down, but it was too late. The awning ripped out of my hands and wiped out a skylight, the AC shroud, and cut up my rubber roof. Several folks in the campground also lost their awnings, the storm rolled a pop-up camper, and damaged the campground's inner tube enclosure. Luckily, I had purchased an awning rider on my insurance and the total repair was covered.
Even still, I will want an awning on whatever bus I get later. I have one on my travel trailer now (a different trailer) and we love it. High winds are not as frequent here where we typically camp in Texas, but they do happen and what I've heard over and over is: If you keep your awning out, it's not a matter of if, but when it will be damaged. So, I only keep mine out and extended only when we are there and I retract it at the slightest hint of a thunderstorm. When I feel confident that we won't have bad weather when we leave for a day trip, I will at least lower the awning to reduce the upward wind load. If I'm not confident in the weather, it gets retracted.
I also use the pop up standalone canopies when we camp in the summer, and I usually try to take them down when we leave. Come to think of it, I lost one of those to high wind as well. That was just bad luck, though.
I've looked at awning search results, but I can't find many details on the nuts and bolts of the installation, just that they are attached and look good. So, I guess unless I can find other information in the meantime, I'll cross that bridge when I get to it.
