Do you have an aftermarket lock on your Electric Awning?

We were headed for Salt Lake City on I-15 right after Xmas, and as we were going up the Virgin River canyon, we saw a large (about 40') mh coming down the canyon and just at that moment we saw their patio awning extend out and ripped off the side of the mh. Since the road was divided, we had no means to stop and help and often wondered how that could have happened. I'm sure their awning was electric. So I'm too, interested in if there is a lock of some sort for an electric awning.
