I think the problem with most rv’s is the awnings are simply mounted to the wall with no backing plates since there is no access to the space in the wall. I can’t see the wind being able to rip off good quality gutter mounts. Now the awning could be destroyed, and possibly beat the side of the van up if the legs weren’t anchored down well. That’s why we’re going with Eezi-awn. I’ve actually seen a couple of these deployed in 50 mph gusting winds at Expo a few years back. With the legs staked well, they were rock solid.
