Our Class C had a Carefree by Colorado electric awning. Ours did not have a wind sensor. When we started camping seasonally, we decided to tie it down. The
system we owned had large, heavy duty springs that allowed the awning to move gently and evenly when it was windy.
Our seasonal site was directly across from a farm. The entry door faced due west and we would get winds that would just come out of nowhere, all hours of the day. If we expected a storm, we brought the awning in, but there were plenty of times that we'd go down to the lake or the pool or run to the grocery store with no bad weather forecast and then out of no where, our site would get windy, but still no storm. After a while, bringing everything in every time we left the site got very old, especially since we were there for 5 months.
Our awning went through many storms, some pretty strong that came out of nowhere in the middle of the day or night. When we sold the Motorhome, the awning worked just fine.
