I had this happen to a left side slide out cover on a MH we owned
before switching to a 5th wheel.
The wind (about 35-40 MPH) ripped the awning cover out and
in the process broke the springs that hold the cover taught.
When I had it replaced the shop installed a set of locks to control
this ballooning from happening again.
My repair was about $800 parts and labor).
