Awning mounts.

I recently had an episode that tore the awning from its mounting point and deposited it on top of the TM. After I retrieved the awning I saw no descernable damage to the awning. However the original screws that secured the awning to the TM Frame were pulled out. (I was surprised at how few attaching screws there were.)

As a temporary fix, I put longer screws into the original locations. I really think that I should put several more attaching screws in that assembly, but I don't know what maaterial I would be screwing into. Can anyone advise if there is a sturdy material, wood, or metal, not just foam, in the TM frame at those attach points?

A very quick, gust of wind removed the awning, no storm or sustained winds at the time. Luckily the awning still works well.

You input is greatly appreciated. Thanks
