Nice pictures I guess you wouldn't have a problem with those slide toppers flapping with a foot of snow on top.I'm in agreement with John - get 'em! Too much snow to have sitting on top of the slide itself, it'd probably try to drip inside as it melted. Since they are spring-loaded, as it melted, the awning went back to it's original position. Yes, without a support of some kind, the wind make them a bit noisy at times. (I'm anxious to see John's photos, too!)
I LOVE MY CYCLONE!
here is what i have done to support my slide awnings. It's simple to do and easy to carry. Hope this helps.
