Slide cover flapping in wind Solution
I have a similar problem on my Mobile Suites 36RSSB3. The slide cover for the rear-most driver's side slide flaps enough to be an annoyance if the wind is blowing in just the right direction and strongly. It flaps enough that I suspect it could be damaged if nothing is done to stop the flapping.
I found a strap (about 3" wide) that the manufacturer apparently intended to be used to stop awning flapping and/or hold an awning down in windy conditions. I've run the strap over the slide-out slide cover and staked it to the ground fore and aft of the slide. I tighten it just enough to hold down the slide cover. I have found that this solution keeps the cover from flapping and does not damage the slide out cover.
I could take a picture and post it, but I don't know how to post pictures. My camera takes pictures in .jpg format.
