Slide topper in wind.
I have a 2018 Thor Vegas with the rear bedroom slide only. In strong winds, I turn the rig into the wind to prevent sustained or gusts of wind from getting under and, possibly, damaging the topper. I carry a telescoping ladder in the clothes closet and use it to clear any debri from under the topper on top of the slideout. You should always inspect that area after a wind event and once a week or so clean it?
