I went with the negatives years ago and wish I hadn't and went ahead and installed toppers. The wind issue was the killer for me even after reading several fixes for topper flapping, consisting of various spacers to hold them tight, and provide for drainage. In the end, with covid and medical, our rig got way too much Arizona sun, resulting in UV deterioration of the slide seals requiring they be replaced. If I had this decision to make again I would install toppers (and still might).
Later,
