If you're concerned about hard glass panels lifting your roof off at speed, why not look into flex panels? They are usually peel and stick, fit close to flush, and are only slightly lower output than hard glass panels, in most cases. Winnebago uses ZAMP panels and hardware on some of their newer stuff.
You could send a note to or@winnebago.com and ask your questions, as was suggested.
