How are your solar panels mounted?

I might see using tape if you've got a solid material roof, like sheet metal or fiberglass. I think that is a small percentage of RV's, but maybe I'm wrong. Anyway, if you've got any kind of rolled out roof, like EPDM, using tape will only be as secure as the bond between the rubber roof and sub-roof. Which as we all know, from seeing bubbles and even sails when that bond fails, it is not a reliable bond over the entire surface.

Also don't think your only concern is the wind created by travel. You may see high lift forces any time the wind blows, while parked, as well as side winds while under way.
