"IF" you were going to put Solar panels on your RV's roof and you absolutely could NOT drill holes in your roof (TPO, EPDM etc) how would you attach the panels?

If I couldn't attach my panels in a manner that involved screws, I wouldn't have solar on my roof at all. Once sealant was applied below, on, and above the screws, perhaps the screws could be removed and the panels wouldn't blow off, but there ain't no way in hell I'm relying on double stick tape or sealant alone to hold my panels on. I guess I could make some sort of metal contraption, screw it to the walls, and have it go over the top of the trailer, but there's no point when I can just dip a few screws in sealant and secure them properly.

As above, I wouldn't. The only possible solution is the tape, which is fastened to the rubber membrane. Not exactly a solid enough foundation for my peace of mind.

I don't know why you can't drill holes. There must be a hundred already.

Buy flexible panels and glue them down.

Most rigs have a luggage rail on the roof and you can put angles on the rails and hold at least 3 panels, did that with my first 2 panel's.

With a rubber roof glue can't be the only attacment. Screws are necessary. With Dicor, Eternabond and maintainance, what's the problem?

Buy long skinny panels that present the least frontal area to the air stream and HD Velcro. Did that for ten thousand miles in the last three years. Renew Velcro every two years.

as above; Flexable Panels and glue designed for both materials.

Adhesives are specifically designed for certain materials and are iffy at best for others. A good match is like welding, a bad match is like doing nothing.
