I didn't know those drill-free brackets existed. Like you, I'm still peeking in the windows of solar. This moves me up a few rungs. The attachment system is the only thing holding me back. I would glue them and then lay Eternabond along the otter edges. No drilling here...just can't bring myself to do it. These coaches are already pre-wired for it on the roof, right? Seems I read something about it in the papers that came with the Owner's Packet.
