Not solar, but I've attached screws all over my Montana. I use a stud finder. Works good. No problems. Except the framing is aluminum, so that means drilling pilot holes for the screws first. I've not had any problems doing it this way.

Agree with others (above posts). Figure the best position on your roof and just "do it!". Don't over think! And yes, Keystone propitiatory stinks! It's easier to get a gold bar out of Fort Knox than getting a schematic from Keystone!
