Call Thor tech support with your vin # and they may send you a drawing showing roof stringer location. For 3 panels if they are 100 watt go with 10 AWG wire between the panels and the charge controller.
You might want to consider tilt systems or make your own if you camp during the winter months.

[QUOTE=Bama57;84722]My 2017 29h says "pre wired for Solar"...but with the limited and non revelant doocumentations that came with this new purchase, I have no idea of what that entails..[/
I called Thor's Customer Service and gave them my VIN. They sent me PDF's of the electrical for the coach and added chassis wiring. They also sent me the roof details.
I found out that their were two recalls on the coach as well.
