I recently purchased a 2020 Landmark 360 Concord 5th wheel, love it!, however I decided to go up on the roof to check things out and found a hard wired solar panel embedded in the roof near the front cap area. I was unable to locate any material in my owners zip folder that contained a whole bunch of booklets on electronics, etc...Can someone tell me how this works or do I need to turn it on somehow....? Thanks Gary
