Almost certain this is correct. My 2005 Hawk came with wires just like this, in that spot, that terminate in a weather-proof outlet (black, oval, rubber) on the front/left side of the roof. And I used them for the solar-roof installation that I did last October.
That would be good news if its solar panel wires, but I thought you had to pay an extra $50 for this option? ...or is the $50 just for the plug to be installed in the outside of the camper?
I believe Steve/Stan may be at a show in SoCal this week.
