Thanks for the info. Contacted Forest River and it they were very helpful in providing information. Basically there is a screw in toward the middle of the ceiling (a little more toward the back and in the center, kind of over teh axle). You take that screw out, drill up and through the roof and that marks the center of the whole that needs to be routed.
They are sending explicit instructions via email...
Again thanks for the quick response and I will post back in week or so to let you know how I made out.
