Old Duck - Yeah ... that would be really nice but I don't have any roof vents in the back of the RV.
I called the factory and, after telling me that the factory "doesn't recommend modifying the RV" (he was just covering his um ... back side) he suggested that I remove the ceiling panel to gain access to the area. Sounds like a PITA but I'll see what's involved and if it's too much then I'll go with the stud finder, cram my voltage tester up in the ceiling to see if there are any wires up there and hope for the best.
