TonyTiger - Thanks for the response on the overhead fan. In our unit, there are two (2) overhead ceiling lights. One near the rear and one near the front. The 14"x14" roof top opening is closer to the front set of lights. Both have switches on the fixtures, however, there is a wall switch near the entry door which must be on before the front set will work. Makes it nice when entering the unit to flip a wall switch. The factory assured me that an embedded plastic conduit runs from both sets of lights all the way to the roof top opening. To make the overhead fan run if wired to the closest overhead light, would have to flip the wall switch on, shut off the overhead light on the fixture, and turn on the fan. But, then it would be easy to shut off the fan if leaving the unit. I guess I cannot think of a very good reason why either would or would not work well. Was looking for your opinion. Thanks.
