2002 27P Bedroom Ceiling Fan

I was unable to find anything on this subject, so I am posting here. I recently purchased a 2002 Minnie Winnie 27P. I was cleaning ceiling vents and noticed there is a fan in the bathroom and living room/galley area but not in the bedroom. It appears that a fan can be installed and I was looking for existing wiring but couldn't find it. Does anyone know if the bedroom vent is prewired to accept a fan? The plastic frame has the punch outs for the switches, etc., so it seems like some models must have come with a vent fan in the bedroom. I have a pretty complete set of documentation that I have downloaded from winnebago and other sources, but can't find what I am looking for. I would be grateful for any help with this. Thank you.
