We have a 2006 Puma RKSS which has a front bedroom. I am wondering if the roof vent has a 12 volt wire hidden in the ceiling. I would like to put in a either a vent with a fan, or use the wire (if there is one) to install a 36 inch ceiling fan. So, would there be a 12 volt wire in the ceiling at the bedroom roof vent? if not, how would I run one to there?
