Hey Jon, there might be 12 volt power ran to the vent opening as well as the 120 volt that would allow you to install the MaxxFan Deluxe Roof Vent Fan part # MA00-06401K that you referenced but it's hard to say. What RV do you have? Is the ceiling ducted for a ducted AC unit install or is it non-ducted? Ducted would have better chance of having 12 volt power.
