You would have ceiling rafters ( 2X 3 I believe). No clue where you could pick up power, and would the fan hang too low and become a danger to people ? I would think it's no worth it just get a small fan you can clamp onto a cabinet door or sit somewhere. Ive only seen ceiling fans in 5th wheels in the main area where your ceilings are high.
