On my previous camper I installed a Fantastic Fan in the kitchen and had to pull wires thru the overhead down to the circuit breaker panel. Took out one of the A/C outlet covers and was able to fish the wires rather easily thru the plenum down to the panel, seems that's where most of the wiring for the overhead lights were run.
