I installed this Comfort Air 14"x14" 12volt, 4amp max. ceiling fan It has a remote, automatic rain sensor, auto temp control. retail cost $395.00. I bought it for $200.00. because of the economy. I ran the wiring to the dome lighting
in the rear upper cabinet. on the interior I made a spacer 1 1/2" high. I screwed the outside of the trailer thru the 1/4 " ply ceiling material with 4 stainless screws, because the contact cement was not holding the foam lining and the ply up tight to the fg roof. I used countersunk machine screws, with nuts, a washer, and lock tight. the interior spacer is 3/4" wide and it sits proud of the screw nuts. The spacer was screwed to the plywood ceiling, and then the interior bottom trim was screwed to the spacer. It is all very tight.
