Last time we were in Baja the temperature reached 107 degrees so we though it might be a good idea to get a second Fantastic Fan. We had read on another overlander’s blog that the Four Wheel Camper's were prewired for this. We contacted Four Wheel and they confirmed it. They've been an awesome resource; always answering any questions promptly and politely. After the fan arrived we cut hole in the roof and found the mount and wires right were they should be. Installing the fan was crazy easy. Works like a champ! 

First cut to camper. Scary stuff.
