I just put a FanTastic vent fan in our 2013 Eagle 284BHS. Even though we had the $300+ 2nd AC prep w/50 amp service option, the only wires at the vent opening were the 120v romex cable. I figured out how to route some wires for 12v positive and negative from the fuse panel to the roof vent to power the Fantastic vent. There were plenty of non-utilized fuses in the fuse panel, so I wired it to use one as a dedicated fuse for the Fantastic fan.
On our previous camper, I found that a light fixture near the roof vent location that was on it's own fuse. So I wired the Fantastic vent into that circuit. It worked quite well.
