Yes, it can get pretty hot here in VA! Most of my camping is in the Spring and Fall, so I really don't need the AC.
Anyway, I removed the AC yesterday, but I don't see any 12V wiring. The 110 is there, of course, which comes from a plug on the outside of the roof. The wire runs in a track on the ceiling. In the 2516G, you have to plug in the AC from the outside before you crank up the roof.
I could run another track in the corner without fishing wires through the ceiling, but that would be my second option.
Thanks for the reply, btw.
