I had a second AC added to our Gemini. The one it came with in back was working fine, but in hot weather with the sun beating down on it, there was no way it could keep up with that greenhouse heat generated in the cab area, plus the rest of the RV. The second AC solves that problem quite nicely. I had it done by the dealer, about all I can tell you is all the wiring is out of sight. I had a second digital thermostat mounted in the front living area that controls the front AC. Power to it is via a second 30 amp plug, mounted next to the existing one, I use a Y connector from both 30 amp outlets to a single 50 amp cable, plugged into the parks 50 amp service. It all works seamlessly.
