Good Job. The pedestals usually a have a 50 and 30 amp outlets.

Finally got it done. I ran an additional cord to the power pedestal, per the recommendations here. I ran power out to a 30A secondary receptacle to the exterior body of the trailer.

I now have 2 receptacles for power. My factory 50A, and a secondary 30A dedicated for the 3rd AC. If I am planning to use the 3rd AC, I simply run the secondary power cord.

Works like a charm, and looks factory.

Thanks for the advice here. I appreciate the guidance.

We did a similar thing. We had a 3rd A/C installed to keep up with the hot summers down here in Texas. It is in the middle of the 5er where a MaxxFan was located. Apparently the openings for both the fans and Dometic A/C's are standard, 14-1/2" square, I believe. The installer was able to run the power and control wiring in the ceiling by using the MaxxFan's wire to pull it. He installed the thermostat for the new A/C in the wall with the MaxxFan's control alongside the thermostat for the existing 2 factory A/C's. We did not have it tied into the existing ductwork but set it to dump. It has its own 30 amp wiring that can be tied into the 30 amp supply at the power pole with a separate cord. We set the temperature a little above the existing A/C's and it kicks in when they cannot keep up. It has worked very well.
