20 Amp Circuit to Support 2nd A/C Unit
I'm pretty sure one of you have already done this the easiest way, so no need for me to reinvent the wheel, right? My trailer is a 30 amp system, so I believe the easiest/cheapest method is to add ...

The pedestal should have two breakers, a 30 amp and a 20 amp.
Inside the rig, locate if installed the power cable to the location of the new to be installed AC unit. Extend it to a location that is accessible on the exterior of the rig near where the existing shore power cord enter. Install a male 20 amp cord body. You would then need to plug into a standard heavy duty #12 extension cord.
The pedestal should be wired with sufficiently sized conductors to support both the 30 and 15/20 amp GFCI receptacle. Chances of your rig maxing out the 30 is not likely.
Installation of a 50 amp system into the rig is not cost effective.
Thinking about this a little more, this arrangement would allow the a/c to run off of the 20 amp breaker at the box, and I could utilize the 50 amp breaker at the box with a 50 to 30 amp adapter and plug the existing 30 amp cord into that. So I would have 50 amps available. And I think costwise this might be the best option.
