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.
