Me thinks he is wondering if the 50 amp and 30 amp pedestals are separate circuits I.E. total of 80 amps. He wants his beer cooler on the 50 to 30 to20 and his rv on the 30 or vice versa so he doesn't pull amps from his trailer with his beer cooler. If they are separate circuits then it would be possible to run 50 amps/ 20 for the cooler and 30 for the Rv.
I'm just spectulating that the 50 and 30 pedestal are separate circuits. Most likely they are both on the 50 amp service.
