Yes if you have a surge or EMS device at the pedestal remove it and recheck.
I do and I will try again to remove it from the circuit to eliminate that possibility.. Thanks for all the suggestions. I tend to agree that the problem is between the power panel at the pole and the RV. I just bought a replacement (female) plug for the shore cable. I also bought a new female receptacle 30A and will replace the existing one in the box at the pole. (It is a rented spot on an acre of land and I'm the only one connected to this meter/panel/etc.) Where the camper is, is subject to some salt air and it's possible that the connections at the pole are oxidized so I will check that also and redo all connections to insure continuity.
I'm going to take everyone's advice and assume the converter is fine. Will advise. Going back there tomorrow am. thanks again
