Sooooo, three reps later I have information that the campsites have 2, 3, and 4 prong outlets. 20, 30, and 50 amps. 110 and 240V. They can give no better descriptions. The 2 prongs I’m guessing is a standard ungrounded house plug. Any thoughts on the name of the 4 prong, 50a outlet so I can get an adapter if it’s not already in my UMC?
