Sounds like a 30 amp outlet would be fine, then. However, I only have a 20 amp outlet currently available, and have to use two cords to reach it. Based on Beaker's post, that might not be a great idea?
Was parked at house, sleeping in house, thought I smelled electrical fire but didn't see anything. A couple of days later, was around the back side of trailer where it was plugged into extension cord with adapter and saw a black mark up the trailer where it was plugged in. Adapter was melted.
Was washing the present trailer and got a tingle when washing the bumper. Measured voltage bumper to ground(wet concrete) and got 10 volts. Replaced adapter and voltage disappeared.
Maybe cheap adapters, maybe not, maybe the cord.
No longer is it plugged into house except when in use. I do put a battery charger on it now and then.
