@Frances - it is a De'Longhi Pinguino 12,500 BTU 4-in-1 All Season Portable Air Conditioner, Heater, Dehumidifier, Fan - we purchased it at Costco for $349 on one of their promotions, and it is now about $399. The nice thing is that we can use it for electric heat in the cold season (and don't want to use the propane furnace) and dehumidify the rig when necessary.
@Larry - yours is an excellent solution! My current method is just to wrap the receptacle/plug with electrical tape when the weather looks sketchy - definitely not a proper method.
@myredracer - we're traveling mostly just the main big rig parks which have plenty of 50A available. I'm still not that good at wrestling my rig into the smaller sites at some areas so we have opted to go with the bigger parks/resorts - I just know I'd mess up my rig in a tight situation. Thanks for the info on low voltage - I'll definitely take that into consideration as we travel.
