I have seen a few in the RV lots. My question would be max power consumption? Or how much could you get by with? Sure think you would have to be in a 50 amp RV park. Suppose in a few years RV parks will be 100 amp service if that is the trend. Many times on 50 amps I have to put my water heater on gas if both A/Cs are running and DW is using hair dryer, coffee pot, or microwave.
