Pretty much the last two things you said.I have seen trailer plugs melted trying to supply that current. Locate the 12 volt terminals via the bottom vent. With the motor running you should see at least 12.5 volts any less and the boiler cannot reach the correct heat and performance is poor. I get approx. 13.5 and it will start to freeze after a few hours travel when it's cooler.
