Before I would spend much time looking for a problem that may or may not be there, I would plug in to a 50A outlet and see what happens. I would suspect there is an automatic switch in there that is not powering the inverter due to the lack of amperage available. A 10A service is way too small to run your MH. If the batteries are in decent shape, they won't freeze at single digit temps.
