What charges the house batteries
When the engine is running are the house batteries getting charged?

The rate of charge can vary widely. Don't expect much in the way of amperage from a tow vehicle's 12 volt wires. They are mainly to keep the battery from discharging and little else. Some motorhomes have a decent alternator setup which can easily charge the batteries, others may barely throw in a charge after eight hours on the road.
