The engine should keep both batteries charged while the engine is running. The rear battery (the house battery) may supply 120 volt power thru an inverter/converter. To see if you have an inverter/converter, plug in a 120 volt TV while you are not connected to shore power (a power post) and see if it works. If it does, you can have the TV on while driving down the road (as long as it is not in the field of view of the driver since that is illegal.) If the TV doesn't work, then you would need to have the generator working to use the TV. As donn0128 pointed out, using the inverter/converter to supply 120 volt power while the engine is not working can run down your battery very, very fast.
