Seriously, since the motor will be running, a 400-1000 watt inverter wired to your existing house batteries would be charged by your MH going down the road.
Use as SHORT a run (at a gauge suitable for the inverter at max draw) as possible from the batteries; fuse according to the inverter wattage and run an extension cord to where you want to use the power.
For a 400 watt inverter, the max current at full load is 34 amps. For a run from the batteries to the inverter less than 6 feet you can use 8 gauge wire and fuse at 30 amps. At 10 feet you will need 6 gauge wire, etc.
For a 1000 watt inverter, the max current is 84 amps. For a run from the batteries to the inverter of 6 feet or less, you will need 4 gauge wire (typical battery cable) and fuse at 80 amps. Much beyond 10 feet you will need all wires including the batteries to be upgraded to 2 Gauge.
Did that help?
