Fleetwood and most others, start the generator off the house batteries. The boost switch works both ways. The house batteries and chassis batteries, should both charge off the shore power (generator), and when the engine is running. Unless you have a COMPLEETE set of 12 volt wiring plans, I would be very shy of re-wiring a MH, as you could miss something important, that could cause a fire down the line.
