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.
I do have a complete set of wiring plans - AC and DC.

I got stranded once with dead chassis and coach batteries
The Xantrex charger is toast and being replaced. The house batteries were showing only 9.71 volts. The engine batteries did not have enough voltage to crank the diesel engine.
I am replacing the 6 volt batteries (I have no idea how old they are and individually, each showed less than 5 volts) and replacing the Xantrex Inverter/Charger.
The battery boost emergency switch does NO good when you do not have enough voltage to start the engine or the generator.
There must be enough load on the batteries to drain marginal batteries in just a few days. The engine was cranked on Thursday and operated for about an hour and the batteries were down on Monday.
