You're going in the wrong direction. Using a huge battery bank kept charged
by a heavy-duty alternator is still going to be inadequate for spoiled motor
cruisers who really want a house with all the comforts of home that floats
and goes from place to place.

So, forget the huge battery bank and get one of these instead. (Save your
auxiliary engines for moving the floating home from place to place.)

These tripacs are the cat's meow. They provide heat, air conditioning,
battery charging all in one compact package. You see more and more of them
on over-the-road tractor/trailers.

"The TriPac APU provides
? cab heating and air conditioning
? truck engine block heating
? truck battery charging
? 12Von-board power
? optional 120V household electrical power

"The system is powered by a diesel engine, running an automotive style 12V
alternator and belt driven air conditioning compressor. The APU HVAC system
is independent of the truck system. Cab heat is provided by a fuel-fired
heater, and engine block heat is provided by exchanging coolant between the
APU engine and the truck engine."


I hope this helps.
