    It seems to be recommended that you do not split the house bank as you
    suggest, so I suggest you keep to a single house bank, even if the
    batteries involved have to be some distance apart. This will minimize
    the depth of discharge of any battery, and it is the deep discharges
    that are harmful.

    If the batteries in a bank are widely separated, you should try to
    arrange cabling so that you have equal length cables from the common
    ground and positive points to each battery, to ensure that the two (or
    more) sections of the house system will be charged and discharged
    equally.

    As another poster suggested, it is probably not advisable to put
    batteries in the accomodation space - you will get acid fumes from the
    batteries. It may be acceptable to do this, if you can enclose the
    battery compartment, and vent it outdoors.
