Battery Bank in a PT

[trvlngnrs]

Currently I have six 6 volt batteries in a "pool" that start the coach
and powers the house. There is one additional 12 volt deep cycle that
starts the genset, but I believe it is also in the "pool" because I
recently had it out, and could power the genset slide and start the
genset.

I am going to be getting new batteries and was wondering the best
configuration is:

1) Six T105 6 volt batteries in a pool, as is.

2) Four T105's for the house and 2 T105's for the engine, with an
isolator seperating them.

3) Four T105's for the house, and 2 deep cycle 12 volt batteries for
the engine. This will be approx $250 more because a space would need
to be fabricated to hold the larger 12 volt batteries.


I am leaning towards #1 because it is cheaper ($550 with all new
cables & terminals). I would need to know that an isolator exists
beween the genset battery and the remaining "pool". That way if I
killed the 6 batteries, I could still start the genset and recharge
them with the 2 newly installed Progressive Dynamic 60 amp convertors.

The engine is an 8V92, so I am sure it sucks amps when cold. Would 6
T105's handle it?

Thanks,
