 Joe,
 You really have no choice but to mount the batteries aft.  You need them
 there for the weight and balance.  You need to put as much stuff behind
 the batteries as possible.  IE starter contactors, elt antennas, etc.
 You will still be nose heavy.  I land with full aft elevator input with
 the same configuration as you but with no A/C.  I have the large
 Mountain High o2 system with the bottle under the baggage compartment
 floor.  I also keep a a tool kit, aircraft cover, extra oil, and any
 baggage as far aft in the baggage compartment as possible.
