running a/c on inverter

[bumpersbird]

I have 6 Lifeline GPL-4DL Deep Cycle RV Battery in my coach.
The Tech's at Xantrex have stated that with the RV 3012 M inverters.
That running an A/C with their inverters and 6 batteries is well
within the capacity of this setup to run one A/C.

I would suggest that some of the newer rigs are capable of this
setup. If you had to build this setup, in a FC for example it would
not be cost effective. But in the case of the PT-42's according to
Wayne Clapp all I need is a single relay. So for me to up grade the
capabilities of my coach it's a no brainer.

I have finished the control box for the engine compartment cooling
fan controls look at new pics. It's over the top, I couldn't help
myself :}
