Hah, thats awesome. The only thing I'd be concerned with is getting a good seal through the bed and cab and not having to worry about the flex that happens there... I know stuff like blow through boxes for car audio have been popular for along time, but I guess this gives a new definition to the term?
I just wonder about the ineffeciencies of converting 12 V to 120V at such current to drive something that you can find with 12 volts parts in it. Wonder how much heat that inverter puts off to give juice to the A/C vs. how much harder the AC has to work to cool its own power source? o No:
