Thanks for all the responses.
I also bought a 1.3 Haier freezer, Craig's List, $50.00. Put in drivers side slide rear bay, to vent the freezer, cut a 12" x 12" hole in back of bay, pop riveted in a 14" x 14" standard metal mesh vent screen with added door screen to keep out big stuff.
Power, 110v, comes from entertainment bay on passenger side, ran 20 amp flexable cord up and over exhaust shield. Cord is spring loaded between bay and frame wire loom so it stays up when slide is put in. Also, in bay next to freezer, installed a outlet/switchbox. Outlet is GFI protected. Freezer plugs into outlet. Switch is the On and Off.
Freezer fits perfect in the bay, also is on a slider drawer for convienance if necessary.
Leaving for the GNR on Saturday, 7/11/09, will get there the 18th. Maybe will see ya all there.
Again thanks, will be using existing inverter as noted.
