Is that a Crescendo 8356? The inverter was on option and is aft of the battery compartment, I know in my fridge compartment if you look from the outside access its like a wire tray, there's cables running up and down, also pull out the drawer under the stove and you can see wiring running and it goes behind the furnace, you may find something usable there, does the manufacturer r3comend #10 wire? Seems like overkill to me
