I chose to position the 12V battery in the ICC under the camper to free up the designated space in the galley. Routing the wiring to keep it concealed was the challenge, so here are a few pointers for anyone thinking of doing the same…
The wires, bus bars and fuses are hidden behind the galley module (as described in a previous post). The 12v supply wires enter the floor of the galley shelf from the footwell of the camper…
…and then the wires were secured to the floor of the ICC enroute to the battery. (The additional hole in the floor shown in this shot is to route power to the opposite side of the ICC for lighting).
