I just thought I'd show you guys how I had put power in the bus. I had been given a battery isolator so I put that in, grounded it to the chassis, later hooked it up to the positive termials of battery 1 & 2. I then put in a heavy duty second battery, grounded it to the chassis and later run all the cables (cable-tied the cable from the isolator so it would be out of the way). I then hooked up the positive from battery 2 to an inverter, secured in the spare wheel well (and grounded to the same point as battery 2). Now I can plug in anything while camping and it's all hidden under the bed.
