I have side dinette and battery box is full so I hung it on exterior wall of Battery box ...an ideal spot. When one sits down it is behind your knees so no contact.... wires are short (12") into Battery box. But the real plus is cooling... it is perpendicular, next to the access drop open door for turnbuckle. So when driving I leave that open. it is inches away and has lots of air flow.
Great idea!
