When I wire up race cars with the battery in the trunk I always add a 300A ANL fuse right off of the positive battery post then allow the wire to go into the master on/off switch and onto other fused circuits.
I did see an article in one of the mags about a relay from Painless that cuts power off of the battery using an inside mounted (small low current) switch. The relay from them is similiar to what I have on my car to cut power on the wires to the alternator and starter (I wanted to be able to work on my engine without having to worry about arcing a wrench on the starter or alternator output post). I see no reason why the relay could not be wired to a front mounted battery system to cut power to the whole car while it is parked or stored.
My reasoning for the fuse in the trunk by the battery is for safety. I would rather replace a 12-15 dollar ANL fuse than to have to see the car burn to the ground from not having it. The car could get wrecked or T boned and I prefer putting them on for safety.
