I will second the products ABR Sidewinder sell. I have purchased a dual battery system from Derek and the optional battery monitor for inside the cab. That little monitor will tell me the volts of either battery at the flick of a switch.
Further when I had left my headlights on and flattened my starting battery the monitor has a switch to change over and start of my second battery. Great - did not have to get out, pop the bonnet, grab the jump leads and jump off the other battery.
