The main reason I run two batteries is for the plow. It sucks a lot of juice raising/angling it several times a minute. I also am running the mini lightbar on top, headlights, two rear aux. lamps and two front/side aux. lamps (not shown in pics) in addition to the heater and stereo. So that puts quite a load on the electrical system.
