Who else is running a single battery? Better yet who is running one in colder climates? The battery was never relocated when the twin kit was put on. Went out this morning (it was 35 out) truck barely started. I had the same problem with my reg cab with a single battery. I'm running just a single stock battery (I guess 800cca?) What single battery do you run? I could move the second battery to the bed, Don't really like the frame mount. Or I could just plug it in when it gets cold...
