Your engine doesn't draw power to keep warm. I would just go have the batteries tested and if they are bad they should either be under warranty or replaced. When trying to start a truck cold it takes more amp draw and if your batteries are already messed up it could be close to impossible to start your truck. There are also truckle chargers that a couple poeple I know use on their rigs that are plugged into the winterization that continually charges their batteries when plugged in to allow them to stay good and strong.
