Most battery problems are due to low water level problems. Trailers with two batteries also have chargers when hooked to 120 volt AC. When your rig is at home hooked to 120 volts for long time it is charging the batteries. I know there 12 volt loads on the all the time (detectors, refer curcuits, tv antenna amps) that draw from the batteries. If the not hooked to power batteries will be drained down. Keep an eye on the water levels in all of the cells every three mounths. It will help the extend the life of deep cycle batteries.
