Short answer is "it depends."
If you have your camper plugged in all winter and you have a newer 3 stage converter, just leave the batteries connected and charging (trickle) all winter. Just check them every month or so for water level.
If you do NOT keep your batteries plugged in all winter. Remove them and keep them some place warm. LABEL which wires are which so you don't reverse connect them in the Spring.
Batteries not on continual charge will quickly lose their charge due to parasite load and internal resistance and the electrolyte will freeze; bursting the battery case or cracking the plates. Both Bad.
