I live near Baraboo, Wisconsin.
I use my TT for deer hunting. 3 of my daughters camp with me. We do not use the water system in the TT because the TT is not built for winter camping.
Will you have power where you are staying because the furnace will drain a battery overnight if it gets seriously cold. I recharge during the day with my generator for the next night. I keep the thermostat at about 45 to help the battery last the night.
Someone mentioned condensation. It is definitely a problem with 4 people and the thermostat set low.
