We've been living in our 2010 Sydney 32.5 Fifth Wheel since May in the Pacific Northwest. Cold snap last night - down in the teens and today no water. We had disconnected the hose and filled the tank anticipating the freeze and kept the furnace running all night around 60. We thought we had a 4 season rig here?! SO frustrated. Decal on the door proudly states "Arctic Barrier" and we were told the underbelly was insulated and ready winter. Been running the furnace all day at 75 (sweat sweat sweat) plus extra heat in the "basement" = no water. Ideas? Expected temp tonight 14.
