we camp all year round,put bubble wrap on the windows acts like dual pane helps cut down on the moisture in the unit. will also run the vent fan above the stove and the bathroom vent. than have taken spray foam and filled some of the open air areas. I think the coldest that we have been out in the Zinger was 29 degrees, and one New Years eve in the Cruiser it got down to 20 degrees on the coast
