WE go every other weekend here in Michigan because DW gets wired up if she is in thehouse to long in the winter... TT is stored at campground in northern Michigan, the shower/bath house is open all year and heated. No water or sewer at site, so we use porta potty and water from home. We do have electric hook up so i fire up the furnace to get the place up to temp, then 2 elec. heaters take over from there. I am currently at the campground at the inside temp is 68, outside temp is 7 We have roof vent open with fan spinning, have R3.3 foam insulation board covering 3 large windows. We have zero condensation problem...we have Cable TV and Wi fi also.. Live is tough I tell ya!!!! :B if i knew how to post picture i would :(
