The travel restrictions and the fear of not being able to get the boat off the water if necessary was too great. For the first time in 20 years it looked like I would spend the summer in the house. I started to feel like I would need fresh air to survive. In July we put a tent on the screened porch to avoid drenching thunderstorms and began sleeping outside seven nights a week. As fall came the evenings still felt good but by the end of October it started getting pretty chilly. I lasted in the tent until the end of November. My friend stayed out there another three weeks. It sounds weird but we found taking a hot shower before going out to the tent made getting to sleep easy. At 32* I began to feel it. It was so nice to hear the owls and coyotes that I hated to come inside but I drew the line at head under the sleeping bag and my nose feeling frozen!
I wish the best for you and your experiment. I understand where you are coming from. Be careful with the karosene heater inside. Carbon monoxide. Take care! My best to you.
