How do you stay warm without a heater or way to heat up water for water bottles ?
I cannot imagine trying to deal with cold mornings without a heater of some sort. I use the previously popular Mr. Heater Buddy in my fiberglass egg.
I turn the heat down in my house to 60 at night.... I can’t imagine sleeping in 30 degrees....
That part is easy if your bed is made warm. Lots of people use freezing temp rated sleeping bags. I use more or less covers depending on the temp. I also wear an old cloth mask to keep my nose and cheeks warm while internetting on my phone in bed late at night. My nose and cheeks thank me! My husband wears buffs on his beautiful bald head to keep it warm while he sleeps.
Maybe I should wait until I get a Jackery and solar panels ? There comes a time when you feel the need to go. You shoyld go when you have the wheels and the need and the money or income you will need to set up better as you go. We spent most of 2020 boondocking all over Nevada without solar, without refrigeration, basically without electricity. Woke up to snow a couple of times, too. It wasn't awful. There was a lot of magic in the year.
I do have a down filled quilt... and lots of microfiber blankets...oh and a wool blanket ... Can you try your available covers one night at cold temps to see if it works for you?
