If you ever start living in a van, I strongly recommend considering a wood stove. It's one of the things that brings me the most joy in our nomad home. Besides, me being a romantic soul and simply enjoying the sound of fire, I also love the fact that it expands our sovereignty and freedom. With wood for heating easily accessible everywhere, even if we run out of money, gas, or diesel, we'll always have the option to warm up, cook a hot soup, and calmly figure out what to do next.
