logistics: warming in winter
mouse.mousetrap.net
My approach to heating the van has evolved over the six years I’ve lived in it. My use case hasn’t changed: I follow mild weather and only rarely/accidentally get caught in hard freezes. Dipping slightly below freezing at night is about the limit of my tolerance.

Each winter brings a flurry (ha!) of first-timers wondering how to keep warm. Not giving advice in the above post, but explaining how I do it.
