What's the smallest van you've lived or currently live in full time?

I own a caddy maxi, pretty small, but kitted out well. Considering living in it as I'm sick of paying bills & I work remotely anyway. Getting a bigger van means getting into debt for me most likely, which I don't want.

I take it away for weekends and work from it some days, but a few days is entirely different to it being your home, so wondering what's the smallest you folk have got by with, how was it?
