In 2015 I bought an old Mercedes bus, took all the seats out, and built a small but lovely house inside. I named it Abie, after the Israeli peace activist Abie Nathan. I had it for three years, and then I sold it and moved on to my next adventure.
If you read Hebrew, you can read more about my bus on the walla.co.il article.
You can also check my (again, Hebrew) Haiku-photo-blog at bus.yoavmoshe.com to see the buildling process, and how life in the bus looked like.
