After graduating high school, three Japanese buddies decided to follow their dream of a year-long cross-country road trip, from the northeastern island of Hokkaido to the southwestern one of Yakushima. But before they set out, the trio built one of the coolest road trip cars ever conceived, from a decrepit mid-80s Toyota Toyoace.
The men are neither carpenters nor engineers, so the project took two years. The truck has two stories: the upper deck is a sleeping area, and the bottom has a fully-functional kitchen and bath. It even has a full-size bathtub! http://japanesenostalgiccar.com/blog/2008/12/04/japanese-road-trip-in-transforming-toyota-truck/ -via the Presurfer
I bet that thing would ebay for a LOT more than that.
