Line drawing of the EcoRoamer when it was just an idea
At the center of our adventure is the incredible EcoRoamer. We call it: “The world’s first carbon-neutral, 4wd, family friendly, expedition vehicle”. We spent two-and-a-half years building it in 2007/2008, with the amazing help of Jeff Kuhl and his family in Sturgis, Michigan. Jay designed the truck from the ground up to run on solar power and bio-diesel, using a Ford F-650 as the base, but then cutting and stretching and adding all over it with entirely recycled and sustainable materials. If you are interested in the build, and have many, many hours to kill, there is a full write-up with diagrams, spreadsheets, photos and arguments over on Expedition Portal here:
