The Marchi eleMMent (pictured above) certainly looks like a crazy futuristic concept bus/RV, but it is real. The crazy design is based on on of the Luigi Colani truck concepts. The eleMMent sports a 500 horsepower engine, is 40-feet long, has a fireplace, a pop-up sky lounge (with fog machine), and glow in the dark paint.
The RV version has about 500 square feet of usable space, a master bedroom with a 40-inch TV, a spa-like bathroom, an integrated vehicle wash system (?), and a couch and table that transforms to a bar and lounge at the push of a button. Pictures after the break.
