Came across a video about this earth Cruiser 4 x 4 expedition vehicle from australia today. It has some interesting design, even though I am not sure about the popup being a canvas. It might be troublesome in windy and cold location. Any ways it should give other manufactures and home builders some good design idas and if your not in building your own than you could buy one. Here are some images and video of this vehicle.
