Moby1 C2 Trailer
Taking its design cues from the iconic Airstream aluminium travel trailers, this mini-me of caravans is the ideal mobile home de choix. Weighing in at only 130kg it can be hauled by any small car or even a motorcycle. It's amazingly compact at 120cm x 200cm; the inside can be decked out with cabinets, as well as doubling as a small work space and (obviously) somewhere to put your head down.
Available for a mere $6500. But think of the freedom you'll have. Moby1 Trailers.
