Imagine a compact, pod-shaped caravan that you can attach to the back of your car, so small that it fits into a regular parking space, but largely enough to sleep two. Now think of a unit with an innovative design tailor made with weekend getaways in mind. Got the picture? You're likely imagining David Tonkinson's Capsule Caravan, which has been designed with the young, urban iPod-loving generation in mind. One thing is clear, this concept caravan is definitely not your parents' RV.
