German design student Christian Susana is shopping around his concept for a dockable and detachable RV concept which makes the family Winnebago look like a leftover from the stone age.

Certainly, this is not the first time the idea of combining towing vehicle with trailer has come around, but this one does offer some pretty snazzy design. Old Susana's concept is dubbed the Colim (Colors of Life in Motion) and its central trick is obviously the little car up front, which does the towing and can pull away for scooting around your destination.

The back half is a cleanly designed, modern interpretation of RV living; it sleeps four, has a kitchenette, and a bathroom, along with fancy storage and seating. By having a detachable car instead of towing one behind, the concept would be considerably more fuel efficient and take up less space at the campsite. At the end of the day though, it's just really neat looking. We're wondering if there are provisions to load up some filthy dirt bikes and tow a blown up CJ-5. [Tuvie, LikeCool]
