the press release:

Mobility and living on the move are very important themes of our fast-moving age. People want to be mobile but at the same time, have a strong desire for a lasting home and their own personal four walls. In the camper market there is strong demand for new design and personalized, tailor-made solutions. Individualist tourists want a caravan that is made just for them.

The solution to the problem is offered by the “Mehrzeller” – the multicellular caravan. Using the online Configurator, every user sets up a design that is unique, their own layout that they can identify with.

The configuration is generated by a computer using the customer’s inputs, and then the final design is done by parameters from the architects to yield an attractive and practicable result. The caravans are produced using the principles of “mass customization”: this allows both the individual wishes of the customer to be accommodated while producing the caravan with series methods.

Screen grabs of their online configurator (sorry folks, not available in english):

The Mehrzeller thus introduces a new generation of mobile living. The project, which began as a degree project in Architecture at the Technical University of Graz, can be realized thanks to the support of many respected companies such as Design Composite, Alko, Truma, Dometic, Waeco, Alphatronics, Alugas, Jokon, Fiamma, Cleversolar, Simona, Moralt, Reimo, BMW and others.

about Victorinox:
The pioneering spirit of the company founder, Karl Elsener, as well as his love of his native Switzerland, have been the driving inspiration of Victorinox over the last 125 years. Today, that inspiration takes form in a full selection of Swiss Army Knives, professional-grade kitchen cutlery, beautiful, Swiss-made timepieces, fashionable, functional apparel, rugged travel gear and unmistakable fragrances – each embodies the spirit of the legendary Swiss Army Knife.

About Airstream:
In 1931, Wallace Merle Byam built a small camping trailer in his back yard in Los Angeles. He received so many requests from neighbors that he soon started a small company to build travel trailers that "cruised down the highway like a stream of air", and Airstream was born. The lightweight, aircraft-inspired design soon caught the imagination of a nation eager to explore the open highways and byways that beckoned.

For nearly 80 years Airstream has represented freedom and adventure, providing the perfect outlet for the wanderlust that still is central to the American spirit.
