Steyr 12M18

The chassis of the expedition truck is a STEYR 12M18. It was originally build for the  Austrian military (M in 12M18 = Military version; Year of make = 1986*) and overhauled and remodeled over the last 3 years (2015-2018). It’s now registered in Germany as a Motorhome/RV*. 

One of the most remarkable things about this truck is that it has a turning circle similar to the Land Rover Defender 110, but with far more comfort (e.g., air-suspended seats)

* It is possible to import this truck into the USA  (25 Year rule). It can also be registered in many other countries under the cheaper  “oldtimer” class (including cheaper taxes etc.)

Living Unit

An FM2 Zeppelin-shelter from the German military forms the frame of the camper unit – the living quarters. Combining the STEYR 12M18 with this durable and sturdy container resulted in an expedition truck that can handle all kind of roads and climates. 

We paid extra attention to the quality of material used. It had to pass the test of time and of offroading. Therefore, we often couldn’t use the standard material available for Motorhomes/RV’s. Instead we had to resource highly specialized and custom-made materials.
