Conversion - expedition camper on 6x6 truck

Utopia Odyssey - Utopia Camper II on 6x6 Bucher Mowag Duro

Project | camper | 01/01/23

This camper conversion will be done on the pretty rare 6x6 Bucher Mowag Duro from the swiss army... only 64 in private hands?

Follow the Utopia Odyssey build on Instagram: @paulgodard_utopiaodyssey

This truck is an ideal compromised truck size with unique independent suspension which allows a continuous unit from the habitat to the driving cabin, making it much more spacious.  It is only 2m wide so it will go almost where a 4x4 pickup can go!

You can stop the video anytime to look at the different scenes in details.

Base Truck – 6x6 Bucher Mowag Duro

The truck was totally unbuilt and with no running engine.  As it was a left-hand drive, it was not possible to import it in Namibia, so the truck is registered in Swaziland.
