Unimog U1700/38 DOKA


This well known and much loved Unidan Mog is back up for sale. A true testament to the creativity of the Unidan team, this dual cab (DOKA in Unimog terms) started life as a single cab Mog. Dan did a complete restoration on it and today it comes with all the bells and whistles (plus much, much more since the current owner got a hold of it). The current owner is looking for an upgrade to a new Unimog and will be completing this work through Unidan Engineering.

Here at Unidan Engineering we have developed an innovative system that enables us to convert a single cab into a 5, 6 or 7 seat DOKA, while simultaneously increasing the physical strength of the cab. The roof has been raised to allow for greater headroom, overhead consoles and more storage, and integrating the air conditioning system into this space eliminates the need for a roof top unit. This DOKA is now a very comfortable family tourer.  The cab has been modified ready for the addition of an expedition/motorhome body, with a legal crawl-through built into the rear wall (mandatory to register a motorhome in most states). The crawl-through opening is sealed and can remain that way if you want to use the vehicle as a truck.

Since the current owner purchased this vehicle, Unidan Engineering has added a number of thing including, King Racing Shocks (for a more comfortable ride both on road and off road), front and rear winches (for any sticky situations), front bull bar (as shown in the attached images) and a rear winch bar.
