Extra Cab U1750 Unimog

Custom Extra Cab

Brand new refurb and custom extra cab fresh off the line, December 2016. A true testament to the creativity of the UNIDAN team, this extra cab started it’s life as a single cab Mog. UNIDAN did a complete restoration on it and today it comes with all the bells and whistles.

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 or extra cab, 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 extra cab 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 the vehicle as a truck.

In the weeks prior to the Christmas holidays, the guys here at Unidan had a massive project to undertake. Just six weeks before we were heading to Fraser Island in this truck, it was still sitting in the workshop as a separate cab and chassis with a lot still to do to it. It was all hands on deck to get this truck finished just in time for our trip away. And what a trip it was! With our extra cab design, it allowed us to put even more of the kids “necessities” in the back while still being comfortable in the cab. If you are after the family comfort of a dual cab with the extra tray length that a standard single cab possesses, the UNIDAN designed and fabricated extra-cab is definitely the best Unimog option for you.
