The short name for these Trucks in Deutschland is Rundhauber or Kurzhauber

Truck was originally used by the Bundespost as Fernmeldenotdienst (Telecommunications emergency service) but has now got a different Truck-body (Koffer) on it from the Bundesgrenzschutz (German border police) which was once used for listening to Radio signals across the border.

 The Radio Frequencies were still in the Koffer

This is a model of what my Truck would have originally looked like as a Bundespost Fernmeldenotdienst Truck.
I based my New Koffer on this as I found     the curved roof really suited my Truck.

Front Tyres:  Michelin XZL 11.00R20
Radial tyre
New in Jan 2018

Rear Tyres:  Michelin XZL 11.00R20
Radial Tyre
New in March 2023

   OM 352 with newly fitted LS5 Servo Steering

My old Front Tyres
11.00-20 Mitas NB 59
With Snow chains laid out for fitting

  This was a Diagonal style of Tyre that had a      habit of going square when I parked, then         rattled the Truck for the first 10 km until       they were warm and became round again!

My old Rear Tyres
Mitas NT 9 MIL 11.00-20
Diagonal Tyre
New in July 2010
Removed March 2023


After many days of snow fall in February 2010, I used the Truck to move some old vehicles to another storage area in the Bar 25 where I lived. The snow was about 40cm deep in places. I had to use the snow-chains as the first area was compacted snow that had become quite icy! In four wheel drive I was sliding and having trouble getting the tyres to gain traction while I was winching and towing the vehicles out!

Here is the Data Card for the Truck

Inside the Truck 2010

This is how my Truck used to look like inside in mid 2010. I built it to be functional as it all got pulled out when I did my rebuild in the winter 2010. So I tried to keep most of the building below the windows so I didn't need to remove every thing when I cut the roof off. In the end I totally stripped the inside to bare steel!

Looking towards the rear

Here is the first view I had of my Truck when my friend Boris found it for sale on the internet. So after ringing the owner, I went to look at it in December 2006 and spent a few hours going over it and taking many photos. After talking to another friend of mine who also owns a Rundhauber, I returned a week later and bought it for nearly 8000€.

     rear just after I bought it.

    Truck had only 15089 km on the Taco!

    Inside the driving cab is painted still with       Bundespost Grey (RAL 7010).

     The original Bundespost number:
    BP- 80096 painted on the dash trim.

The OM 352 motor


 Here Im trying out the Truck along forestry roads on the way back to Berlin after buying it. This was where I found out that it has a 18 meter turning circle which can make for some interesting driving situations with tight corners!  I also managed to find some muddy tracks and holes to try out the four wheel drive and the rear differential lock, as well as trying out the winch with the cable tied round a tree.

The guy I bought it from, had just about a week before I bought it slapped white paint nearly all over it with paint dribbles and runs everywhere including on the windows! It was so fresh that I kept getting paint on me. Had to wait for it to dry off properly before I could sand it back and repaint with RAL 6005 British Racing Green.

These are the ramp angles for the Truck with the new Koffer.

While working at Garbicz Festival, 2013, I had to tow out a fully loaded 7.5t Truck that had dug its self down onto its axles.
