This is the video I helped to film in Oman in 2015 with Oberaigner. As a result of driving the 4.5 tonne, 6×6 Sprinter for four days on tarmac, gatch track, rocky trails and the Wahiba sands desert, I was suitably impressed with its performance  and ordered one later that year, as the basis for my ‘Travel Truck’.

As you’ll see in the video, the Oberaigner 6×6 also has an impressive wading depth (600mm) and has the benefit of five differential locks and a low range transfer box for all terrain capability. I’m having mine fitted with a PTG tyre inflation system, which can fully inflate all 6 tyres to an operator specified value in less than three minutes – about 15 minutes quicker than using a garage compressor, or a small capacity unit like a BushRanger. Tyres on mine, and as fitted to the vehicles in the video, are BF Goodrich A/T 285/75/R16s. Ground clearance fully loaded is 257mm.

We also had with us a 4×4 Sprinter fitted out as a troop carrier. We used this as our ‘main store’ for all our provisions, luggage and recovery equipment. Although you can’t see it, the 6×6 body was filled with enormous truck tyres and some spares for the Sprinters. This was done to bring the vehicles weight up to around 4.5 tonnes, so as to create realistic test conditions. Watch the video carefully and you’ll see the 6×6’s front and rear axle articulation, which is really quite impressive and helped it to perform so well in the sand. At one point you’ll see it climb up a 1:1 dune slope with ease – not bad for a ‘delivery van’ !
