It seems to be a mix between the "normal" 300CDI and the 300CDI 3430mm heavy duty 4300 kg truck.
I picked it up watching the video where the truck is crossing the river. It seems to have the standard rear brake drums and studs, most likely not the extra heavy 2800kg rear axle.
The specs I found in the internet show the standard track width, not 1550 as on the heavy duty axles.
Would be nice to get it and the Professional station wagon into the SA market.
Would be keen to find out if they have sorted the air cleaner, the old Professional system is a desaster
The air cleaner is too small and clogs up very quickly, then starts carrying over dust. When driving in dusty conditions one has to monitor it constantly. I have not had one air cleaner element lasting a full service interval. The snorkel is essential to take the air from higher up where there is less dust. A pre-cleaner with a cyclone effect would most likely assist.
The noise is an issue on its own, it sounds really powerful, especially when charging a dune at full throttle, I like the baking when you take the foot off that loud pedal.
A bit annoying when driving with open window.
The specs are not comprehensive, but it comes out clearly that the cab/chassis is full bore heavy duty G. The 2800kg rear and 2200kg front axles are mentioned.
The higher "slope climb ability" indicates lower diff ratios.
Sorry for wasting your time with my wrong observation above.
