I have one too, converted it to 1KZ-t and R151f with a split case.
Although I respect some of the critique, I'd like to know what real-world experience lies behind it.
When we brought ours home we cruised comfortably at 60mph with a truck that felt tight in the steering, good brakes etc.
They were originally designed so simple that a farmers boy could fix them with a spanner in the woods, and is a mechanically opposite to the Pinzgauer, but with at least comparable capacity.
I went for the diesel conversion to get better mpg, and because I could.
The box on the back is the only drawback; it weighs a ton, literally, 1,000 kgs, I weighed it, a big room for improvement.
With the 1KZ-t conversion, without the box, it weighs 2,100 kgs, pretty good for a 6x6 with 40" tyres (Michelin XZL 11R16)
Don't put it down, although the price is a tad high.
