We recently had a Mitsubishi Training weekend at De Kraal, which is near East London in South Africa.
Of the 13 vehicles, my 1989 Gen1 (with Di-D transplant) was the only 4x4 with two open diffs.
I made all the obstacles bar one.
(Quite a few of the newer vehicles did not make some of the obstacles I did!)
Some pics taken on the day.
