Weight was definitely an issue,and the little 2.6 wasn't known for its power,only for its thirst,and burning valves as it aged.
In fact some preferred the smaller engine.
The bigger the vehicle,the more gear can be loaded into it.
I remember spare axles were part of the repair kit kept in each vehicle,but i can't remember one ever being used.
Here is an old pic of one.I am guessing it is early to mid '70's model.
These were fitted with three fuel tanks,and some also had a stainless water tank in the rear as well.
Some also had bars each side running from the front bar to above the windscreen,we used to call them 'scrub bars'.Very handy as the tracks in those days were overgrown.
A relatively new one was drowned up there and it was then called the 'yellow submarine'.
It was repaired by Annand and Thompson,not like todays vehicles which would have been an instant write off.
