This Mack Super-Liner, new on the road in 1991, was the pride and joy of Geoff Dibble of Dibble Indepenent Transport, Te Awamutu. Its name at the time ‘Destination Unknown’ was appropriate and summed up its travels as a bulk tipper around the North Island. Throughout its life, bulk tipping has been a mainstay, and it also travelled the South Island for some time with a couple of other owners.

Now named ‘Big Chief Sitting Dog’, this legendary V8 is currently owned by JW & L Crooks in Tuakau. Jimmy Crooks is behind the wheel these days, carting chicken manure around the Pukekohe/ Tuakau area.

With a V8 E9 engine under the hood pumping 500hp, an 18-speed Mack gearbox and 44,000lb diffs riding on Mack camel-back spring suspension, a day’s work is a breeze, as long as said breeze is not blowing from the rear forward!

The days of long hours for this Mack are getting less. Jimmy’s son, Paul, reckons she’s semi-retired now. “She’s just a glorified work ute, really, jumping on front line duties when required.”

At 31 years old, this big chief has travelled more than 1.18 million miles (1,900,000km), and long may she continue to be seen on the highways.
