The Australians work them hard, we just put hills in their way. It was just a single truck and trailer in the same configuration as the one in the link below, running at 42 tons gross weight (cf 44 ton maximum allowed on the road). Unfortunately I haven't got a picture of the actual truck which was a Freightliner FLB with lots of polished aluminium and about 80 marker lights (like a christmas tree at night).
