Well you had a real life comparison compared to my "afterlife" limited experience with restored vintage trucks so the weight of argument must be with you. I never drove a 1418 with a load but then again I can't remember them flying past me like a 760 Dodge or those crazy people drifting their grey boxes around corners.
I recall my old man worked for Collier Garland ,who bought fleets of petrol 190 Inters,Ford Sputniks ,and Commer Knockers on interstate......and seems they used to crash ,burn or blow up one truck a day......maybe not that many.......but the big bangers of the early 50s were Leyland 600s,AEC Mandators,and Fodens ....all very slow trucks
Back in the 50's with this AEC you would be king of the road, not because of the 9.6 or 11 litre diesel but because it had full air brakes. It and the two others in the batch were delivered 1951 and fitted with a 28' tray and a wooden cab with a sleeper bench. They were put on Newcastle - Brisbane. After a while the 30 mph top speed that came with the 5 speed box was deemed too slow and newer models with overdrive were put on the job. For two of them it was no retirement as they were taken into the workshop, chassis shortened and converted to tippers with a steel cab. They were then working coke to Muswellbrook and return to Newcastle with foundry sand. They were on full rego until 1980 from which time they worked on the BHP site reclamation for another ten years. So two are now on club rego.
The upshot is that the big Leylands and AEC's made the track
s for the Macks to follow. The Albion in the background is of the same era and would have done the lighter end of the work. Read Ray Gillilands book The Nullabor Kid to read about the hard yards they did back in the day.

I was always impressed with Gardners that idled about 50rpms ,and used to shake the trucks to pieces ......they would almost stall ,then give a kick and speed up a bit ,then the same again.......dunno how drivers could put up with it.
