modern heavyweights

[Keith Webb]

I think this was the biggest truck used after the war in 1957-58. There were 5 of them made by MACK for the purpose of serving the DEWLINE (radar) in northern Canada. They were to go West to East across the top of Canada. By time they got to Yellowknife the terrian was too rough for them and they were brought South, where I saw them in Grimshaw Alberta. The front axles were over 11 feet wide, the trailers were 90 feet long. The frames of the trailers could hold thousands of gallons of fuel for the truck's 600 hp engine. They could haul 164 tons on each truck. The trailers were left here for scrap and the tractors were hauled to Oregon to do logging as they were too heavy for the roads
