In 1971 Vehicles Constructors Division (V-con) of Peerless Manufacturing of Dallas, Tx put a truck into service for testing. It was set up in the Pima Copper Mine, south of Tucson, Az.
For 1971 it was a pretty radical departure in truck design. The entire truck was built under the dump bed, with eight tires pretty evenly distributed under the truck. A 3000HP Alco locomotive engine/generator was hung transverse between the axles. The operators cabin hung low in front. It looked like something out of a science fiction movie.
In an open pit copper mine, in the pit, the traffic goes to left side, like in England. It puts the ore truck drivers on the edge of the road and more able to judge their distance from the edge. The down side is people, including people who work there, tend to forget.
One of the people who forgot was a shift foreman. He went flying up the hill in his usual hurry, on the wrong side of the road. He flew around a curve, right into the front of the V-con, under it, and out the back. It rolled that pick-up up like a prince albert cigarette. While trying to find the driver of the pick-up they heard noise in the bed. They used two front end loaders to pull the bed open and there was the driver, lying lengthwise in the bed, with hardly a scratch on him.
The big truck just rode off into the sunset. The rights to the truck were bought by Marion and they never sold a truck.
