Payload might have been around 13 ton but I can’t be too sure, R Steenburg & Son who I was an apprentice fitter with late Sixties had many Fords, one of the Steenburg Brothers was married to the owner of the local Ford Dealership so Fords were always included in the fleet. I remember the Trader artics well but I think they used a Taskers automatic coupling similar to the Scammell, Taskers were something to do with Ford anyway I think. The first real trips away with my Father were in his Four Wheeler Trader from the same company, reg No 507 FUP, what a flyer too, until a mate of his blew it up when Dad was on holiday, he wasn’t too chuffed. They were a hard working reliable motor for the weight range they were in, I think then almost everybody must have drove a Trader at some point. Franky.
