The Thames Trader was replaced by the D-Series forward control trucks in 1965. Models were marketed from 5-tonnes to 12.5-tonnes, but larger versions were added on three axles or in articulated form. The D-Series were revised in 1967 and weights went up to 28 tons. In 1981 the Ford Cargo replaced the D-Series and was more of a world truck than the British D-Series had been.
