The Whitlock Dinkum Dumper M10A, a rear tipper for construction sites, appeared in September 1962 and was the model with the highest number that has been used in the Major Pack range. Always painted in yellow with a black "Whitlock D-D 70" decal on the sides there are only 2 variations: early models have unpainted metal wheels with black tires, the later issues have red plastic wheels with black tires. The model was in production until the end of the Major Pack series in 1966.
