Operators

Turntable ladder appliances on the Dennis DF chassis were sold to a number of fire brigades in the United Kingdom, including the Tyne and Wear Metropolitan Fire Brigade.[3]

The DF was also sold to fire brigades in Hong Kong, the Middle East and Kenya.[1] DF135s were also exported to New Zealand for use as pump tenders in the New Zealand Fire Service, with some being built with Mills-Tui bodywork.[4][5]
