RFW (Robert F Whitehead) is an Australian specialist manufacturer of all wheel drive trucks.
This eight wheel drive 8x8 RFW truck chassis is towing what became a six wheel drive 6x6 trailer when a second engine and transmission were added to make a 14x14. The trailer unit is computer controlled to keep in-synch with the prime mover. The glamorous unit has a most unglamorous job, having been fitted with specialist equipment for cleaning Queensland sewers!
