Incidently, the creation of the dually pickup was essentially a "joke", or a "lark".

We used to employ "chase trucks" when we would take Engineering road trips out west. These trucks would follow the test vehicles being evaluated, bringing tools or supplies along the way.

Back in the early 70's, as sort of a joke, some of the development engineers stuck a dual rear wheel axle under a pickup and installed a camper, creating a mobile break room. During the course of the trip they noticed it handled so well in the mountains and on curvy roads that eventually, as more upper managers had an opportunity to drive it, the "Dooley" was approved as a factory model.

FWIW -
