According to an official book titled "Les camions Volvo : 60 ans d'histoire",

- the White Road Xpeditor 2 was launched in 1976. It had a new cab, not a modified cab from the previous Road Xpeditor. Because that one was itself derived from the old White 1500 series truck.

- the Volvo-White Truck Corporation was launched on August 31, 1981. The White range was revised, got a Volvo diagonal bar, and relaunched in June 1983, including the Xpeditor.

- That lower cab version is actually pictured in the book. It's from 1986 and was called Xpeditor Low Entry.



- The difference between the WX-42 and the WX-64 models ? I suppose it's the same as with every other american truck, and refers to the number of axles. 42 means a 4x2 truck, 64 a 6x4.
