Dodge 15-cwt or 3-ton swb?

[David_Hayward (RIP)]

The papers I have show that the London County Council ordered 200 Dodge tippers for bomb damage clearance, although 100 were then taken over and used by the RAF for airfield building. Delivery was to be 75 per month from April 1941...any ideas which Dodges they could have been please? If they were in service with the RAF perhaps a photo exists? I am conjecting a civilian-wheeled T-110-L variant.
