Well, yeah. That makes sense, I thought you meant something like, they had trucks smaller than 1-Tons with dual wheels.
While we are on the topic, could you explain some of these model numbers on this picture?

I would think what I have is the "3809" being maybe the lighter 1-Ton? And then a 3859 being a heavier 1-Ton?
