If Todd Z is correct, and from what I've seen he seems to be most of the time, then I would agree that there are more 4x2's sold. I bet a very large percentage of the ones sold in the above listed states are 4x2's as 4x4's are not needed by most. I had a 4x2 truck once and never again atleast not unless I move. In Canada I would think there would be more 4x4's. How about those numbers Todd??
Oh and MB I see where you are from, you ever go to the drive-in in Bridgton, I went there twice this summer in the ST we loved it.
