Wow, Dennis, I did not know they didn't produce any exended box duallies. Pretty rare as i think we all remeber that brown one on ebay months ago. Probably still there.

4X4 duallie is pretty rare too. Must be DSO spec. Wouldnm't be complex to put a 4x4 on a dually. Lots of 4x4 one ton trucks with singe rear wheels.
