my lot currently has 14 trucks (pretty low right now) and 2 are 4x2...
here ya go... just looked up my years numbers at our little dealership... it should be a pretty good idea though...
102 rams sold... 10 were 4x2... all but one of those was a reg cab.
actually surprised me that it was almost 10%... i would have guessed 5% or less. forgot we had a fleet buy 5.
