If you ever look at pictures of vehicles on the assembly line, they will all have the same color
they don't run a red, then a blue, then a brown, etc, unless they are Staging for media pix
here is what the Rams look like after rolling off the assembly
they are lined up by the particular area that they are going to
the company that hauls them away, just has to park & load the vehicles on his or her list, they are in a line, so they don't have to go looking for each one
If you look closely, the vehicles are in bunches of 6 or 12
6 is the number that each auto hauler can carry
