It is not economical to run one shift at a plant, KC might be in trouble of closing, save a new product, or greatly increases Fseries Volume, highly unlikely with gas and economy. With Fseries sales in the 400-500k range two plants are more than enough to build an ample supply of trucks.
Bernie isn't a company man so I am guessing he doesn't know what he is talking about, or what he said is long out dated, If DTP's C-Crew makes it through spring it is most likely going to stay on for a long time, consider how many people do the plant tours on the weekend, who wants to tour a plant when its not running?
Sorry to paint a bad picture for all those employees at KC but reality isn't always pleasant, nor should it be ignored.
