My dealer said my 2004 FX4 S-Crew w/ Blazing Yellow/Dark Shadow Grey is sub to plant, but he still cannot provide me with a VIN#. He said sub to plant means the truck will be built in the next couple of days.... Is he accurate?

 

Sub to plant means you've got a VIN. You should have build week on Monday. He should be able to give you a VIN, its on the same printout that says SUB to Plant. Build won't be for a while thought, usually about 3 weeks later.
