before 2004 the FX4 was just a off-road package that could be added to any f-150, they are going back to this after having it as a dedicated trim line. like we had a 2003 f-150 super crew lariat fx4 back in the day and all the fx4 added was different wheels, shocks, stickers and skid plates.
the more i see the '15 the more i like it!
