FX4 now becomes a standalone package like it was in the 03-08 years.
FX2 now is a "Sport appearance" and comes with floor shift in all lines except XL.
There's also a chrome appearance package that's available on XL, XLT, and Lariat.
XLT is the main "every man " package. There are three packages of XLT a Base 300, a mid level 301 and a 302 which is a "loaded" XLT. Leather is not available on the XLT unless it's dealer installed.
The Lariat gives you things like leather, push button start, nicer wheels and more standard equipment. Lariat also offers three lines, 500, 501 and 502. Each with more equipment than the last.
King Ranch is pretty much as a Lariat except for special leather colors and wheels and some exterior trim.
Platinum gives you even more bling and special badging and appliqus outside, special wheels, and nicer interior materials.
The limited gives you A4WD, 20 or 22s, nice leather and soft touch on everything, power running boards, the 3.5L boost, etc.
