I know that the differences between FX4 and Lariat with 4x4 have been discussed but I have some specific questions I was hoping some experienced off roaders could answer. As far as I can tell, the two real performance features that make the FX4 stand out are the locking rear differential and the stiffer springs (I'm already getting the max trailer tow package so I'll have the same gearing regardless). How beneficial/necessary are these two features. I live in the PNW so I definitely see driving in mud a lot but I'll probably never go rock crawling.
Thanks for your help
