I have a 2021 Powerboost with the max trailer package and FX4. The truck wallows when crossing unlevel surfaces, not a good thing. I had read the fronts are actually softer on the FX4 to improve articulation. I understand the truck is heavier, but the body motions are excessive and uncomfortable. My 2013 Ecoboost 4X4 doesn't do this at all.
