Finally picked up my fleet ordered 2018 F150 a couple weeks ago. It's a supercab STX 5.0 4x4. Truck felt pretty lazy the first few hundred miles, but it seems like the trans really learns how you like to drive because it's come alive. Has the standard 3.31 gears and I'm only getting about 17.5 mpgs, but I've heard they improve a lot after a couple thousand miles. We'll see...
