Does anything about my truck look off?

First time super duty owner. I bought this truck from a dealer but it was previously a fleet truck for a city DOT. There’s something off about it but I can’t tell what it is. Not sure if the tires are small, if there’s a body lift, or if the frame sticks out lower than other super duties. Idk what stock wheels are or if the FX4 or extended cab has a lower frame. I also am wondering if the fleet trucks are built a little differently.
