I live in a state where trucks are allowed to squat. Meaning the front suspension is jacked up a foot or more, and the rear lowered. Most times the driver's seat is moved all the way forward and the backrest tilted forward quite a bit, and if there is a seat height adjustment, the seat is raised to its limit. It still appears to me that forward visibility is compromised. Trucks that are lifted on all 4 corners probably have a better forward view than squatted ones, but I still find that the ability to judge the distance between the truck and the vehicle in front of the truck is compromised (I've been a passenger in a lifted truck). I do not understand why there aren't regulations on lifting and squatting. As I understand it, European height sportscars are not allowed to be sold in the US with the European suspension (DOT rules?), and the cars need to sit on an additional 2 inches or so (which means business for aftermarket suspension kits).
