I have to agree about new trucks being built way too high. All trucks and cars are tools to carry a load or perform a job and that is it. Make the tool if it a truck user friendly by allowing it to be loaded easier.
No need at all to have a tall full size pickup, you are not going to take it off road on serious jeep trails (too long of a wheelbase and way too long of a wheelbase), and other than to psychologically make up for a lacking of a certain part of a male's autonomy on certain people, I can't see any logical reason for a tall full size pickup that is actually used as a "tool" to get a job done.
