Just finnished my first long road trip pulling my 5th wheel. Seats (leather) in my 03 were the most uncomfortable in all my trucks. My 99 power seat allows the seat base to move up and down on the seat back. This allows you to change the shape of the seat on your butt and back. The 03 seats are fixed at the hinge area and simply pivot forward or backward. I got numb butt after only 4 hours. Anybody else having this problem?
