My service is mostly fords, some of them have extended cabs so you can recline a good foot. 2 of them allow you to recline flat, there is so much room behind the seats someone could comfortably lay behind the seats. Of course I never get these trucks, I am always stuck with the normal fords that allow 2 inches to recline and my knees are in the dash...not too bad on a 12hr shift. I mean who wants to be comfortable sitting in a front seat all night. I will say they have taught me how creatively i can position myself to sleep. It usually includes one or both of my legs out the window dangling over the door and the mirror. I amaze myself quite often, of course the minute i actually fall asleep we get that 3am "I've been depressed for three days because i went off my psych meds call."
