Back Seat Removal

What is your question?

I don't like the fact that the rear seat back rest in the Crew Cab model does not fold down, instead the seat bottom folds up. I figure this is due to the fact that they have incorporated head rests into the backrest? Years ago on my 1990 FORD super cab the seat bottom folded up and over and the back rest folded down to create this outstanding flat surface area to be used for anything, storage , sleeping. So many years later I buy a new truck and none of the Mfgs make rear seats like this. I haven't been able to find repair manuals on my truck as yet, maybe still too new? I have searched the internet, no luck. How can you remove the fixed back rest without going through trial and error. Anyone? thanks
