I just ran down to my local dealer with the thought of trading in my MY10 for an 11. 5 HO "Back Seat" edition.
Guys fuggetaboutit! Turns out the big leather bolsters are fake (not that there's anything wrong with that) but there is no discount and they always seem to be just out of reach. Further complicating matters, there was no way I could get them to lay flat... seemed like it at first but no way. After a while, there came a loud whining sound that seemed to get louder and more annoying the longer I was in the truck.
Bottom line guys, keep what you have.
