as far as the rear window being an easy place to break in to the truck that is true for mose but on the 3rd gen trucks the slider is made different and i think it would be almost imposible to break into with out breaking the glass on the 3rd gen olny one peice of glass slides and there is an overlap of glass on either side of the slider unlike all the old ones that just butted togther and you could just slip something thin in and pop the window open
