[Killer Bee]

nah, it's not right back there..

I too have been driving an 02 since 02 and it's different, looking out the window at it now..

the top radius is too sharp, should be more rounded
also looks taller than cab roof, should be rounded and slope back to the rear
back window is raised or surface mounted, should be flush
that chm brake light looks wrong, bed lights are square, should be rounded
the back radius of the cab is not there, below door line, corner, anywhere
both doors appear to be fully closed and otherwise fairing evenly to the cab

those are chevy truck rear light buckets, not suburban though..

need a higher resolution picture to tell for sure but sure doesn't look like the back of that model truck to me..
