Me neither, that was why I bought it, it is kind of rare, it has a 10 bolt axle, looking to put on a 14 bolt later, also the 4x4 is with the shifter in the floor, not with a knob, it has power windows and locks but it has vinil interior, no leather, it is an LS package I thinkI didn't realize you could get a diesel in the suvs- especially the half tons in GMT400
