I love my new Yukon but I am rather amazed at how the rear window and tailgate area attract dust like a magnet. It's really hard to keep the rear clean. A couple of swipes with an automotive dust mop and its clean, but just a drive around the block and it's filthy again, but only the rear. I suspect it has to do with static charge and aerodynamics. The rear is shielded from the air flow so the dust doesn't blow off. Just a curious observation.
