I don't know whether this is an aftermarket deal or what........but yesterday as I was watchin the stream of cars come down the overpass, headed towards the football stadium.....I spied a white Avalanche (possibly an Escalade EXT) with what looked like a Topper/Cover over the rear section.
This striked me as odd, because never had I seen any of these vehicles w/this kind of accessory (even on Chevy's website). If I would have been a little quicker w/the camera, I'd have a few shots to share.
