Not sure, I don't think using your registeration for another car would be a problem, and you still are driving a Mopar. I'd stick that sticker on the windshield ( if your not aware, they do have a specific area to place it usually upper corner of drivers side), no sence paying to park ourside the show grounds. And as far as I'm concerned, parking around the tent is fine with me, your Chally would have a place anyway, right? Now if there is any hassels with security, we'll just call Don home and let him take care of it.
