Zombie-Apocalypse Survival Truck Is Out Moonlighting As A Storm Chasing Vehicle

Somebody took these pictures at a gas station in Kansas. They show what is allegedly a tornado chasing vehicle (they're hot on the tail of that one that sucked Dorthy to Oz). Now I've never watched Twister, mostly because tornadoes scare the shit out of me and I was born with a monster vajhyena (its bark is worse than its bite), but I doubt Helen Hunt was driving one of these. Was she? I didn't think so. So, that leaves only one question left to be answered -- what is this vehicle's true identity? Does the government know something we don't? Are the zombies coming? Because if they know the zombies are coming and they're not telling us, that is fucked the f up.
