Those are just scare tactics. Current regulations make trailer living much safer than "you're gonna die" TV meteorologists would have you think. They're required to be tied down well enough they can withstand fairly high winds, probably EF1-strength tornado. That doesn't mean I'm going to hang out in my trailer house with any tornado headed my way, but the media makes it sound lots worse than it really is. That's how they get ratings. I'm fortunate enough to have an underground shelter nearby.
