Yeah, you guys are off.

They aren't just in the south, they're everywhere. I've got one in my town. The quality varies from bad (gravel roads, overgrown brush and weeds, crap trailers) to pretty good (paved roads, groomed grass, nice trailers, etc.)

Usually it's just for people that are in limited financial situations. Sometimes this means rednecks that dropped out of college and work fifteen hours a day mopping at McDonald's for minimum wage. Sometimes it means people that have been laid off and it's all the better they can do. It really varies.

And yes, lots of Jerry Springer material is produced from them, but not all people living in trailers are trash.
