Worst Travel Trailers

I have always heard that there was a brand of trailers that the con artists sell. Supposedly, they look good but are junk underneath. The story goes that they shine these things up and sell them to the unsuspecting as top of the line rigs. Anything to this, or just another urban legend?

The reason I ask is that five "No name" trailers with big "For Sale" signs on them were in a campground in Ohio that I was visiting. I could not even find the brand on the Internet.
