Trailers had been controversial since the 1930s. Aside from the sleek streamlined capsules that traverse the open road, these rickety boxes tend to be viewed as eyesores. Almost as soon as they were turned into permanent housing, many were associated with slums built on town dumps. As an object, the trailer is something modern and antimodern, chic and gauche, liberating and suffocating. Unlike the dull but safe middle American suburb, trailer parks contain folks who appear on the way out, not up: retired persons, migrant workers, and the troubled poor. This remains true today.
