Trailer Parks are a wholly U.S. phenomenon, and are very uncommon in New England. The idea of a "suburban" concentration of lower-income people simply does not really exist in New England. Lower income people live in cities (apartments, row houses) or in rural New England (
cottages similar to this). One could argue it's a step back from actual trailer parks, as running water in the most rural of New England settlements is not a guarantee, and by and large wood-fired stoves are the main heat source for a vast number of New England's rural population. Some areas go without electricity, but 99.5% of New England has access to it.
