Equipment might likely vary from one trailer to another. When a trailer is installed in a pubwan trailer park, a location on the perimeter of the occupied portion of the park is chosen. The location is chosen to maximize (weighted) distance between the incoming trailer and trailers whose combination of services offered is most similar. The raw information needed for determining that location is public information, as is all information stored on pubwan. The chosen location would likely have from one to three neighboring trailers. Hookups are made with these trailers.

In addition to hookups for services provided by or consumed by a trailer, a wide variety of "passthrough" hookups would ideally be included in a typical trailer. These would be simply lines (tubes or wires) connecting fixtures on one side of a trailer with those on an adjacent side. Some would also include small amounts of processing, such as amplifiers, pumps, etc.
