UNSPSC 25181611 Dolly trailer (Commodity) covers trailers and specialized cargo-handling bodies that state and local governments procure for fleet operations, utility services, and specialized transport. Recent activity shows municipalities purchasing enclosed and utility trailers for one-time acquisitions, heavy-duty utility service bodies for installation on purchased chassis, and specialized upfit bodies such as animal protection units for law enforcement. The code encompasses both standalone trailer procurement and custom body fabrication and installation on cab-and-chassis units, with work ranging from simple enclosed trailers to complex service bodies requiring full mechanical and electrical integration, emissions compliance, and DOT certification. Issuing bodies include city procurement offices and county departments managing municipal vehicle fleets; the City of Lubbock, City of Albuquerque, City of Tucson, City of North Las Vegas, County of Sacramento, and Yuma County, Arizona appear in the recent record, suggesting mid-sized to large municipal fleet operations as core buyers.

Geographic activity concentrates in Arizona and Texas, with additional procurement in California and Nevada. The City of Tucson issued an RFP for heavy-duty utility service bodies with an estimated annual spend of $250,000 to $300,000 and an evaluation weighting 45% method, 30% qualifications, and 25% price; the response deadline was August 15, 2023 (now closed).
