Top private fleets by trailer. body stock show shifts in retail, food, and construction

Trailers and truck bodies are the backbone of the commercial vehicle industry, the equipment that transports cargo across the country or helps fleets do important jobs in construction, utilities, and other industries. Trailer and truck equipment types include dry van, flatbed, refrigerated, tank, lowboy, dump, and more. While the top two fleets remained the same as last year in the The 2026 FleetOwner 500: Private list, the rest of this Top 10 saw minor ups and downs, along with a few new entries.

The annual FleetOwner list ranks the most prominent private carriers in the U.S. by total registered power units. FleetOwner breaks these fleets down into categories, either by equipment or by the fleet's main cargo type or segment.
