The company operates as a for-profit limited liability company and competes uniformly under small business designations across its federal footprint.

Custom Trailers Builder operates as a standalone prime with no identified parent contract vehicles, GWACs, IDIQs, or BPAs. Each award is a direct purchase order from a requesting federal agency. The company does not subcontract and has not partnered as a sub on recorded federal contracts. Performance occurs primarily at the Norco, California headquarters, with delivered trailers deployed to customer locations across the continental United States, Guam, Japan, and other overseas military installations. Recent examples include trailers delivered to Fort Moore, Georgia; Beltsville, Maryland; Groton, Connecticut; Yigo, Guam; Tracy, California; and Honolulu, Hawaii.
