Custom Trailers Builder LLC

Custom Trailers Builder LLC, a minority-owned, Asian-Pacific American-owned small disadvantaged business based in Norco, California, manufactures custom trailers and specialized mobile equipment for federal agencies as a prime contractor under total small business set-asides across all major awards. The firm is a for-profit limited liability company competing exclusively in set-aside categories, with all 42 prime purchase orders designated for small business participation (or in two cases, unrestricted full-and-open competition).

Custom Trailers Builder LLC delivers mission-specific trailer systems across a portfolio spanning truck-trailer manufacturing (25 awards), travel trailers and camper manufacturing (5 awards), and miscellaneous fabricated metal and specialty equipment (6 awards). Representative work includes a $243,000 firm fixed-price contract from the Army's Training and Doctrine Command for 500-gallon stainless-steel water trailers certified for drinking water use, a $218,360 fuel-tank trailer unison buy from Army Sustainment Command, a $156,000 enclosed car trailer for Air Combat Command, a $142,000 intermodal cargo system trailer for the Coast Guard supporting emergency response in Hawaii, a $131,014 order for four landing signal officer carts from Naval Air Systems Command, a $129,782 mobile latrines unison buy from TRADOC, and a $85,955 decontamination trailer for Air Combat Command.

Customer concentration clusters around Department of Defense commands. The top five customer agencies by potential value account for 52 percent of combined dollars: Army Training and Doctrine Command leads with four awards totaling $449,000, followed by Air Mobility Command ($285,000), Air Combat Command ($242,000), Coast Guard ($154,000), and Naval Air Systems Command ($131,000). By award count, TRADOC, Army Test and Evaluation Command, Army Installation Management Command Southwest Region, and Air Force commands dominate the customer base across 25 distinct federal agencies served. The vendor operates as a pure prime contractor; the source contains zero subcontract awards.

Activity peaked in 2023 (16 awards) and has declined to six awards in 2025 and two in 2026 year-to-date. Over the past four years, combined potential value totaled $2.4 million with $2.4 million obligated (100% execution rate). Only one award carries an ultimate completion date within the next twenty-four months, indicating minimal near-term recompete exposure. Purchase orders consistently range from $14,500 to $243,000, with a median in the $40,000 to $85,000 band. The vendor does not sit on any GWACs, BPAs, or agency-wide IDVs; all work flows through individual purchase order solicitations, primarily from regional Army and Air Force commands, the Coast Guard, and smaller civilian agencies. Primary NAICS classification is 336212 (Truck Trailer Manufacturing), with secondary work across travel trailers, heating equipment, and industrial machinery.
