San Diego County has filed a federal lawsuit against companies it alleges took over the market for fire trucks, leading to higher prices and slower rollouts to replace an aging fleet. The defendants allegedly acquired several smaller fire truck manufacturers and have effectively eliminated competition for the vehicles and their parts. This has led to trucks costing more than double what they used to and taking around one to four years to be delivered. Among the defendants are American Industrial Partners, which allegedly consolidated multiple manufacturers into one entity, REV Group, and Oshkosh Corporation, who controls the market with its subsidiary, Pierce Manufacturing, allowing its own subsidiary to charge high prices for its proprietary parts. The county's Board of Supervisors Chair, Terra Lawson-Remer, called this action part of a strategy to stop the "greed" companies.
