Standard low rate production effects. Equipment like fire trucks are full of weird, low volume things made by a few, or only one shop somewhere, built exclusively to order, with long lead times. A fire truck is simultaneously a mobile power station, a mobile high pressure water pump, a mobile communications base station, and a high performance all-terrain, all-weather vehicle. It has to do all of that without killing any firemen, so there are very high liability costs factored in. Also, every major department has a collection of hang-ups about how a fire truck is supposed to function and what it's compatible with, so there is no way to scale production. The consolidation of suppliers for all of this is also a contributor to cost and delivery time. That problem is endemic throughout Western economies.
