Hy MattMck, welcome, MikeB, a member here had a complete firetruck like yours for many years, I'm sure when he sees this he will chime in. There is always a lot of extra equipment on firetrucks, depending on how diligent they were when they removed the fire body there may be unnecessary equipment still left on the truck. Some firetrucks even tapped into the engines vacuum system to assist in priming the pump. As to the maintenance manuals, there is lots of good information in them, just make sure you get a full manual and not a supplement. Happy Independence Day!
