In my local fire department we have this truck, it can go super high, and is just SUPER high tech. I think that SCFD should have this truck, as it can go to hard to reach rooftops and other things, also has a big basket that has a ramp. Here is a link: https://www.youtube.com/watch?v=HLj40_6yFOo
Another suggestion for the fire department is a snozzle truck, It is just a engine truck with a boom arm that has a hose and a little poker to ventilate roofs. the poker would not be Colidable, so it could be used for rp purpose, this truck would also reduce the danger of firefighters getting burnt.
