I know that I do a lot of work beta testing fire apparatus in another game I play but looking through this topic you have some great ideas, and the mod look slike its coming along well I think that there are a couple other things that should be added such as a more realistic dozer like the one in this link https://www.youtube.com/watch?v=E4TfSUdVt8U and that the dozer transporter should be similar to the one in the link as well for more realism, after all it seems like your trying to make the game americanized instead of European. As well I would also add in more real life like tone outs for the calls in freeplay, captains on the engines, and with those captains and chiefs who give the commands have a command option for calling out units in terms of alarms like a box alarm requesting say a whole task force (2 engines, 1 ladder) then each additional alarm requesting either another task force or a light force (1 engine, 1 ladder), and if its a captain calling it in have the ability for him to call in a battalion chief.
