If you want to create Detroit mod there should always be no ambulances available like in reality. Detroit is the worst fire dept. in the entire country mostly due to budget cuts and not because of the personnel.
I feel as if the battalion-chief car (it's a Ford I believe) is huge in comparison to the ambo and the police Crown-Vics. It's as big as the ambulance, isn't it?
That's a cool truck. Do the Australian fire engines always have orange lights on the back even if they have red/blue lights on the front like the engine1 above?
