I also made a few changes.
At Station 1
I replaced Engine 4 with a Tanker
At Station 2
I replaced Engine 2 with Forestry 1 and I replaced Engine 3 with a Tanker as well.
I found that with out a lot of Hydrants on the map each department would have it's own tanker within it's halls. To continually call a mutual Aid when fighting a fire and having to call in a tanker each time is a waste of money.
I am also looking at removing some units from hall 1. While it is nice having all these units there I if this is a volunteer hall they must have some pretty big industry (must be off map) for them to own so many trucks.
I love the mod though and am looking forward to seeing future releases.
