I am gonna check on this. From my understanding, the "Quint" on this game is able to act as both an Engine and Truck Company. Have you tried sending a Quint on the call? Or are you referring to the straight Platform Trucks being able to handle the call?
I am talking about a platform truck. I'm building up Chicago so they don't particularly use quints and most of my engines are already on calls when it comes in. I don't see the point of removing them as a whole because if a tree is actually blocking a roadway or interfering with traffic, it is more of a fd/pd call more than public works. I'm just going from experience from the department I work for.
