So please let me know if there is something like this already in the game but I have not seen something close yet.
In my area we use "mini rescue or utility trucks" converted into medical trucks. All fire stations paid or volunteer in upstate New York love these things. I have also seen many of these across the country but don't know their feelings. It allows fire personal to respond to medical calls without taking out the big engine and some even outfit these to be rescue vehicles.
What I am proposing is a vehicle like this to respond to medical calls if the player wants to and have it help there. It could help treat patients without a ambulance on scene and maybe even clear the scene. In my area these vehicles are allowed to accept "denial of transport" on all non - serious calls. I am unaware if the current chief or utility vehicle can actually clear calls without a ambulance being on scene. I have attached a photo of what one of these may look like.
Please let me know what you think.
