This is an ambulance I have built recently. In the front it is 6 studs wide then in the back it is 8 studs wide. The ambulance can hold 3 medics (minus the driver) and 2 stretchers/ gurdies. If anyone has a similar design do not sue me I am not stealing credit or anything. Unfortunately I still have to take the pictures of the real models because my LDD is not working still.
