From Naperville Professional Firefighters Facebook page:

Today (7/6/20) is an exciting day for the Naperville Fire Department! Truck 10 officially goes into service, replacing Engine 10 as the front line fire supression vehicle for station 10.

At the same time, this change will move Truck 5 into “reserve” status and station 5 will switch into Engine 5.
