Ambulance 579 was returned to service in early September, 2020 after being being remounted, an operation designed to extend its life instead of replacing the entire rig.

The ambulance was towed to SIV Ambulances in Langhorne, PA in mid-May, 2020 to be fitted with a new, 2121 Ford F-450 chassis.  Remounting, where the worn-out chassis is replaced while the costly ambulance box is reused, is a prudent practice that is far more cost-effective than replacing the entire ambulance.
