This from Bill Friedrich:

Approved at the Palatine City Council earlier this week, the Palatine FD placed an order for a Spartan Gladiator ELFD 20-inch raised roof chassis with a Marion Body Works 20-foot walk-around heavy rescue squad. Delivery is expected in late 2013

The old squad will be placed in reserve once the new vehicle arrives and is placed in service.
