This from Drew Smith:
I thought I’d share some history of Prospect Heights tankers. Before the decommissioning of the 1994 Spartan/S&S tanker, Prospect Heights operated a 1968 Ford/Darley tanker. That tanker had a Darley two-stage 750 GPM pump and a 1500 gallon tank. In 1989 that tanker was sent to Monroe Truck where a new, 1500 gallon wet-side tank was installed. Prior to the new tank, Darley overhauled and rebuilt the pump. After delivery from Monroe Truck, members of the PHFD plumbed crosslays and installed new warning lights and had a local provider apply graphics. That tanker served a total of 26 here at the PHFD. It was then sold to the Mountain, WI FD where it served several more years. It is currently owned by Michael Zahnen, owner of The Zahnen Companies in Michigan, a Spartan EV dealer. Mike was also a member of the PHFD more than 30-plus years ago.
