This from Phil Chase:

Hi,

I’m a long time reader of your blog, first time responding to anything.
I just thought I’d let you and your readers know that on Brindlee Mountain Fire Apparatus (https://www.firetruckmall.com/RecentDeliveries.aspx) Open 4 Business Productions, LLC — NBC’s Chicago Fire is buying a chassis. I wonder if it is for the new squad?
Sold to :Open 4 Business Productions, LLC — NBC’s Chicago Fire
Fire body is being removed – Cab and chassis only
