This from Isaac Main:
I saw a post regarding Caterpillar purchasing a quint for one of their Peoria-area locations I’m not sure which location that truck is headed to, but I thought I’d share some pictures of the equipment they have at the Peoria Proving Ground. I don’t know any details beyond what is obvious in the pictures. The truck is a 4×4 Peterbilt/Alexis, the “ambulance” is a Chevy Suburban, and the HAZMAT truck is a 4×4 Ford F-250.
