Truck 31 was purchased by the Arcadia Fire Department in 1978 and was the last Snorkel built by Crown Coach.  She is powered by a Detroit Diesel 8v92 motor with an Allison Automatic transmission, equipped with an 85 foot Snorkel and carries serial number F1804.
This apparatus was not only the last Snorkel built by Crown, it was also the only Snorkel, or "truck", built using the new wide cab design.
