The American LaFrance Truck 10 was assigned to the Department in 1960 as Truck 1 then assigned as Truck 8 in 1968 and then assigned as Truck 4 in 1973. Truck 4 was assigned as Reserve in 1980 when Truck and Engine 4 were disbanded. This model was the first fully loaded relief aerial company.
This 100 Foot American LaFrance steel aerial was powered by an inline 6 cylinder Continental Gasoline engine with manual transmission. The fabricated cab and tiller enclosures were installed in 1968/69.
