Nice example of the Econic, illustrating the bus door for the crew.
This low profile chassis with its easy access three seat cab was originally conceived for garbage trucks and other municipal rigs which needed a three person cab with easy egress/ingress for stop-start types of applications.
But it soon proved useful for aerial fire trucks, because it had a low center of gravity and could accommodate ladders or booms without being too high.
The cab has been occasionally used for pumpers and rescue squad trucks, but does not really lend itself to a full crew cab configuration unless a really low overall height is necessary...
