Airport fire trucks are much larger and carry up to six times more water than normal fire engines. Their larger tires and higher ground clearance allows them to operate both on and off runways.
This Titan comes with a 1500 gallon water tank and a 200 gallon foam tank. Foam and water are mixed and sprayed though a turrret on the roof and a bumper-mounted turret. In addition, two handlines are stored in the grey compartments on the sides.
