This is an animal control body by Harbor Truck Bodies. It is essentially a highly modified service body with various size compartments for different size animals, plenty of ventilation and temperature control, which is especially important in the heat of the sun during most of the year in Southern California where this unit is in use by the City of Fontana.
As you can see by the photographs, it has special doors, expanded metal and solid metal partitions, vented panels, through compartments for larger animals, interior lighting, special coolers and exhaust ventilators, strobe lights, all LED exterior lighting, and this also has a Tommy Gate 1,000 lb liftgate.
