Mystery water truck helps SFFD extinguish box van fire

(For licensing or usage, contact [email protected]) A box van somebody had been living in went up in flames on April 17, 2024. As I was filming the conflagration, a water truck with no markings suddenly pulled up and doused the burning vehicle with water. Was this an SFDPW vehicle working in concert with SFFD? Or did the truck's operator do this helpful thing with no forethought or orders to do so? Regardless, it's a wonderful moment, unexpectedly caught on video. EDITED TO ADD: Twitter user @nicedeela says the operator of the water truck is her husband, Julio Parra, owner of JP's Water Truck Services. She says he sprays construction sites for dust control, and this is the third fire he's helped to extinguish.
