I didn't write it down but as I recall I believe it carries around 5000 feet of 5" along with a bunch of portable hydrants to allow units to get water along the lay.
These were built from retired 1970s vintage engines. They are primarily intended to provide water following an earthquake, the idea being that if the underground pipes are disrupted the hose wagons can lay in from the bay and one of the fire boats can pump the hoselay. San Francisco has had issues going back to 1906 of losing water following an earthquake, so has built in several redundant and alternative water systems.
San Francisco does not regularly use 5", 3" is their primary supply line.
Other cities in the area have made similar arrangements, the city of Oakland across the bay from San Francisco built similar vehicles on Ford Cargos following the 1989 Loma Prieta Earthquake and the city of Berkeley (next door to Oakland) bought some large volume trailer mounted pumps and a couple miles of 6" LDH.
