Squad units are trucks (like a 550 chassis) with lots of compartment space rather than tank/pump. There's a lot of equipment, far more than would fit in a car.

"Fire cars" (SUVs really) are for moving chiefs, not equipment. There is a lot of variability in US fire departments. The kit for a city department is very different from the kid for a rural district like mine.
