Goodness, my department has dozens of different vehicles. From multiple engines types, ladder truck types, bambulances, chiefs & safety officer buggies, the bombers EOD vehicle (bomb disposal), boats, inflatable boats, foam trucks, water tankers, airport Crash Rescue, Heavy Rescues, Light plants, and I know I'm forgetting some probably.
Don't forget Quints (which are both ladder and engine trucks, not a fan) and tiller trucks (which are the most fun vehicles in the history of mankind).
