1. A quint configuration fire apparatus, comprising:
- a chassis;
a body assembly coupled to the chassis and having a storage area configured to receive a ground ladder and a fire hose;
a pump coupled to the chassis;
a water tank coupled to the chassis;
a ladder assembly including a plurality of extensible ladder sections, the ladder assembly having a proximal end that is coupled to the chassis;
a single front axle coupled to a front end of the chassis and a single rear axle coupled to a rear end of the chassis, wherein the single rear axle comprises either;
a single solid axle configuration extending laterally across the chassis, or a first axle having a first set of constant velocity joints and a second axle having a second set of constant velocity joints, the first axle and the second axle extending from opposing lateral sides of a differential;
wherein the ladder assembly is extensible to provide a horizontal reach of at least 100 feet and a vertical height of at least 105 feet, wherein the ladder assembly is configured to support a tip load of at least 750 pounds, wherein the water tank is configured to contain at least 500 gallons of water, and wherein the center of gravity of at least one of the chassis, the body assembly, the pump, and the water tank are positioned to counterbalance a moment generated by the tip load with the ladder assembly extended to the horizontal reach of at least 100 feet.
