ELECTRIFIED FIRE FIGHTING VEHICLE

An electrified vehicle includes a chassis having a longitudinal length of at least 20 feet and an energy storage system. The energy storage system includes an enclosure coupled to the chassis, a battery pack positioned within the enclosure, a power distribution system positioned within the enclosure, a first wiring harness positioned entirely internal to the enclosure where the first wiring harness electrically couples the battery pack to the power distribution system, and a second wiring harness. A first portion of the second wiring harness is positioned internal to the enclosure and a second portion of the second wiring harness is positioned external to the enclosure. A maximum external length of any cable of the second wiring harness external to the enclosure is less than 25% of the longitudinal length.
