The aluminum body is 136 inches long and is equipped with seven enclosed lower body compartments together with top body locker compartments designed to accommodate backboards and a stokes basket. A hydraulic ladder rack on the right side of the body is used to store a 10-foot folding ladder, 14-foot roof ladder and a 24-foot extension ladder. The rear hose bed is protected with a two-piece aluminum tread plate hose bed cover.

Emergency warning lights consist of a full width Whelen Freedom LED light bar on the cab roof together with LED lights mounted both low and high around the perimeter of the body. Scene lighting is provided by a Super Vac Command Light, which is mounted on top of the raised roof cab together with side-mounted Whelen scene lights on the cab.

Tanker 3 is a 2010 Tatra model T-815 6x6 four-door cab chassis with seating for six personnel. A Cummins ISM engine, rated at 400 horsepower through a twin-disc six-speed automatic transmission, powers this unit. These rugged chassis are produced in Koprivnice in the Czech Republic and are used extensively overseas in commercial and military applications. The apparatus is built on a wheelbase of 188.5 inches with an overall length of 30 feet 9 inches. Tanker 3 has an overall height of 131 inches and is equipped with a central tire inflation system that can be automatically adjusted depending upon the terrain conditions. The heavy -duty chassis has a front axle rating of 17,637 pounds with a tandem rear axle rating of 39,682 pounds. The completed apparatus has a front angle of approach of 34 degrees with a rear angle of departure of 37 degrees.

The aluminum body is 161 inches long and is equipped with six lower body and two upper locker style compartments to accommodate tools and equipment. The upper body compartments are accessed through a pullout pool-style ladder. Apparatus warning lights consist of two Whelen Freedom mini LED light bars on the cab roof together with 14 Whelen 700 series LED lights around the perimeter of the apparatus. Weldon scene lights are located on each side of the body and at the rear for nighttime illumination.

The apparatus is equipped with a Waterous model 500-150 fire pump module rated at 50 gpm with a Aquis 2.5 Class A foam system. The fire pump is driven by a power take off and is rated at 500 gpm together with a 150 cfm air compressor. Fire pump discharges include five 1 3/4-inch discharges together with a bumper-mounted Task Force monitor rated at 500 gpm and a top-mounted Task Force remote-control deck gun rated at 500 gpm. Booster reels, each equipped with 150 feet of 3/4-inch hose, are located on each side at the front of the body. Tanker 3 carries 2,000 gallons of water with a 50 gallon Class A foam tank to supply the pump during operations. The water tank is equipped with a manually operated rear quick dump and direct tank fill valve for use during refill operations. This apparatus is an imposing vehicle and makes a good account of itself at any wildland incident.

The Maui County Department of Fire and Public Safety can be proud of its services to the community and in the future plans to continue its progressive approach to fire apparatus design. Appreciation is extended to Deputy Chief Robert Shimada who assisted in making arrangements for fire station visits and apparatus photographs.
