Seats five, and two emergency medical service (EMS) cabinets adorn each wall of the cab behind the driver’s seat. The EMS cabinets are accessible from the exterior through hinged doors between the cab doors. The cab and body are constructed of stainless steel with side roll and frontal impact protection, and AMDOR roll-up compartment doors as well as hinged compartment doors are part of the body package.

Self-contained breathing apparatus bottle storage is located above the rear wheel wells on each side of the body. The Pierce Command Zone advanced electronic and control system with WiFi headlines the truck’s electrical system.

The truck is powered by a Cummins X15 600-hp engine and an Allison fifth-generation   4500 EVS transmission with six speeds and push-button shifter. A Harrison Model 10.0 MAS-16R/D-11011/15/1 10-kW hydraulic generator is mounted above the torque box toward the front of the body.

The aerial is a rear mount, heavy-duty, 107-foot stick constructed of steel with a steel 1,500-gpm waterway and Stokes box on the right side. A Task Force Tips (TFT) Model Y5-EBA1-L30 electric monitor and a TFT Model M-ERP 1500 electric nozzle are featured. Tec Niq red LED lighting adorns the aerial for nighttime operations, and Fire Research Corporation SRA110-07 spotlights provide lighting on the tip of the aerial.

Duo-Safety ground ladders (one 1200A 35-foot, two-section; one 1200A 28-foot, two-section; one 850-A 20-foot wall; one 850-A 18-foot wall; one 875-DR 16-foot roof; one 775-A 14-foot roof with 7/8-inch hooks; one 701 Fresno 12-foot, two-section; and one 300-A Combo nine-foot) are stored in the torque box. A Duo-Safety 875-A-DR 16-foot roof ladder is mounted behind the boom panel on the left side of the aerial.

The warning lights include two Whelen Freedom IV-Q 21½-inch light bars on the cab corners with Whelen M4-, M6-, and WIONSMC-model LED lights located around the rig exterior. Whelen Model R316F Rota Beam beacons are mounted on the upper rear corners of the truck. Whelen I2CSM traffic-directing lights are individually mounted on the upper side (left and right) and across the rear end of the body. Scene lighting is provided by Whelen Pioneer PCPSM2 lights on each side of the body toward the front and PCPSM1 lights toward the rear on each side.

Hi-Viz Model FT-MB-2.18-FT lights are mounted on the cab adjacent to the light bars. Hi-Viz FT-MB-24 TRGWA-FT lights are mounted on the roof between the cab and crew doors. Audio warning devices include a flush-mount Federal Q2B through the center of the bumper and a Whelen Model 295SLSA1 electronic siren module with two Whelen SA315P speakers mounted through the right front bumper.

All DFR trucks are “dry” trucks (no pump or tank).
