1991 GMC Topkick E-One Rescue 7-Crew Truck

• The Foundation: The GMC Topkick serves as a robust, highly reliable platform widely favored by municipalities. 
• The Engine: Power is delivered by a Caterpillar 3116 6.6L inline-6 turbocharged diesel engine. This mechanical-injection motor is highly sought after for emergency applications due to its total lack of complex electronic computer systems, making it highly reliable and straightforward to fix. At 250 horsepower, it is tuned toward the higher end of its power scale to haul the massive weight of a fully loaded rescue body.
• Transmission: The 4-speed automatic transmission (likely an Allison medium-duty series) enables smooth operation under emergency response conditions, ensuring the driver can focus entirely on navigation without manual shifting.

• Construction: Built using E-ONE’s signature extrusion-bonded aluminum framework. This design provides exceptional structural rigidity while remaining lightweight, preventing rust, and maintaining a low center of gravity.
• Personnel Capacity: The truck safely seats 7 persons total. The rear walk-in box features specialized bench seating for 5 rescue personnel.
• Crew Comfort & Ready-State: The bench seats include integrated bottle holders designed to secure Self-Contained Breathing Apparatus (SCBA air packs), allowing firefighters to gear up while en route. Dedicated rear heat & A/C ensures the crew environment is strictly climate-controlled, mitigating heat exhaustion or extreme cold before they arrive at an incident. 

• Onan 7.5RV Genset: A commercial-grade 7.5 kVA diesel generator that outputs 120/240V single-phase power at 31.3 amps. This provides massive auxiliary electrical capabilities to run high-powered rescue tools, scene lighting, or medical devices.
• Fuel Integration: By drawing diesel fuel directly from the truck’s main fuel system, it completely eliminates the need for a separate gasoline tank, streamlining refueling operations and ensuring long-duration scene power.
• Retractable Power Reel: Equipped with a cord rewind mechanism, this system allows operators to rapidly deploy power lines to the scene and quickly retract them when clearing the call.
• Master Battery Disconnect Switch: A critical safety feature for emergency vehicles. It cuts off all electrical draw when the vehicle is parked inside the station, preventing parasitic battery drain from radios, computers, and emergency lights.

• The Mechanics: Manufactured by Air Options Inc., this high-pressure system consists of four 6,500 psi storage cylinders connected in a "cascade" configuration.
• Operational Purpose: A cascade system allows crews to refill empty SCBA breathing bottles directly at the scene of a working fire or technical rescue. By utilizing pressure differentials across the four storage bottles sequentially, it maximizes efficiency and allows the team to sustain long-term interior operations without returning to the station for air.
