A roll-up or swing-style rear door makes loading and unloading efficient, especially when paired with a liftgate.
Interior amenities include cushioned adjustable seats, wide legroom, and easy-to-read instrument panels. Options like tilt steering, air conditioning, and cruise control add convenience. With plenty of cabin storage and comfort, it’s a practical design for long working hours.
Engine and Performance Insights
At the heart of the C6500 is a powerhouse Duramax 7.8L engine, delivering ample torque for steep inclines and full loads. With 260 to 300 HP under the hood and paired with an Allison automatic transmission, the truck glides through gear shifts smoothly—even under pressure.
This combo offers impressive towing and hauling capabilities, supporting both local deliveries and long-haul applications. Its responsive powertrain reduces driver fatigue and ensures the truck can handle tough tasks daily.
Optimized Box Size: Why 13’6” Hits the Sweet Spot
The 13’6” cargo box offers a versatile size for urban delivery and regional use. Its interior volume is enough for transporting furniture, commercial goods, equipment, or even custom-built mobile services.
Features typically include:
- Hardwood or reinforced steel flooring
- E-track or tie-down rails
- Interior lighting
- Rear liftgate (optional, tuck-away or rail-type)
This balance between capacity and maneuverability makes it popular among moving companies, contractors, and mobile service providers.
Safety and Control Features
The C6500 offers both air and hydraulic brake options depending on the configuration. Air brakes are ideal for heavier-duty work, while hydraulic brakes offer simpler maintenance.
Other safety features may include:
- DOT-compliant lighting and reflectors
- Backup camera (add-on)
- Power mirrors and wide-angle side mirrors
- Reinforced bumper and underride protection
These enhancements help improve road visibility and meet regulatory standards for commercial operation.
Handling and Suspension Setup
The suspension can be equipped with heavy-duty spring packs or air ride systems. Spring suspensions provide rugged performance on rough roads, while air suspensions offer a smoother ride and help preserve fragile cargo.
Power-assisted steering and wide turning angles allow for nimble navigation, even on narrow city streets.
Fuel Efficiency and Maintenance Overview
With an average fuel economy of 8–12 MPG, the C6500 is reasonable for its class. It features a large 60–80 gallon diesel tank, allowing fewer refueling stops and extended drive times.
Maintenance costs are moderate thanks to the engine’s simple design compared to newer emissions-heavy models.
Key Maintenance Tips:
- Oil changes every 5,000–7,000 miles
- Brake inspections and fluid top-offs
- Monitor injector performance and electrical systems
Well-maintained models can easily exceed 300,000 miles, proving their value over the long haul.
