Towing and Payload: Comparing International CV Series Pickup Truck Variations | Commercial-Grade Strength, Versatile Configurations, and Job-Ready Capability for Growing Businesses
Picture this: you’re behind the wheel of an International CV Series, the diesel engine humming confidently as you hook up to a loaded equipment trailer—the integrated trailer brake controller is at your fingertips, the air ride suspension levels out the load, and you know without a doubt that this truck was built for exactly this moment.
If you’re searching for a medium-duty truck that combines genuine commercial-grade capability with modern driver comfort, the International CV Series deserves your attention. Unlike modified heavy-duty pickup trucks, the CV Series was engineered from the ground up as a purpose-built commercial vehicle . Whether you’re running a towing business, managing a landscaping fleet, or need a reliable platform for a specialized upfit, understanding the towing and payload variations across different CV Series configurations is essential for making the right choice.
Key Takeaways
- Class 5/6 Designation: The CV Series occupies the medium-duty truck space, offering significantly more capability than even the heaviest consumer pickup trucks .

Understanding the International CV Series: Purpose-Built Medium-Duty Capability
The International CV Series, introduced in late 2018 as the successor to the TerraStar, represents Navistar’s entry into the Class 4-6 truck segment . But here’s what makes it genuinely different from the heavy-duty pickup trucks you’re familiar with: it’s the only truck in its class designed, distributed, and supported by a manufacturer that specializes exclusively in commercial diesel trucks .
For business owners who’ve been pushing consumer-grade trucks to their limits, the CV Series offers a welcome upgrade. It’s built on a high-strength, low-alloy steel frame with 50,000 PSI yield strength and features a straight rail design with no rivets on the top flange . This engineering choice isn’t just about strength—it’s about making body installation simpler and more secure.
The 6.6L Diesel Heart
At the core of every CV Series is the International 6.6L diesel engine, delivering up to 350 horsepower and between 700 and 750 lb-ft of torque depending on the model year . This powerplant was specifically chosen for its balance of capability and efficiency in medium-duty applications. Paired with an Allison automatic transmission—available in several series including 1700, 1750, 2700, and 2750—the drivetrain is built to handle the stop-and-go demands of vocational work .
The Allison transmission in the CV Series can be spec’d with various vocational codes (HS, RDS, EVS, MH) to match specific job requirements, ensuring optimal performance whether you’re hauling heavy loads or navigating tight urban streets .
Towing Capacity and Payload: The Numbers That Matter
When you’re comparing International CV Series variations for sale, understanding the relationship between configuration and capability is crucial. Let’s break down what these numbers actually mean for your business.
Gross Vehicle Weight Rating Explained
The CV Series offers Gross Vehicle Weight Ratings that vary based on drivetrain and configuration :
| Configuration | GVWR Range | Best Suited For |
|---|---|---|
| CV515 4×2 | 15,000 – 23,500 lbs. | Highway towing, delivery, lighter vocational applications |
| CV515 4×4 | 17,500 – 23,000 lbs. | Off-road job sites, utility work, snow plow operations |
Notice that the 4×4 configuration actually has a slightly lower maximum GVWR than the 4×2. This is typical in medium-duty trucks—the additional weight of the four-wheel-drive components reduces the available payload capacity. For operations that primarily work on paved surfaces, a 4×2 might actually offer more usable payload.
Real-World Towing Example
To make these numbers concrete, consider a 2020 International CV515 4×4 that recently sold at auction . This particular truck was equipped with:
- 6.6L V8 diesel engine
- Automatic transmission
- Four-wheel drive
- GVWR of 22,500 lbs.
- Front GAWR: 7,500 lbs.
- Rear GAWR: 15,000 lbs.
This truck was configured with a Versalift VST52I bucket body—a specialized upfit for utility work. The same chassis could easily accommodate a wrecker body for towing operations, a dump body for landscaping, or a refrigerated box for delivery services .
When shopping for a used CV Series, look closely at the door jamb sticker for the actual GVWR and GAWR figures. These numbers tell you exactly what that specific truck can handle, regardless of how it was originally equipped.
The Evolution of Medium-Duty Trucks
The International CV Series represents the culmination of decades of medium-duty truck development. Understanding this evolution helps explain why the CV Series is such a capable platform.
- Early 1900s – Trucks are simple, open-cab platforms with minimal payload capacity. Custom bodies are built by local craftsmen.
- 1950s – Mass-produced medium-duty trucks emerge with standardized frames. Vocational bodies become more common.
- 1980s – Diesel engines become dominant in commercial applications. Turbocharging improves power and efficiency.
- 2000s – Electronics transform the driving experience. ABS brakes and electronic engine controls become standard.
- 2015 – International discontinues the TerraStar, leaving a gap in the Class 4-5 segment .
- 2018 – International CV Series launched, bringing modern technology and driver comfort to the medium-duty market .
- 2020 – CV Series gains traction in vocational applications including towing, utility, and emergency services.
- Present – The CV Series continues to offer the only Class 5/6 truck backed by a nationwide commercial dealer network .
Configurations That Matter: Choosing the Right CV Series for Your Needs
The CV Series isn’t a one-size-fits-all truck. With multiple cab configurations, wheelbase options, and drivetrain choices, you can tailor the truck to your specific application.
Cab Configurations
- Regular Cab: Available with wheelbases from 165 to 243 inches, ideal for applications where crew seating isn’t needed .
- Crew Cab: Wheelbases range from 175 to 235 inches, providing space for a work crew plus equipment storage .
Drivetrain Choices
The 4×2 configuration is lighter and offers slightly higher maximum GVWR, making it ideal for highway towing and delivery applications where traction isn’t a concern. The 4×4 configuration adds a Meritor 3203 two-speed, gear-driven transfer case with electric shifting controls and an optional skid plate for off-road protection .
For snow plow operations or utility work in rough terrain, the 4×4 configuration with the available skid plate is worth the payload trade-off. For straight highway towing, the 4×2 will serve you well and potentially offer better fuel economy.
| Feature/Model Insight | Best For | Availability | Key Material/Tech | Capability Impact |
|---|---|---|---|---|
| CV515 4×2 | Highway towing, delivery, paved-site work | Standard | 50,000 PSI frame, Hydromax brakes | Higher max payload (23,500 lbs. GVWR) |
| CV515 4×4 | Off-road job sites, snow plow, utility | Standard | Meritor 3203 2-speed transfer case | Added traction, slightly lower GVWR (23,000 lbs.) |
| Air Ride Suspension | Fragile cargo, driver comfort | Optional (4×2 only) | International Ride Optimized Suspension | Smooth ride, height flexibility |
| Trailer Brake Controller | Towing operations | Optional | Integrated dash-mounted controller | Confident trailer control |
Real-World Impact: The CV Series in Action
For towing and recovery operators, the CV Series offers distinct advantages over modified consumer trucks. The straight frame rail design provides a stable platform for wrecker bodies, while the available air ride suspension helps protect both the truck and its cargo from road shocks .
The Hydromax Braking Advantage
One feature that sets the CV Series apart is the Hydromax braking system, which includes 4-channel ABS, traction control, electronic stability control, and trailer sway control as integrated features . For anyone who’s ever felt a trailer start to sway on the highway, that trailer sway control isn’t just a convenience—it’s a safety feature that can prevent a loss of control.
Always remember: Even with advanced braking systems and trailer sway control, proper weight distribution and secure loading are your first lines of defense against towing incidents.
