Extreme Utility: Finding a Pre-Owned International HV Series 4×4 for Sale | Save $100k vs. New, Unlock Off-Road Capability, and Specs for Dump, Water, and Expedition Builds
You’re standing on a job site that’s been soaked by three days of rain, watching a loaded dump truck spin its tires and sink into the mud, and you think to yourself—there has to be a truck that laughs at this stuff. There is. It’s the International HV Series 4×4, and finding one used might be the smartest money you’ll spend all year.
TL;DR
The International HV Series 4×4 is a severe-duty vocational truck built to work where pavement ends—construction sites, off-road utility jobs, and even extreme overland expeditions. Buying pre-owned can save you $100,000 or more compared to new, with clean used examples ranging from $85,000 to $175,000 depending on age, mileage, and configuration . These trucks feature Cummins power (B6.7 or L9), Allison automatics, locking differentials, and air brakes with ABS . You’ll find them as dump trucks, water trucks, cab & chassis, and even expedition campers . The HV507 4×4 with the 33,000 lb GVWR is the sweet spot for most buyers, but 6×6 variants exist for extreme loads . Whether you need a municipal workhorse, a construction site survivor, or a global expedition platform, a used HV 4×4 delivers capabilities that pickups can only dream about—often for less money than a loaded Ford F-450.
Key Takeaways
- Massive Savings: New HV507 4×4 trucks list around $116,000–$158,000; comparable used models (2020-2023) sell for $85,000–$175,000, with most under $100,000 .
- Powertrain Matters: Look for Cummins B6.7 (250–325 hp) for lighter duty or Cummins L9 (300–370 hp) for heavier work. Both mate to Allison automatics .
- GVWR Ratings: The HV507 typically offers 33,000 lbs GVWR (Class 7), while 6×6 variants can reach 60,000 lbs .
- 4×4 System Features: Factory locking differentials, dual-range transfer cases, and air brakes with ABS are common—verify they work before buying .
- Body Configurations: Used trucks appear as dump bodies, water trucks, cab & chassis, chipper trucks, and even expedition campers .
Understanding the International HV Series 4×4: What Makes It Extreme
The International HV Series (Heavy Vocational) is the successor to the WorkStar, and it’s built on a galvanized steel cab with severe-duty frame rails . But the 4×4 versions? They’re a different breed entirely. These trucks come from the factory with four-wheel drive engineering, not aftermarket conversions. That means the transfer case, front axle, and driveline are engineered as a system from day one.
The HV507: The Sweet Spot
Most of the used market centers on the HV507 model, a Class 7 truck typically rated at 33,000 lbs GVWR with a 14,000 lb front axle and 20,000 lb rear axles . This configuration gives you:
- Cummins B6.7 or L9 diesel power
- Allison 3500 RDS or similar automatic transmission
- Air brakes with ABS
- Locking differentials (often rear, sometimes front)
- 197–221 inch wheelbase options for various bodies
The B6.7 Cummins in the 250–325 hp range is perfect for municipal work, light dump duty, and utility applications . If you need more grunt, the L9 with 300–370 hp handles heavier loads and tougher terrain .
Do you need the extra horsepower, or will the fuel savings of the smaller engine serve you better?
The 6×6 Variant: Extreme Capability
For the truly insane applications—think 60,000 lb GVWR water trucks or global expedition vehicles—International offers the HV507 in 6×6 configuration . These beasts feature:
- Three axles, all driven
- 40,000 lb+ rear axle ratings
- Cummins L9 power
- Air brakes with ABS
These trucks are rare on the used market, but they appear. One 2020 HV507 6×6 water truck with just 14,276 miles recently listed for $172,500—a fraction of its new cost .
Where to Find Pre-Owned HV 4×4 Trucks
The used market for International HV 4x4s is specialized but active. Here’s where to look.
Commercial Truck Dealers
Major truck centers like Rush Truck Centers and Custom Truck One Source regularly stock used HV507 4x4s . These dealers often have multiple locations and can source trucks from across the country. The advantage? They typically offer:
- Inspected and serviced trucks
- Clean titles and documentation
- Financing options
- Shipping coordination
Online Marketplaces
Commercial Truck Trader lists dozens of HV507 trucks at any given time . You’ll find new and used examples from dealers and private sellers across the US. Recent listings show:
- 2020 models with 20,000–30,000 miles priced $84,500–$89,500

Salvage and auction sites can offer bargains, but you must inspect personally or factor in significant repair costs .
Expedition Vehicle Market
Here’s a wild twist: the HV 4×4 chassis has become a favorite for extreme overland expedition builds. A 2025 HV507 4×4 Bliss Mobil camper recently sold for $465,000, proving that these trucks can go anywhere—for a price .
If you’re looking for a used expedition-ready HV, forums like Expedition Portal occasionally list custom builds .
What to Look For When Inspecting a Used HV 4×4
Buying a used severe-duty truck requires a different approach than buying a pickup. Here’s your checklist.
Frame and Undercarriage
The HV features a huck-bolted frame that’s designed to last, but inspect carefully for:
- Cracks near suspension mounts or body attachment points
- Rust—surface rust is normal, but deep pitting or section loss is trouble
- Bent or twisted rails—evidence of severe overloading or accident
4×4 System Verification
This is critical. You need to confirm:
- Transfer case operation—does it engage smoothly in both high and low range?
- Locking differentials—do they engage and disengage as designed?
- Front axle—check for leaks, unusual noise, and proper engagement
- Driveline—u-joints, carrier bearings, and yokes should be tight
Would you rather discover a $5,000 transfer case repair before or after you buy?
Engine and Transmission
The Cummins engines in these trucks are generally bulletproof, but:
- Check service records—oil changes every 15,000 miles or less are ideal
- Listen for unusual noises—especially from the top end or bottom end
- Verify no check engine lights—scan for codes even if the light isn’t on
- Transmission operation—Allison automatics should shift smoothly with no slipping
Brake System
HV trucks use air brakes with ABS . Check:
- Air dryer—recently serviced?
- Brake chamber condition—no rust or damage
- Pushrod stroke—within adjustment?
- ABS function—warning light should illuminate briefly then go out
Body and Mounting
If the truck has a dump body, water tank, or other equipment:
- Inspect the body mounts—stress cracks here indicate hard use
- Hydraulic system—check for leaks, proper operation, and fluid condition
- Electrical integration—aftermarket wiring can be a nightmare; look for professional installation
