Review OSHKOSH Military 8x8 Hemtt By Full Overhaul In Runs Great

The **Oshkosh M985A1 8x8 High Mobility Multipurpose Wheeled Vehicle (HMMWV)**, commonly referred to as the "Humvee," is a legendary military engineering marvel that has served as the backbone of American and allied ground mobility since its introduction in the late 1980s. Originally developed by Oshkosh Truck Corporation under the **M985A1** designation in the late 1980s, this 8x8 configuration was later refined and produced in updated variants, including the **2006-era models**, which incorporated advanced engineering, enhanced durability, and improved tactical capabilities. Designed to replace the aging M151 MUTT (Multi-purpose Utility Truck) and M35 2 -ton truck, the M985A1 was engineered to excel in extreme environments, offering superior off-road performance, high-speed mobility, and unmatched versatility for both troop transport and cargo hauling. Standing on a robust **8x8 wheelbase**, this vehicle features a **V8 diesel engine** paired with an advanced automatic transmission, delivering a powerful **300-350 horsepower output** that propels it through rugged terrain with ease. Its **high-ground-clearance suspension system**, reinforced chassis, and **all-terrain tires** allow it to traverse deep sand, mud, and rocky surfaces while maintaining stability at highway speeds. The **2006-era models** incorporated significant upgrades, including **enhanced armor protection**, improved fuel efficiency, and refined ergonomic interiors to accommodate troops or specialized equipment. The M985A1 s **modular design** allows for quick reconfiguration, enabling it to serve as a command vehicle, ambulance, artillery tractor, or even a mobile repair platform, making it indispensable in both combat and humanitarian missions. With a **payload capacity exceeding 10,000 pounds**, it can transport troops, heavy weapons, or critical supplies with ease, while its **ballistic-resistant cab** and **mine-resistant undercarriage** provide critical protection against small arms fire and improvised explosive devices. Over its decades of service, the M985A1 has proven itself in conflicts from the **Gulf War to Iraq and Afghanistan**, earning a reputation as one of the most reliable and adaptable military vehicles in history. Whether deployed in deserts, jungles, or urban environments, this **8x8 HEMTT (Heavy Expanded Mobility Tactical Truck)** remains a symbol of American engineering resilience, embodying the perfect blend of power, durability, and tactical ingenuity.

### **Pros and Cons of Buying a 1989 M985A1 (8x8 HEMTT) with a 2006 Oshkosh Upgrade**

#### **Pros**

1. **Military Proven Reliability** The M985A1 is a well-established, battle-tested vehicle designed for heavy-duty transport. Its 8x8 configuration provides superior off-road capability, making it suitable for rugged environments.

2. **High Payload Capacity** The M985A1 is built to carry heavy loads, including troops, equipment, and supplies. The 2006 Oshkosh upgrade likely improved suspension and chassis strength, enhancing its load-bearing capacity.

3. **Durability and Longevity** Military vehicles are built to last decades with proper maintenance. The M985A1, even from 1989, can still be operational if well-preserved, especially with the Oshkosh modifications.

4. **Off-Road Performance** The 8x8 configuration ensures excellent traction and stability on uneven terrain, making it ideal for construction, disaster response, or remote operations.

5. **Customizable and Upgradable** The Oshkosh upgrade suggests modifications that may include improved suspension, better fuel efficiency, or enhanced protection, increasing its versatility.

6. **Resale Value in Niche Markets** While not a common civilian vehicle, military surplus trucks like this can still find buyers in specialized industries (e.g., government contractors, heavy hauling, or off-road enthusiasts).

7. **Potential Cost Savings** Purchasing a used military vehicle can be cheaper than buying a new heavy-duty truck, especially if the Oshkosh upgrade has already been done.

#### **Cons**

1. **High Maintenance Requirements** Military vehicles are complex and require specialized knowledge for repairs. Parts may be expensive or difficult to source, especially for older models.

2. **Age-Related Wear and Tear** A 1989 chassis, even with upgrades, may have degraded components like suspension, drivetrain, and electrical systems. The Oshkosh modifications may not fully compensate for decades of use.

3. **Fuel Inefficiency** Older military trucks are not optimized for fuel economy. The M985A1 likely consumes more diesel than modern heavy-duty trucks, increasing operational costs.

4. **Limited Civilian Availability of Parts** While Oshkosh produces commercial vehicles, military-specific components (e.g., certain suspension parts, military-grade tires) may not be readily available off-the-shelf.

5. **Regulatory and Compliance Issues** Depending on jurisdiction, military surplus vehicles may require special permits for road use, inspections, or modifications to meet civilian safety standards.

6. **Potential Hidden Damage** Without a thorough inspection, the vehicle could have undocumented structural damage, rust, or mechanical failures that reduce its lifespan or safety.

7. **Resale Challenges** Unlike commercial trucks, the M985A1 has a very niche market. Selling it later may be difficult unless you have a specific buyer in mind.

### **Conclusion**

Buying a 1989 M985A1 with a 2006 Oshkosh upgrade can be a smart investment if you need a **heavily built, off-road-capable truck** for specialized work (e.g., military contractors, disaster relief, or heavy hauling). The Oshkosh modifications likely improve its usability, but the age of the chassis remains a significant factor.

- Have access to **specialized mechanics** familiar with military vehicles,

- Can **afford high maintenance costs**,

- Need **unmatched off-road capability**,

- Are willing to **deal with regulatory hurdles,**

- Have a **clear use case** (not just general transport),

then this could be a worthwhile purchase.

- Are looking for a **lower-maintenance, fuel-efficient truck**,

- Need **easy parts availability and resale flexibility,**

- Plan to use it for **standard road transport,**

- Lack **expertise in military vehicle upkeep,**

then a newer commercial 8x8 truck (e.g., Oshkosh Defense or a heavy-duty Freightliner) may be a better long-term choice.

### **Recommendation**

- **Get a full mechanical inspection** by a specialist familiar with military vehicles.

- **Verify the extent of the 2006 Oshkosh upgrades** ensure critical components (suspension, drivetrain, fuel system) are in good condition.

- **Budget for maintenance** expect higher costs than a commercial truck.

- **Check local regulations** some states require special permits for military surplus vehicles.

- **Consider a used but newer model** (e.g., M985A2 or a modern Oshkosh 8x8) if available, as they may offer better reliability and parts support.

For most civilian buyers, a **newer, commercially available 8x8 truck** would be a safer and more practical choice. However, if you have a **specific need for a military-grade vehicle**, the M985A1 with Oshkosh upgrades could still be a valuable asset with proper care.

Bought this spare cab from Ft. Would need an RGN disconnect flat bed for removal. It will come with 2 new spare tires and LVSR cab. One side panel on the rear cargo bed has a dent in it, otherwise everything is great.

In personal collection for last 10 years and maintained since then. Runs and drives perfect, starts great every time. Really exciting to dive. Hood as spare parts in case I needed it, but never used anything.

Has 4,162 miles with 3,022 operating hours. length 401, height : 110, width : 96 Ground Clearance:24 Has 450HP Detroit Diesel V-8 engine with Allison transmission.
