History of the Kaiser Jeep M 715

Kaiser Jeep developed the M 715 as a response to the US Army's demand for a 1¼-ton military truck to replace aging Dodge M37s. Launched in 1967, the M 715 was based on the civilian Jeep Gladiator (J-series) pickup but reinforced for military use. Over 30,000 units rolled out from 1967 to 1969. The M 715 stood out for being one of the first US military tactical vehicles built from commercial truck components, marking a shift in procurement philosophy and setting a precedent for later COTS (Commercial-Off-The-Shelf) vehicles in military service. The M 715 was used in Vietnam, Korea, and various other theatres, earning a reputation for simplicity and ruggedness despite certain limitations.

Model History of the M 715 Series

The M 715 is part of the Kaiser Jeep M-series military trucks. Its design stemmed directly from the civilian Jeep Gladiator platform, but the M 715 gained heavy-duty axles, military-spec electrics, and a stripped-down utilitarian body. Its direct predecessor was the Dodge M37, a conventional military-only design, while successors include later military trucks like the Dodge M880 series. Alongside the M 715, variants such as the M 725 ambulance and M 726 telephone maintenance truck were produced on the same platform.

Unique Features and Statistics: Kaiser Jeep M 715

The M 715 distinguishes itself with a full steel bed, folding windshield, PTO-driven winch (optional), and a waterproofed 24-volt electrical system. The M 715’s straight-six engine was engineered for simplicity and field serviceability, and the cab's spartan interior was designed for durability over comfort. The vehicle is also notable for its switch from a dedicated military chassis to an adapted civilian platform, demonstrating engineering pragmatism.

Technical Data

Special Editions and Collectible Models

Several M 715 variants exist, including the M 724 (cab-chassis), M 725 (ambulance with modified body), and the M 726 (telephone maintenance configuration with a communications body). These variants are highly sought after due to their unique military fittings, limited production numbers, and surviving original configuration. Some vehicles have been modified post-service, so unmodified examples attract particular attention among collectors.

Weak Spots and Common Issues

No specific weak spots are currently documented from the supplied sources. However, field experience from enthusiasts commonly notes the 'Tornado' OHC engine’s sensitivity to poor maintenance, particularly oil change intervals and timing chain tension. The axles and leaf springs, while robust, require regular lubrication and inspection, especially after heavy off-road use. Body corrosion is observed in neglected vehicles due to limited underbody protection and exposure to the elements in military service. Electrical gremlins may arise due to aging 24-volt waterproof wiring and connectors.

Engine, Performance, Transmission, and Handling

The Kaiser Jeep M 715 is powered by a 3.8-litre inline-six Tornado OHC engine, which delivers moderate torque at low revs, supporting its off-road utility and towing capacity. Mated to a robust four-speed NP435 gearbox, it offers reliable drivetrain endurance typical for military trucks of its era. The part-time four-wheel drive and heavy-duty axles provide ample traction in off-road conditions; however, the vehicle’s tall centre of gravity, leaf-sprung suspension, and unassisted steering demand respect from the driver on rough terrain and at speed. Road handling is basic, with best results achieved at moderate speeds and on open ground. The original M 715 troop/cargo carrier is the most represented, but ambulances (M 725) and maintenance trucks (M 726) gain interest for their unique body configurations and potential for sympathetic restoration.

Interior, Comfort, Exterior and Design

The M 715’s exterior mirrors military priorities: a boxy, squat stance, flat fenders, and purpose-built cargo bed. The steel cab is minimalist, with exposed sheet metal and extremely basic instrumentation. Original paint was typically in Olive Drab, but some post-service vehicles show civilian or custom colours. Seating is limited to a simple bench covered in vinyl or canvas. Accessories such as a pioneer tool rack, blackout headlights, and a manual cab-operated windshield wiper system reflect its tactical role. Cab fit, finish, and materials are purely utilitarian, emphasizing durability and field reparability. Later civilian conversions may vary with added comfort features, but original army issue trucks are strictly functional inside and out.

Other Notable Features

The M 715 saw global service in allied militaries outside the US, occasionally in Latin American or Asian forces post-retirement. Spare parts availability is reliant on the Jeep Gladiator and classic truck community, with reproduction or NOS parts imported from the US. Its chassis is robust and can be subject to custom conversions, but originality is prized among collectors.

Summary

The Kaiser Jeep M 715 holds a specific niche as a postwar military truck that combined civilian engineering with battlefield requirements. Its spartan design, robust drivetrain, and relative rarity establish it as an attractive proposition for enthusiasts seeking utility, historical value, and a distinctly American classic military vehicle experience.
