The 2008 Mack GU713 is a vocational truck known for its ruggedness and versatility. Produced primarily for commercial use, this heavy-duty truck falls under the conventional cab category. While specific trim levels are less emphasized in vocational trucks compared to consumer vehicles, the GU713's popularity stems from its robust construction, powerful engine options, and adaptability for various demanding applications like construction, refuse, and heavy hauling. Its pricing range at the time of its production reflected its professional-grade capabilities.
The Good
The 2008 Mack GU713 excels in raw performance and unwavering reliability, built to conquer tough jobs. Its commanding presence appeals to pride, while its durable design and strong value proposition satisfy practical needs. This truck offers a solid, dependable workhorse for any demanding application.
The Bad
Potential weaknesses for the 2008 Mack GU713 often revolve around its age and the demanding nature of its work. Buyers should watch out for signs of extensive wear and tear, potential issues with aging electrical components, and the condition of the drivetrain and suspension due to heavy use.
2008 Mack GU713: Quick Overview
- Engine Options: The 2008 Mack GU713 was typically equipped with powerful diesel engines designed for heavy-duty work. Common options included Mack's own engines and potentially offerings from Cummins or other reputable manufacturers. Specific engine models varied based on customer configuration and intended application.
- Horsepower: Horsepower ratings generally ranged from approximately 300 hp to over 500 hp, depending on the chosen engine and its configuration. These engines were tuned for torque and pulling power rather than outright speed.
- Fuel Economy: Fuel economy is highly variable in vocational trucks like the GU713 and is heavily dependent on the engine, transmission, load, terrain, and driving style. Expect figures in the range of 5-8 miles per gallon (MPG) for highway driving under load, and significantly less in urban or heavy-duty operational cycles.
- 0-60 Times: 0-60 mph times are not a primary metric for this type of vehicle and are generally not published. These trucks are designed for sustained work and heavy loads, not rapid acceleration.
- Towing Capacity: The towing and hauling capacity of the 2008 Mack GU713 is substantial and configurable. It depends heavily on the specific chassis configuration, axle ratings, suspension, and fifth-wheel setup. These trucks are designed for Gross Combination Weight Ratings (GCWR) that can easily exceed 80,000 pounds, making them capable of towing heavy trailers and hauling immense loads.
- Trim-Level Features: As a vocational truck, the GU713 does not have traditional consumer-style trim levels. Instead, features are dictated by the specific vocational application it is built for. This includes chassis configurations (e.g., dump truck, tractor, mixer), suspension types, axle configurations, braking systems (air brakes are standard), and various body upfits. The cab interior might offer different levels of functionality and driver comfort, with options for air conditioning, power windows, and upgraded seating depending on the original order.

What Problems Does the 2008 Mack GU713 Have?
The 2008 Mack GU713, like many heavy-duty vocational trucks of its era, is built for demanding work, which can lead to specific types of issues over time. While specific model-year recalls for the 2008 GU713 are not prominently documented in a general consumer database, the overarching concerns for trucks of this age and type often include wear and tear on critical components.
Frequently reported problems tend to be related to the powertrain and chassis, especially if the truck has been subjected to rigorous use. This can include issues with the transmission (clutches, synchronizers, or electronic shifting components), the engine's cooling system (radiator leaks, fan clutch failures), and the exhaust system (DPF regeneration issues, especially if used for frequent short trips).
Suspension components, such as leaf springs, shocks, and bushings, can also experience accelerated wear due to heavy loads and rough terrain. Braking systems, particularly air brakes, require regular inspection and maintenance to ensure proper function and safety; seal leaks or air compressor issues can arise.
Electrical gremlins are also common in older trucks. This can manifest as intermittent sensor failures, issues with dashboard lights or gauges, problems with the HVAC system, or non-functional power accessories. The wiring harnesses, especially in exposed areas, can degrade over time due to vibration, heat, and moisture.
Long-term reliability for a 2008 Mack GU713 heavily depends on its maintenance history and the type of work it has performed. A well-maintained truck used for consistent, less abusive tasks will likely be far more reliable than one that has been operated at its maximum capacity in harsh environments with sporadic maintenance. It's crucial for potential buyers to seek out detailed service records and have a thorough pre-purchase inspection by a qualified heavy-duty mechanic.

How long will the 2008 Mack GU713 last?
The 2008 Mack GU713 is built for longevity, with many units expected to see service well over 500,000 miles or even surpass 1,000,000 miles with diligent maintenance. Owner data and typical maintenance habits suggest that these trucks can endure for 15-20 years or more.
Its long-term durability is a hallmark, thanks to robust Mack-engineered components and heavy-duty construction. Weaknesses that can emerge over time are primarily due to the sheer volume of work and environmental exposure: powertrain components can wear down, suspension parts require replacement, and electrical systems may become less reliable. However, with a commitment to regular servicing, proactive repairs, and addressing minor issues before they escalate, the GU713 remains a remarkably enduring workhorse.

What Technology & Safety Features are Included?
The 2008 Mack GU713, being a dedicated vocational truck, prioritizes function and safety over advanced tech and entertainment found in consumer vehicles. Built-in technology is generally utilitarian. The dashboard typically features essential analog gauges for engine monitoring (RPM, oil pressure, coolant temperature, air pressure), speedometer, and fuel level. Basic diagnostic indicators are present.
Entertainment systems are usually limited to a standard AM/FM radio, and potentially an optional CD player. Connectivity features like Bluetooth or USB ports are unlikely to be standard and would have been rare optional additions for that model year. The focus is on operational information rather than infotainment.
Driver-assistance features as we know them today are largely absent. The primary safety aids are robust braking systems, typically air brakes with ABS (Anti-lock Braking System) as a standard or common option, which are critical for controlling heavy loads. Visibility from the conventional cab is generally good, aiding in situational awareness.
Safety features are centered around the truck's structural integrity and mechanical systems. The durable chassis and cab construction are designed to protect occupants in the event of an impact. Standard safety equipment would include seat belts, and depending on the configuration, perhaps advanced lighting systems.
Official crash-test ratings from organizations like the NHTSA or IIHS are generally not applicable or available for heavy-duty vocational trucks like the 2008 Mack GU713, as they are not classified or tested under the same frameworks as passenger cars or light-duty trucks. Their safety is assessed based on their operational performance, braking capabilities, and the inherent robustness of their construction to withstand the stresses of commercial use.

2008 Mack GU713 Prices and Market Value
When new, the 2008 Mack GU713 would have commanded a significant price, typically ranging from around $80,000 to over $150,000, depending heavily on its specific configuration, engine choice, and vocational upfits.
Current used market prices for a 2008 Mack GU713 vary widely, generally falling between $15,000 and $50,000, with older, higher-mileage, or heavily used units at the lower end. Well-maintained trucks with desirable configurations can fetch higher prices.
Depreciation on vocational trucks is less predictable than on consumer vehicles. While they lose value, their inherent utility and robust construction mean they retain a significant portion of their value for longer, especially if they are in good working order. Factors affecting resale value include mileage, overall condition, maintenance history, specific vocational equipment (e.g., dump body, crane), tire condition, and engine/transmission health.
