### **Pros and Cons of Buying a 2013 2018 Dodge 2500/3500 Ram with a 6.7L Cummins Turbo Diesel (A2C90420000)**
#### **Pros**
1. **Reliability and Durability** The 6.7L Cummins is widely regarded as one of the most robust diesel engines ever produced. When properly maintained, it can easily exceed 500,000 miles with minimal issues. Many owners report smooth operation and strong torque output, making it ideal for heavy-duty towing and hauling.
2. **High Torque and Power** The Cummins produces **470 510 hp** and **850 975 lb-ft of torque**, depending on the model year and configuration. This makes it one of the most powerful diesel engines in its class, capable of effortlessly pulling heavy loads, trailers, or even performing off-road tasks.
3. **Strong Aftermarket Support** The Cummins has a vast aftermarket community, meaning parts, modifications, and upgrades are widely available. Tuning options (like Power Stroke, Haltech, or Cummins-specific ECU flashes) can further enhance performance and fuel efficiency.
4. **Fuel Efficiency (Compared to Gas Engines)** While not as efficient as modern diesel engines, the Cummins still offers **better MPG than equivalent gasoline V8s**, especially when properly maintained. In mixed driving, expect **8 12 MPG**, which is competitive for a heavy-duty truck.
5. **Resale Value** Cummins-powered Rams hold their value better than many other diesel trucks due to their reputation for longevity. A well-maintained 2013 2018 model can still fetch a decent price in the used market.
6. **Towing and Hauling Capability** The Ram 2500/3500 is rated for **up to 12,000 lbs of towing** (with proper equipment), making it one of the strongest trucks in its class. The Cummins torque ensures strong hill-climbing ability and stability under load.
7. **Off-Road and Heavy-Duty Performance** The Cummins low-end torque and strong build make it well-suited for off-roading, snow plowing, and other demanding applications. Many owners modify them with lift kits, exhaust systems, and cooling upgrades for extreme use.
8. **Lower Operating Costs (Long-Term)** Diesel fuel is often cheaper than gasoline per gallon, and with proper maintenance, Cummins engines require fewer repairs than gasoline V8s over time.

#### **Cons**
1. **High Initial Cost** New Cummins Rams were (and still are) expensive, and used models in good condition can still command a premium price. If you re on a tight budget, alternatives like the Ford Power Stroke or GM Duramax may be more affordable.
2. **Maintenance Requirements** While reliable, the Cummins is not a "set-and-forget" engine. It requires **regular oil changes (every 5,000 7,500 miles)**, **coolant flushes**, **fuel system maintenance**, and **air filter replacements** to prevent issues. Neglecting maintenance can lead to **injector failures, turbocharger problems, or cooling system failures**.
3. **Common Issues (If Neglected)**
- **Injector Failures** Older Cummins models (especially pre-2014) are prone to **fuel injector leaks or failures** if not serviced properly. Replacing injectors can cost **$2,000 $4,000 **.
- **Turbocharger Wear** The turbo is a high-stress component; failure can lead to **loss of power and expensive repairs**.
- **Cooling System Problems** The Cummins runs hot, and **radiator, water pump, and thermostat failures** are common if maintenance is skipped.
- **Transmission Issues** The **6-speed automatic (640R/660R)** can be finicky, especially in older models. Some owners report **rough shifting or failure** if fluid isn t changed regularly.
- **Exhaust Manifold Cracks** The cast-iron manifolds can crack over time, leading to **exhaust leaks and power loss**.
4. **Noise and Vibration** The Cummins is **loud** (especially at idle) and can have noticeable vibration at higher RPMs. Some owners find the noise level intrusive, though it s par for the course with a turbo diesel.
5. **Limited Modern Tech** Compared to newer trucks, the 2013 2018 Ram lacks **advanced driver aids (like adaptive cruise control, lane-keeping assist, or backup cameras)**. The infotainment system is also outdated by today s standards.
6. **Fuel Quality Sensitivity** Older Cummins engines can be **sensitive to poor-quality diesel fuel**, which may cause **filter clogs, injector issues, or DPF (Diesel Particulate Filter) problems** (though the 6.7L Cummins does not have a DPF in these years).
7. **Weight** The Ram 2500/3500 is **heavy**, which can affect fuel efficiency and handling, especially in city driving. The Cummins torque helps, but the truck still feels sluggish in stop-and-go traffic.
8. **Parts and Labor Costs** While parts are available, **labor costs for repairs can be high**, especially if you re not comfortable doing maintenance yourself. Some specialized Cummins-specific repairs (like injector work) require **highly skilled technicians**.

### **Conclusion**
The **2013 2018 Dodge Ram 2500/3500 with a 6.7L Cummins** is a **powerful, durable, and capable workhorse** that excels in towing, hauling, and heavy-duty applications. It is **one of the best diesel engines ever made**, provided it is **properly maintained**. However, it is **not a low-maintenance or quiet truck**, and **neglecting upkeep will lead to expensive repairs**.
If you **need a truck for extreme towing, off-roading, or commercial use** and can **commit to regular maintenance**, the Cummins Ram is an **excellent choice**. On the other hand, if you **prioritize comfort, modern tech, or lower upfront costs**, you may want to consider alternatives like:
- **Ford F-250/F-350 with Power Stroke 7.3L (pre-2011) or 6.7L (2011 )** Slightly cheaper, but the 7.3L is less refined.
- **Chevy Silverado 2500HD with Duramax 6.6L (2011 )** More modern tech, but slightly less torque than the Cummins.
- **Ram 2500/3500 with EcoDiesel (2014 )** If you want a newer Cummins with better emissions compliance.

### **Final Recommendation**
**Buy the 2013 2018 Cummins Ram if:**You **need maximum towing/hauling power** (12,000 lbs).
You **plan to maintain it properly** (oil changes, cooling system, injectors).
You **don t mind noise, vibration, and higher upfront costs** for a work truck.
You **want a proven, long-lasting engine** that can last **500,000 miles** with care.
**Avoid or reconsider if:**You **can t afford regular maintenance** (expect **$1,000 $2,000/year** for upkeep).
You **need a quiet, comfortable daily driver** (this is a **work truck**, not a family hauler).
You **want modern tech** (no advanced safety features, outdated infotainment).
You **don t have experience with diesel engines** (they require more knowledge than gasoline trucks).
**Best Approach:**- **Get a pre-purchase inspection (PPI)** from a **Cummins specialist** to check for **injector leaks, turbo health, and cooling system issues**.
- **Verify maintenance records** Look for **regular oil changes, fuel filter replacements, and cooling system flushes**.
- **Test drive under load** If possible, have the truck **tow a trailer or carry a heavy load** to ensure the engine and transmission perform well.
- **Budget for potential repairs** Even a well-maintained Cummins may need **injector replacements or turbo work** at some point.
**Final Verdict:** The **2013 2018 Cummins Ram is a fantastic work truck for the right buyer**, but it is **not a casual purchase**. If you re serious about owning one, **do your homework, maintain it religiously, and enjoy one of the most capable diesel trucks ever made**.
