• Fuel Efficiency Under Load: While a diesel truck might not get better empty MPG than a comparable gasoline truck, its efficiency under heavy loads significantly surpasses its gas counterparts. This translates to fewer stops at the pump and lower operating costs on long hauls.
• Strong Resale Value: Diesel trucks, especially well-maintained ones, tend to hold their value exceptionally well. Their demand in the used market ensures that your investment retains a good portion of its original worth.
• Advanced Technology and Comfort: The 2020 model year brought significant updates across the board for heavy-duty trucks. This includes more powerful engines, refined transmissions, sophisticated infotainment systems, advanced driver-assistance features, and often more comfortable and upscale interiors than previous generations.

Key Players: Top 2020 Diesel Truck Models

The 2020 heavy-duty diesel truck market was dominated by three major manufacturers, each offering formidable options.

• Ford F-Series Super Duty (6.7L Power Stroke V8 Turbo Diesel): Ford’s F-250, F-350, and F-450 Super Duty trucks are perennial best-sellers for a reason. For 2020, the 6.7L Power Stroke diesel received an upgrade, boosting its output to an impressive 475 horsepower and a class-leading 1,050 lb-ft of torque. Paired with a new 10-speed automatic transmission, these trucks offer exceptional towing prowess (up to 37,000 lbs for the F-450) and a comfortable, tech-rich cabin.



• Ram Heavy Duty (6.7L Cummins I6 Turbo Diesel): Ram’s 2500 and 3500 Heavy Duty trucks, updated for 2019, continued to impress in 2020. The legendary 6.7L Cummins inline-six diesel engine was available in two versions: a standard output (370 hp, 850 lb-ft) and a high-output variant (400 hp, 1,000 lb-ft), making Ram the first to hit the four-figure torque mark. Ram trucks are also celebrated for their coil-spring rear suspension (on 2500 models, offering a smoother ride) and their segment-leading luxurious interiors, especially in higher trims.
• Chevrolet Silverado HD / GMC Sierra HD (6.6L Duramax V8 Turbo Diesel): General Motors introduced an all-new Silverado and Sierra HD for 2020, featuring bold styling and an enhanced powertrain. The 6.6L Duramax V8 diesel was paired with an all-new 10-speed Allison automatic transmission, producing 445 horsepower and 910 lb-ft of torque.

What to Look For When Buying a Used 2020 Diesel Truck

Purchasing a used diesel truck requires a meticulous approach. Here’s a checklist of what to inspect:

• Maintenance Records: This is paramount for any diesel. Demand to see a complete service history. Look for regular oil changes (using diesel-specific oil), fuel filter replacements, DEF refills, and any reported repairs. A well-maintained diesel is a happy diesel.
• Engine Health:
  • Leaks: Check for oil, coolant, or fuel leaks around the engine bay and underneath the truck.
  • Unusual Noises: Listen for knocking, rattling, or excessive ticking.
  • Smoke: White smoke (coolant), blue smoke (oil), or excessive black smoke (fuel/turbo issues) are red flags. A little black smoke on hard acceleration is normal, but constant plumes are not.
  • Turbocharger: Listen for excessive whine or whistling, which could indicate turbo issues.
• Transmission Condition: Test all gears, both in drive and reverse. Look for smooth shifts without hesitation, jerking, or slipping.
• Frame and Body Inspection: Check for rust, especially on the frame, suspension components, and brake lines. Inspect for signs of accident damage (uneven panel gaps, mismatched paint).
• Tire Wear: Uneven tire wear can indicate alignment issues or suspension problems.
• Interior Condition and Features: Test all electronics, including the infotainment system, power windows, seats, and climate control. Check for excessive wear on seats, steering wheel, and pedals, which might not align with the reported mileage.
• Aftermarket Modifications: Be cautious of heavily modified trucks, especially those with performance tunes that may void warranties or stress powertrain components beyond their design limits. Ask for documentation for any modifications.
• VIN Check and Vehicle History Report: Always get a CarFax or AutoCheck report. This will reveal accident history, previous owners, reported mileage, service history, and any flood or salvage titles.

Important Considerations for 2020 Diesels

• Emissions Systems (DEF & DPF): 2020 diesels are equipped with Diesel Exhaust Fluid (DEF) systems and Diesel Particulate Filters (DPF) to meet stringent emissions standards. Understand that these systems require maintenance: DEF fluid needs regular refills, and the DPF undergoes "regeneration" cycles to burn off soot. Issues with these systems can be costly to repair.
• Fuel Type and Quality: Diesel engines require ultra-low sulfur diesel (ULSD). Using the wrong fuel or contaminated fuel can cause severe damage. Always refuel at reputable stations.
• Cost of Ownership: While fuel efficiency under load is a benefit, diesel trucks generally have higher maintenance costs than gasoline trucks. Parts can be more expensive, and specialized labor might be required. Factor this into your budget.
• Insurance Costs: Due to their higher value and repair costs, insurance premiums for diesel trucks can be higher.
• Towing Capacity vs. Your Needs: Don’t just buy the biggest truck. Match the truck’s towing and payload capacities to your actual needs. Over-specifying can lead to unnecessary costs.
• Trim Levels and Features: 2020 trucks offered a wide range of trim levels, from basic work trucks (XL, Tradesman, WT) to luxurious models (Platinum, Limited, Laramie Longhorn, Denali). Higher trims come with more features but also higher price tags. Decide which features are essential for you.

Tips for a Smooth Purchase

1. Set a Realistic Budget: Include not just the purchase price but also potential immediate maintenance, registration, insurance, and any accessories you plan to add.
2. Test Drive Thoroughly: Drive the truck on various road conditions. If possible, test drive it with a load similar to what you plan to haul. Pay attention to steering, braking, and suspension feel.
3. Get a Pre-Purchase Inspection (PPI): This is non-negotiable. Have an independent, certified diesel mechanic inspect the truck before purchase. They can identify potential issues that you might miss.
4. Negotiate Wisely: Research comparable listings in your area. Be prepared to walk away if the deal isn’t right.
5. Understand Financing Options: Explore financing through banks, credit unions, or the dealership. Compare interest rates and terms.
6. Check for Recalls: Use the VIN to check for any open safety recalls on the NHTSA website (nhtsa.gov). Ensure all recalls have been addressed.

Frequently Asked Questions (FAQ) about 2020 Diesel Trucks

Q: Are 2020 diesel trucks reliable?
A: Generally, yes. The 2020 models from Ford, Ram, and GM represent mature and refined diesel engine platforms. With proper maintenance, they are highly reliable and capable of long lifespans. However, like any complex machinery, individual reliability can vary, especially if maintenance has been neglected.

Q: What is DEF and how often do I need to refill it?
A: DEF (Diesel Exhaust Fluid) is a non-toxic solution injected into the exhaust stream to reduce nitrogen oxide emissions. Refill frequency depends on the truck model, tank size, and how you drive (towing uses more). Generally, you’ll need to refill it every 5,000 to 15,000 miles. Your truck will warn you well in advance when the DEF level is low.

Q: What’s the typical fuel economy for a 2020 diesel?
A: Fuel economy for heavy-duty diesel trucks is not rated by the EPA due to their weight class. However, in real-world driving, expect ranges from:

• Empty (highway): 18-24 MPG (2WD, depending on model/gearing)
• Mixed: 15-20 MPG
• Towing (heavy loads): 8-13 MPG
  The key benefit is that fuel economy doesn’t drop as drastically under load compared to gasoline trucks.

Q: Can I tow a fifth wheel with a 2020 2500/250 series truck?
A: Yes, absolutely! 2500/250-series trucks (e.g., F-250, Ram 2500, Silverado 2500HD) are specifically designed for towing large trailers, including most fifth wheels. Always check the specific truck’s payload and towing capacities (found on a sticker in the door jamb) against the loaded weight of your fifth wheel to ensure you’re within safe limits.

Q: What’s the difference between a 2500 and 3500 diesel truck?
A: The main difference lies in their payload and towing capacities.

• 2500/250-series (3/4-ton): Designed for heavy towing and hauling but typically has a lower Gross Vehicle Weight Rating (GVWR) and Gross Combined Weight Rating (GCWR) than a 3500. Often offers a slightly smoother ride (especially Ram 2500 with coil springs).
• 3500/350-series (1-ton): Built for maximum payload and towing, often featuring stronger suspension components (e.g., additional leaf springs), higher GVWR, and sometimes dual rear wheels (dually) for ultimate stability with very heavy loads.

Q: Are there common issues with 2020 diesels?
A: While generally reliable, like all vehicles, they can have specific quirks or potential issues. Common areas to monitor (not necessarily "issues" but maintenance points) include:

• Emissions System (DPF/DEF): Malfunctions in these systems due to poor maintenance or sensor failures can lead to "limp mode" and costly repairs.
• Fuel System: High-pressure fuel pumps and injectors can be sensitive to contaminated fuel.
• Turbocharger: Wear and tear can occur over high mileage.
• Electrical/Sensors: Modern trucks are packed with electronics, and sensor failures can sometimes trigger diagnostic codes.
  Most potential issues can be mitigated by strict adherence to the manufacturer’s maintenance schedule.
