For American truck owners, durability is a badge of honor and nothing screams longevity like a diesel pickup that can cross the 300,000-mile mark.
Diesel trucks offer unmatched torque, impressive fuel economy, and a reputation for longevity that gasoline counterparts rarely match.
Whether you’re towing a fifth-wheel RV, running a construction business, or just need a rock-solid workhorse, these used diesel pickups have proven they can go the distance sometimes even doubling that 300,000-mile milestone with proper maintenance.
Below are ten of the best used diesel trucks that are known to exceed 300,000 miles, making them ideal long-haul companions for American buyers.
1. Ford F-250/F-350 Super Duty (6.7L Power Stroke V8)
Introduced in 2011, the 6.7L Power Stroke V8 diesel engine turned the tide for Ford’s Super Duty lineup. This engine, built in-house by Ford, delivers powerful torque for towing and hauling without sacrificing reliability.
With regular oil changes and proper maintenance, these trucks especially models from 2015 onward can easily exceed 300,000 miles.
The F-250 and F-350 are staples among contractors and farmers alike due to their rugged build and towing capability.
The 2025 Ford F-250 Super Duty stands out as a top-tier heavy-duty pickup, offering a spacious and comfortable cabin, exceptional towing and hauling capacities, and a host of advanced technologies designed to assist with heavy-duty tasks.
Four-wheel drive comes standard on most trims, enhancing its off-road and load-handling performance. However, the truck’s price can escalate quickly with optional features, and its tall ride height can make entry challenging without side steps.
New for 2025, the range-topping Limited trim has been replaced by the Platinum Plus package, offering even more luxury and capability.
Additionally, more available options have been introduced to further simplify towing, and the updated Ford Pro Vehicle Integration System 2.0 now streamlines the installation of aftermarket accessories. The 2025 model continues as part of the fourth-generation F-Series Super Duty lineup, which was first introduced in 2023.
If the F-150’s towing and payload capacities aren’t sufficient for your needs or if you specifically want the Power Stroke diesel then upgrading to the F-250 Super Duty is a smart move.
Sitting just below the more robust F-350, which offers a dual-rear-wheel (DRW or dually) setup, the F-250 delivers plenty of strength for the majority of truck owners. Its lineup of four powerful engines provides class-leading performance, and it includes a long list of practical towing and hauling technologies.
Features such as the newly optional blind-spot monitoring system with trailer coverage and a trailer tire-pressure monitoring system add an extra layer of safety and convenience. Trim options range from the no-nonsense XL to the luxurious Platinum, giving buyers flexibility in terms of price and features.
Monthly driving costs for the F-250 Super Duty XL are estimated at $231 per month based on data from North Dakota, though EPA fuel economy testing has not been performed for this trim. Compared to the average large truck, the F-250 holds its own in terms of projected cost of ownership.
As for towing, the F-250 is a true champion. Its maximum conventional towing capacity reaches 22,000 pounds in certain configurations when paired with either version of the Power Stroke diesel engine.
Fifth-wheel and gooseneck towing capacities go even higher, up to 22,300 and 23,000 pounds, respectively, when using the regular cab model.
Altogether, these additions make the 2025 F-250 Super Duty not just a workhorse but a highly intelligent and user-friendly one.
2. Ram 2500/3500 (6.7L Cummins I6)
The Ram Heavy Duty trucks powered by the 6.7L Cummins inline-six diesel engine are legendary for their bulletproof performance.
This engine is a favorite in the diesel community due to its simplicity and durability.
Rams equipped with the Cummins diesel often last well beyond 300,000 miles, especially the ones paired with a manual transmission (pre-2018) or the beefy Aisin automatic transmission.
They’re known for towing heavy loads with confidence while staying relatively easy to service.
The Ram pickup earned widespread praise with last year’s redesign, and the 2011 Ram 2500 carries forward several standout features that maintain its strong presence in the fiercely competitive heavy-duty truck segment.
Its significantly improved cabin showcases an attractive layout paired with high-quality materials, positioning the Ram as the segment leader in interior design.
Ride quality is another strength, with a relatively compliant suspension setup, hydraulic cab-to-frame mounts, and minimal intrusion from road and wind noise, all contributing to a commendably comfortable driving experience.
When it comes to the Ram 2500’s work capabilities, it’s easy to see why these trucks are referred to as “heavy duty.”
When properly configured, the truck boasts a maximum towing capacity exceeding 15,000 pounds, depending on the chosen body style and powertrain, while its top hauling capacity reaches 3,120 pounds. The base engine, a 5.7-liter V8, delivers 383 horsepower and 400 pound-feet of torque.
However, to truly harness the truck’s heavy-duty potential, the diesel powertrain is the better option. The 6.7-liter Cummins turbodiesel inline-six engine generates 350 horsepower and 650 pound-feet of torque in early model year variants.
Notably, that torque figure climbs to 800 pound-feet when the engine is paired with an automatic transmission. This increase plays a crucial role in helping the Ram stay competitive against heavyweights from GM and Ford.
When stacked up against its limited pool of direct competitors, the 2011 Ram 2500 holds its own in what is essentially a neck-and-neck race with the 2011 Ford F-250 and 2011 Chevy Silverado 2500HD.
Still, few would likely argue with the claim that the Ram boasts the most visually appealing design and a surprisingly refined and upscale interior.

3. Chevrolet Silverado 2500HD/3500HD (6.6L Duramax LBZ or LMM)
The Duramax diesel engine, especially the LBZ (2006–2007) and LMM (2007.5–2010) variants, made GM trucks highly sought-after on the used market.
These engines are known for their long life, smooth performance, and ability to tow or haul without breaking a sweat.
Owners often report passing 300,000 miles with little more than regular oil changes, fuel filter swaps, and careful attention to injector health. These trucks strike a nice balance between comfort and rugged capability.
Since its debut in 2020, this generation of the Chevrolet Silverado HD has consistently proven itself to be a very capable truck, though it was never known for being the most stylish or refined. However, the 2024 update directly addresses those weak points, and the result is a truck that now comes impressively close to perfection.
The Silverado 2500HD retains its signature bold, boxy, and brash aesthetic, but the design now feels more cohesive compared to the previous iteration. Inside, the transformation is even more striking.
The formerly dull and uninspired cabin has been replaced with a modern, upscale interior that emphasizes user-friendliness and high-tech functionality, marking a significant step forward in both comfort and appeal.
Driving the Silverado 2500HD, whether with an empty bed or while towing a heavy load, highlights one of the truck’s strongest attributes, its refined on-road manners.
It remains composed and comfortable in a variety of conditions, and when outfitted with the Duramax diesel engine, it also delivers impressive speed and responsiveness. That said, a firmer brake pedal would enhance driver confidence, especially when trying to bring this more-than-four-ton machine to a stop.
Despite the many improvements, there are still a few elements holding the Silverado 2500HD back from being the ultimate heavy-duty truck. The standard gasoline engine, while now paired with a 10-speed automatic transmission that improves performance, still lags behind the turbodiesel in terms of capability.
It’s also worth noting that certain upscale features, such as massaging seats and a premium audio system—are available in the Silverado 1500 but curiously absent from the 2500HD.
In terms of towing aids, some competing heavy-duty trucks offer more practical and innovative options. Perhaps the most significant drawback is that base trim levels of the Silverado 2500HD continue to use the outdated interior design, which undermines the overall lineup.
However, if you’re able to opt for one of the higher-end trims, you’ll find yourself behind the wheel of a truly exceptional truck.
4. Ford F-250/F-350 Super Duty (7.3L Power Stroke V8)
The 7.3L Power Stroke V8 (1994–2003) is arguably the most iconic diesel engine Ford has ever built. Though not the most powerful by modern standards, it’s revered for its simplicity, mechanical robustness, and ease of maintenance.
These trucks regularly clock 300,000 miles or more and are still highly valued on the used market. Enthusiasts often call the 7.3L Power Stroke “million-mile capable” when properly maintained.
The 2025 Ford F-250 Super Duty is a well-rounded heavy-duty pickup that brings plenty to the table. It boasts a spacious and comfortable cabin, excellent towing and hauling figures, and a wide array of available technologies designed to make those demanding tasks easier.
Most trims come standard with four-wheel drive, enhancing its capability across various driving conditions. However, there are a couple of trade-offs. The price can escalate quickly with added options, and its tall ride height may make entry challenging without side steps.
For 2025, there are several notable updates. The range-topping Limited trim has been replaced by the new Platinum Plus package.
Additional towing-friendly options have been introduced, and Ford’s Pro Vehicle Integration System 2.0 has been implemented to make aftermarket-accessory installation easier. This model remains part of the fourth-generation F-Series Super Duty lineup, which was launched in 2023.
According to automotive expert Michael Cantu, “If the F-150’s towing and payload capacities aren’t enough for your needs or if you want that Power Stroke diesel, then consider upgrading to the 2025 F-250 Super Duty.”
Positioned just below the more robust F-350, which features a dual-rear-wheel (DRW or dually) configuration, the F-250 delivers more than enough capability for the majority of truck owners. It offers a lineup of four powerful engines, each contributing to class-leading performance.
A wealth of practical towing and hauling technologies further enhances its appeal, including newly available blind-spot monitors with trailer coverage and a trailer tire-pressure monitoring system. Buyers can choose from a wide range of trims, starting with the no-frills XL and going up to the premium Platinum model.
In terms of cost to drive, monthly estimates for the F-250 Super Duty XL are approximately $231 based on figures from North Dakota, though this trim has not been tested by the EPA for fuel economy. When compared to the average large truck, the F-250 remains competitive in ownership costs.
Edmunds highlights the F-250 as “A towing champ.” Its maximum conventional towing capacity reaches up to 22,000 pounds in select configurations when equipped with either version of the Power Stroke diesel engine.
For fifth-wheel and gooseneck towing, the regular cab model delivers up to 22,300 and 23,000 pounds respectively, while SuperCab and crew-cab variants offer slightly lower capacities. These figures comfortably cover the needs of most people towing trailers or boats.
The F-250 also includes advanced features like Onboard Scales with Smart Hitch, which estimates cargo and trailer tongue weight; Pro Trailer Hitch Assist, which guides the truck into position for hitching automatically; and Turn Signal View, which activates a side-view camera when the turn signal is engaged. Altogether, these additions solidify the 2025 F-250 Super Duty’s position as a top choice in the heavy-duty truck segment.

5. Ram 3500 Dually (5.9L Cummins 12-valve or 24-valve)
Before emissions equipment became more complex, the 5.9L Cummins was a simple, nearly indestructible inline-six diesel engine.
The 12-valve (1989–1998) and early 24-valve (1998.5–2002) versions are known for surviving high mileage, often over 400,000 miles.
The dually configuration is a favorite for heavy-duty towing and commercial applications. With minimal electronics, these engines are easy to work on and cheap to maintain perfect for a reliable, used diesel pickup.
6. Chevrolet Silverado 2500HD (6.6L Duramax LLY or LBZ)
Among diesel aficionados, the LLY (2004.5–2006) and LBZ (2006–2007) engines stand out as some of the best versions of the Duramax line.
These engines lack the complicated emissions systems of newer diesels and are capable of reaching 300,000 miles or more with regular maintenance.
The Allison transmission paired with these engines adds to the appeal, making them excellent choices for long-term reliability and performance.
7. GMC Sierra 2500HD/3500HD (6.6L Duramax Diesel)
Closely related to the Silverado, the GMC Sierra HD models offer the same engine choices and robust capability but with a slightly more upscale interior.
Diesel versions from the early to mid-2000s, especially those with the LBZ engine, have built reputations for crossing the 300,000-mile threshold without major mechanical failure.
These trucks are also relatively affordable on the used market compared to newer models. Think of the GMC Sierra HD pickup as the brawnier sibling of the near-ubiquitous Sierra 1500 half-ton.
With stronger bones and upgraded running gear, the Sierra 2500HD and 3500HD outperform the 1500 in towing and hauling and take pride in their heavy-duty capabilities.
But working hard doesn’t mean sacrificing comfort, as the Sierra HD lineup can be configured to be either utilitarian or luxurious, depending on your needs.
The available Denali and Denali Ultimate trims introduce high-end comforts and conveniences that were once exclusive to luxury sedans, giving the Sierra HD an advantage over its sibling, the Chevy Silverado HD, which isn’t quite as plush.
8. Ford Excursion (7.3L Power Stroke Diesel)
Though technically an SUV, the Ford Excursion with the 7.3L Power Stroke diesel deserves mention. Built on the Super Duty platform, the Excursion diesel offers massive interior space with the durability of a work truck.
Many Excursions still on the road today have surpassed 300,000 miles, making them beloved by large families, overlanders, and towing enthusiasts alike.
The Excursion was Ford’s answer to the ninth-generation Chevrolet Suburban, but a myriad of issues prevented it from gaining popularity.
The situation worsened to the point where production, which began in 1999, ended just a few years later in 2005. Ironically, the Excursion was poised to be a major seller for Ford, with dealers ordering more than half the number of vehicles the company anticipated moving in its first year.
That positive outlook quickly unraveled when environmental groups set their sights on the 19-foot-long, nearly 8,000-pound SUV even before its launch.
The Sierra Club went so far as to run a contest on its website to rename the vehicle — the winner was the Ford Valdez, a nod to the oil tanker that caused an environmental disaster in Alaska. And they weren’t wrong.
According to the Sierra Club, the Excursion would “emit more than quintuple the amount of carbon compared to a normal car.”
9. Nissan Titan XD (5.0L Cummins V8 Diesel)
The Titan XD bridged the gap between light-duty and heavy-duty pickups, and its short-lived 5.0L Cummins V8 (available from 2016–2019) provides decent towing capability with diesel efficiency.
While not as proven as the Power Stroke or traditional Cummins inline-six engines, many well-maintained Titan XDs have proven capable of long lifespans, with several owners reporting mileage beyond 250,000 and climbing.
Its lighter towing loads and less intense use may even help it hit the 300K milestone under the right conditions.
The Titan XD qualifies as a heavy-duty pickup primarily because its Gross Vehicle Weight Rating (GVWR) exceeds 8,500 pounds, a feat made possible by its use of robust components previously developed and tested in Nissan’s NV line of commercial vans.
For its XD application, the fully boxed ladder frame was not only modified but also extended to a 151.6-inch wheelbase, allowing it to support the standard crew-cab configuration and a 6.5-foot bed.
Interestingly, heavy-duty trucks are legally required to have a bed that is at least 6 feet in length, which explains why the XD does not come with a shorter bed option like many regular-duty crew cabs.
While this longer bed improves versatility, it also results in a vehicle that’s roughly as unwieldy as a typical 2500-series crew cab, stretching over 20 feet in total length.
Under the hood, the standard engine is a significantly revised and modernized version of Nissan’s 5.6-liter gasoline V8, now generating 390 horsepower and 401 lb-ft of torque. However, the standout option for the XD is the all-new Cummins 5.0-liter V8 diesel engine, delivering 310 hp and an impressive 555 lb-ft of torque
While this output doesn’t quite reach the levels achieved by the heavy-duty diesel engines from Chevrolet, Ford, and Ram, it far surpasses the Ram 1500’s diesel V6, which produces 240 hp and 420 lb-ft.
When looking at towing numbers, the Ram 1500 diesel tops out at 8,870 pounds in crew cab configuration, whereas 2500-series HD diesel trucks typically tow between 14,000 and 17,000 pounds. The Titan XD diesel finds a sweet spot in between, with a maximum towing capacity of 12,314 pounds which might be more than adequate for most needs.
That said, it could also be more than necessary, in which case the upcoming 2017 regular-duty Nissan Titan might be a better option.
This half-ton variant will differ slightly in appearance, particularly at the front end — due to the absence of the large diesel V8 and will offer a 5.5-foot short bed. Otherwise, it will share a very similar interior and overall design with the XD. When it comes to direct rivals, the only other regular-duty truck with diesel power remains the aforementioned Ram 1500 EcoDiesel.
Meanwhile, on the heavy-duty end, the recently updated Chevrolet Silverado 2500HD, as well as the trusted Ram 2500 and Ford F-250, all provide high-output diesel options. But if you’re looking for something in the middle ground, the 2016 Nissan Titan XD should definitely be on your test-drive list.
10. International Harvester/Navistar Scout and Pickups (IDI Diesel)
Though more of a vintage entry, older diesel pickups from International Harvester and Ford’s early IDI diesel trucks (before the Power Stroke era) were built with longevity in mind.
These trucks featured simple mechanical diesels that were slow but incredibly durable.
While hard to find today, enthusiasts often restore them and rack up hundreds of thousands of miles thanks to their tank-like construction and rebuildable engines.
Used diesel pickups aren’t just about brute strength they’re also about long-term value. With the right model, proper maintenance, and a little care, many of these trucks can easily pass the 300,000-mile mark.
Whether you’re shopping for a farm workhorse, a reliable tow rig, or just want a dependable daily driver with serious capability, these diesel trucks have proven they’re in it for the long haul.
When buying used, always check service records, inspect for rust and frame integrity, and have the truck thoroughly evaluated by a diesel mechanic.
A well-kept diesel truck may outlast even two or three newer gas trucks, saving you money and headaches over the years.
