Best Ram 3500 Model Years (Ranked) in 2027

1. 2019-2024 Ram 3500 HO Cummins

The 2019-2024 fifth-generation DT Ram 3500 with the high-output 6.7L Cummins ranks first because it delivers the most capability and refinement in the lineup. It produces 400 horsepower and 1,075 lb-ft of torque, paired exclusively with the heavy-duty Aisin AS69RC six-speed automatic. Properly equipped gooseneck ratings reach roughly 37,000 pounds, and fifth-wheel figures land in the 30,000-35,000-pound range.

This truck is for buyers who need maximum towing capacity daily and can absorb the higher purchase price and depreciation exposure. It trades away the lower entry cost of older models for superior ride quality, cabin tech, and reduced downtime risk. Compared to the 2013-2018 DS below, it costs roughly $8,000 more but offers a documented maintenance history and zero unplanned downtime in typical two-year ownership.

2. 2013-2018 Ram 3500 Cummins

The 2013-2018 fourth-generation DS Ram 3500 with the 6.7L Cummins ranks second as the best value pick, offering near-current capability at a steep discount to fifth-gen money. The 6.7L reached full maturity here, with torque climbing toward 900 lb-ft on Aisin-equipped High Output trucks. Rear air suspension became available for self-leveling under load, and the cabin still holds up well.

This truck is for buyers who need heavy towing but prioritize purchase price over the latest tech. It trades away the refined interior and updated frame of the 2019-2024 DT, but keeps the same Cummins durability. The critical condition is documented fuel-system history—the Bosch CP4.2 pump can fail and send metal through the entire system, a five-figure repair.

3. 2019-2024 Ram 3500 6.4L Hemi

The 2019-2024 DT Ram 3500 with the 6.4L Hemi gas engine ranks third because it eliminates the diesel-specific risks entirely while offering a stout 410 horsepower and 429 lb-ft of torque. It pairs with an eight-speed automatic, and there is no CP4 pump, no DEF, and no diesel particulate filter to fail. The entry price is significantly lower than the Cummins, and the maintenance profile is dramatically simpler.

This truck is for buyers who tow occasionally or moderately and want modern comfort without diesel upkeep costs. It trades away the Cummins' torque, towing capacity, and fuel economy—gooseneck ratings are lower, and it has shorter legs on grades. Compared to the 2019-2024 HO Cummins above, it costs less upfront and avoids the five-figure fuel-system tail risk. For an RV owner or light contractor, this is the smarter financial choice despite lower headline numbers.

4. 2013-2018 Ram 3500 6.4L Hemi

The 2013-2018 DS Ram 3500 with the 6.4L Hemi gas engine ranks fourth because it offers the same stout 410 horsepower and 429 lb-ft as the newer gas model but at a much lower used price. It pairs with a six-speed automatic, and these trucks are plentiful and inexpensive on the used market. A clean 2015-2018 example in single-rear-wheel or dually form is a low-stress purchase with no CP4, DEF, or DPF concerns.

This truck is for contractors or RV owners who tow occasionally and want a heavy-duty chassis without diesel complexity. It trades away the modern interior, eight-speed transmission, and updated frame of the 2019-2024 DT gas truck above. The older six-speed is less refined, and the ride is harsher, but the purchase price is substantially lower.

5. 2010-2012 Ram 3500 6.7L Cummins

The 2010-2012 early DS Ram 3500 with the 6.7L Cummins ranks fifth because it delivers solid diesel capability—up to 350 horsepower and 800 lb-ft in High Output trim—at a price well below 2013-up trucks. The cabin is more refined and the ride is better than the third-generation models. However, these trucks are aging now, so buyers must confirm the DPF and EGR systems are present and functioning, and the fuel system is healthy.

This truck is for buyers who need diesel towing power but cannot stretch to a 2013-2018 model. It trades away the higher torque output (900 lb-ft) and rear air suspension of the 2013-2018 DS above. The early DS also carries the CP4.2 pump risk, so documentation is essential. Compared to the 2013-2018 Cummins, it is cheaper but older, with more potential for emissions-related repairs and front-end wear.

6. 2007.5-2009 Ram 3500 6.7L Cummins

The 2007.5-2009 third-generation Ram 3500 with the 6.7L Cummins ranks sixth because it offers roughly 350 horsepower and 650 lb-ft of torque, a step up in displacement from the 5.9L. The bigger engine lifted capability, but the early diesel particulate filter and regeneration system can clog on trucks used for short trips. Favor examples with documented highway duty and an intact, unmolested exhaust system.

This truck is for buyers who want a 6.7L Cummins at a lower price than a fourth-generation model, accepting the risk of DPF issues. It trades away the refined cabin and higher torque of the 2010-2012 DS above. The early 6.7L is less mature, and the regeneration system is problematic for short-trip use. Compared to the 2003-2007 5.9L below, it has more power but more complexity and maintenance.

7. 2003-2007 Ram 3500 5.9L Cummins

The 2003-2007 third-generation Ram 3500 with the 5.9L Cummins common-rail ranks seventh because it is the lowest-maintenance diesel in the entire lineup—no DPF, no DEF, and no CP4 pump, using the bulletproof Bosch CP3 instead. It makes roughly 305-350 horsepower and up to 650 lb-ft late in the run, which is still plenty for heavy towing. This engine is a cult object for good reason: mechanical simplicity and legendary durability.

This truck is for buyers who value simplicity and are willing to work on an older vehicle, or who want a dedicated tow rig without emissions complexity. It trades away the power and modern cabin of the 2007.5-2009 6.7L above. The 5.9L is less capable but far easier to maintain and repair. Compared to newer trucks, it lacks the torque and towing electronics, but it avoids the five-figure fuel-system and emissions failures.

8. 2003-2009 Ram 3500 5.7L Hemi V10

The 2003-2009 third-generation Ram 3500 with the 5.7L Hemi or V10 gas engine ranks eighth because it is cheap to buy but thirsty and gives up capability and resale value to the diesel trucks. The 5.7L Hemi makes 345 horsepower and 375 lb-ft of torque, which is adequate for light one-ton duty but not for heavy gooseneck work. The V10 is even less common and more fuel-hungry.

This truck is for buyers who need a heavy-duty chassis for light tasks—like hauling a service body or a small trailer—without diesel costs. It trades away the towing capacity and engine braking of the 5.9L Cummins above. The gas engine is simpler and cheaper to maintain, but fuel economy is poor and resale is weak. Compared to the 2013-2018 6.4L Hemi, it is significantly older and less refined.

9. 2019-2020 Ram 3500 Early DT

The 2019-2020 early-build fifth-generation DT Ram 3500 ranks ninth because, while the mechanicals are excellent, these first-run trucks carry normal redesign risk. Some early owners reported infotainment glitches, minor electrical bugs, and fit-and-finish quirks as the new platform settled. The high-output Cummins and Aisin transmission are identical to later models, so the core is sound. The caution is about the details, not the drivetrain.

This truck is for buyers who want the 2019-2024 DT benefits but are shopping used and may find a lower price on an early example. It trades away the peace of mind of a later, more refined build. Compared to the 2019-2024 HO Cummins at rank one, this pick requires confirming every software update and recall was completed. A documented, updated early DT is still a great truck, but an undocumented one is a gamble.

10. 2011-2018 Ram 3500 CP4 Cummins

The 2011-2018 Ram 3500 with an undocumented CP4.2 fuel pump ranks tenth because it is not a bad truck, but a bad transaction. The Bosch CP4.2 high-pressure pump can fail without warning and send metal debris through the entire fuel system—rails, injectors, lines, and tank—routinely resulting in a five-figure repair. Without records of a prior pump replacement, an installed disaster-prevention kit, or a CP3 conversion, this is a gamble.

This truck is for no one who cannot verify the fuel system's history. It trades away the reliability of the 2013-2018 Cummins with documentation, which is the same platform but a safer purchase. Compared to the 2019-2024 DT, it is cheaper but carries a tail risk that can wipe out any savings. The only rational approach is to price the risk into the offer or walk away entirely.

How we ranked these

We ranked Ram 3500 model years by measuring capability per dollar of risk. Capability was weighted by powertrain output, tow ratings, payload, and chassis refinement. Risk was weighted by known failure points, especially the CP4.2 fuel pump on pre-2019 diesels, emissions system complexity, and the cost of unplanned downtime. We also factored in cabin quality, towing technology, and documented maintenance history as value multipliers.

We deliberately ignored brand loyalty, subjective styling, and anecdotal reliability reports without statistical backing. We did not penalize trucks for age alone, nor did we reward the highest horsepower figures without considering real-world duty cycles. We excluded deleted or tampered emissions trucks from top rankings because they carry legal and resale risk. We also ignored the sticker price as a primary metric, focusing instead on total cost of ownership and the probability of a catastrophic repair event.

Related questions

Does the Ram 3500 hold its value better than the 2500?

Generally the 3500 dually with the Cummins holds value well because the buyer pool—contractors, hotshot haulers, large fifth-wheel owners—needs the payload specifically. Single-rear-wheel 3500s overlap heavily with 2500s and track closer to them.

Is the Aisin transmission worth seeking out over the 68RFE?

For heavy, frequent towing, yes. The Aisin is the heavier-duty unit and pairs with the High Output Cummins. For lighter duty the 68RFE is adequate, and a well-maintained one is not a reason to walk away from an otherwise clean truck.

Can I convert a CP4 truck to a CP3 pump?

Yes, CP3 conversion kits are a well-established aftermarket path and are commonly done preemptively. A truck that already has one documented is worth a premium over an identical truck without it, because it removes the single largest tail risk on the platform.

How many miles is too many on a 6.7L Cummins?

The engine itself routinely exceeds 300,000 miles with maintenance. Mileage matters far less than service records, duty cycle, and the condition of everything around the engine—transmission, front end, emissions hardware, and frame.

Is a dually Ram 3500 worth the extra cost?

If your pin weight exceeds a single-rear-wheel's payload capacity, yes. Duallys carry more, are more stable with tall trailers, and back up straighter under heavy tongue load. But they cost more in tires and are awkward in urban settings. Decide by payload, not tow rating.

What is the best Ram 3500 for a first-time heavy tower?

A 2013-2018 DS with the 6.7L Cummins and documented fuel-system history is the best value. It offers mature emissions, strong torque, and a comfortable cabin at a steep discount to fifth-gen trucks. Verify CP4 records or a bypass kit before buying.

Are gas Ram 3500s reliable for towing?

Yes, the 6.4L Hemi is stout and simpler than the diesel. It lacks the Cummins' torque and engine brake, so it suits lighter or occasional towing. Maintenance is cheaper, and there is no CP4 or DEF risk. For weekly heavy hauling, the diesel is worth the premium.

FAQ

What is the best year for a used Ram 3500?

The 2019-2024 fifth-generation trucks are the best overall, thanks to the refined cabin, available rear air suspension, and the high-output 6.7L Cummins with up to 1,075 lb-ft of torque behind the Aisin AS69RC. For better value per dollar, the 2013-2018 fourth-generation trucks offer a fully mature 6.7L diesel and strong towing at a much lower price.

Should I avoid any Ram 3500 model years?

No year is categorically bad, but common-rail diesels through 2018 carry the CP4.2 high-pressure fuel pump, and a failure can send metal debris through the entire fuel system. Post-2007.5 trucks also have emissions equipment that needs verification. Avoid any diesel where fuel-system and emissions history cannot be documented.

Is the 6.4L Hemi gas engine a good choice in the Ram 3500?

Yes. At 410 hp and 429 lb-ft it is a stout gas option with a much lower entry price and no CP4, DEF, or DPF to maintain. It gives up torque, towing capacity, and fuel economy to the Cummins, so it suits lighter-duty or occasional towing rather than daily heavy hauling.

How reliable is the Cummins 6.7L diesel in the Ram 3500?

The block and internals are exceptionally durable, and 300,000-plus miles is common with proper maintenance. The known concerns sit around the engine rather than inside it: the CP4 pump on pre-2019 trucks and emissions-system upkeep on post-2007.5 trucks.

What is the towing capacity of a Ram 3500 dually?

A properly equipped dual-rear-wheel 3500 with the high-output Cummins can tow up to roughly 37,000 pounds with a gooseneck hitch. Fifth-wheel figures typically land in the 30,000-35,000-pound range. Real-world limits depend on cab configuration, axle ratio, and how much payload the truck is already carrying.

Are Ram 3500s expensive to maintain?

The diesels are. Oil changes are large-volume, fuel filters are a scheduled item, DEF is a consumable on newer trucks, and a CP4 event runs into five figures. The 6.4L Hemi is cheaper to maintain but still requires heavy-duty parts and labor rates.

What is the CP4.2 fuel pump issue?

The Bosch CP4.2, used in 2011-2018 Cummins trucks, can fail catastrophically, sending metal debris through the entire fuel system. Repairs often exceed $10,000. Mitigations include documented pump replacement, a disaster-prevention kit, or a CP3 conversion. Always verify fuel-system history before buying.

Should I buy a deleted emissions Ram 3500?

No. Deleted trucks carry legal exposure, fail inspections in many jurisdictions, are harder to insure, and are harder to resell. A truck that has been deleted and reassembled with mismatched parts is worse than either state. Confirm DPF, EGR, and DEF systems are intact and functioning.

How important is a pre-purchase inspection?

Critical. Use a diesel shop, not a general mechanic. Pull the free NHTSA recall lookup by VIN, ask for actual service invoices, and test drive with weight if possible. A seller who cannot produce records on a $40,000 diesel has told you something important.
