2012 Ram 3500 Towing Capacity Chart by Engine and Cab Guide 2026
The 2012 Ram 3500 towing capacity reaches up to 22,750 pounds when properly equipped. That top rating applies to a Regular Cab 2WD long bed dually with the 6.7L Cummins Turbo Diesel, 68RFE automatic transmission, 4.10 axle ratio, 30,000 pound GCWR, and 12,000 pound GVWR.
Most 2012 Ram 3500 trucks tow less than that. Cab style, 2WD or 4WD, single rear wheel or dual rear wheel, axle ratio, payload, and transmission all change the final number.

This guide breaks down the official pickup towing chart first, then explains payload, GCWR, axle ratio, fifth-wheel towing, and how to verify your exact truck before hooking up a trailer.

2012 Ram 3500 Towing Capacity Quick Answer
For most owners, the safest answer is not the highest advertised rating. It is the rating for your exact cab, drivetrain, rear-wheel setup, axle ratio, transmission, and door-jamb payload sticker.
The official 2012 Ram 3500 pickup chart shows the highest rating at 22,750 pounds for the Regular Cab 2WD long bed ST dually with the 6.7L Cummins Turbo Diesel, 68RFE 6-speed automatic, and 4.10 axle ratio. That same row lists a 30,000 pound GCWR and 5,280 pound payload. The official 2012 Ram 3500 pickup towing chart lists this configuration in the Ram 3500 Heavy Duty towing tables.
Here is the quick range:
| 2012 Ram 3500 Setup | Typical Max Trailer Range |
|---|---|
| SRW 6.7L Cummins models | About 9,300 to 17,150 lbs |
| DRW 6.7L Cummins models | About 8,900 to 22,750 lbs |
| 3.42 axle automatic models | Often around 8,900 to 10,150 lbs |
| 3.73 axle models | Often around 12,850 to 14,150 lbs |
| 4.10 axle Max Tow DRW models | Up to 22,750 lbs |

2012 Ram 3500 Towing Chart by Cab and Drivetrain
The official pickup chart uses one engine family for these rows, the 6.7L Cummins Turbo Diesel. The big differences come from cab style, bed length, 2WD or 4WD, SRW or DRW, transmission, and axle ratio.
Use this table as a practical summary of the most important configurations from the official chart.
| Cab and Drivetrain | Rear Wheels | Best Listed Axle and Trans | GVWR | Payload | GCWR | Max Trailer |
|---|---|---|---|---|---|---|
| Regular Cab 2WD Long Bed ST | DRW | 4.10 Auto | 12,000 lbs | 5,280 lbs | 30,000 lbs | 22,750 lbs |
| Regular Cab 2WD Long Bed SLT | DRW | 4.10 Auto | 12,000 lbs | 5,230 lbs | 30,000 lbs | 22,700 lbs |
| Regular Cab 4WD Long Bed ST | DRW | 4.10 Auto | 12,200 lbs | 5,030 lbs | 30,000 lbs | 22,300 lbs |
| Regular Cab 4WD Long Bed SLT | DRW | 4.10 Auto | 12,200 lbs | 5,000 lbs | 30,000 lbs | 22,300 lbs |
| Crew Cab 2WD Long Bed ST | DRW | 4.10 Auto | 11,500 lbs | 4,330 lbs | 26,800 lbs | 19,050 lbs |
| Crew Cab 4WD Long Bed ST | DRW | 4.10 Auto | 12,300 lbs | 4,710 lbs | 29,100 lbs | 20,950 lbs |
| Crew Cab 4WD Long Bed SLT | DRW | 4.10 Auto | 12,300 lbs | 4,650 lbs | 28,900 lbs | 20,650 lbs |
| Mega Cab 4WD Short Bed Longhorn | DRW | 4.10 Auto | 10,500 lbs | 2,980 lbs | 26,000 lbs | 18,350 lbs |
| Crew Cab 4WD Long Bed Laramie | SRW | 4.10 Auto | 10,100 lbs | 2,730 lbs | 24,000 lbs | 16,500 lbs |
| Crew Cab 4WD Short Bed Laramie | SRW | 4.10 Auto | 10,100 lbs | 2,850 lbs | 24,000 lbs | 16,600 lbs |
Ram’s chart shows why two trucks with the same 6.7L Cummins badge can have very different limits. A Regular Cab 2WD dually with 4.10 gears sits at the top, while heavier luxury trims and SRW trucks lose capacity because base weight rises and rear axle capacity changes.
How the 6.7L Cummins Changes Towing Ratings
The 6.7L Cummins Turbo Diesel is the only engine shown in the 2012 Ram 3500 pickup towing chart rows reviewed for this guide. It is the reason the truck can reach heavy fifth-wheel and equipment-trailer numbers.
For 2012, the Cummins output depends on transmission. MotorTrend reports 350 horsepower and 650 lb-ft of torque with the standard 6-speed manual, and 800 lb-ft of torque with the available 6-speed automatic. MotorTrend’s 2012 Ram 3500 review also notes the 22,750 pound Max Tow rating and 30,000 pound GCWR for Max Tow models.
That does not mean every automatic truck gets the top tow rating. The 3.42 axle automatic rows often have much lower GCWR and trailer ratings than 4.10 axle rows.
The engine supplies the torque. The axle ratio, drivetrain, rear wheels, GVWR, and GCWR decide how much trailer the truck is rated to move.
Why Axle Ratio and GCWR Matter Most
GCWR means Gross Combined Weight Rating. It is the maximum allowed weight of the loaded truck and loaded trailer together.
The formula is simple:
Available trailer weight equals GCWR minus loaded truck weight.
That is why axle ratio changes the number so sharply. In the official chart, many 3.42 axle automatic trucks show a 17,000 pound GCWR, while 4.10 axle dually Max Tow configurations reach 30,000 pounds.
The same truck can jump thousands of pounds in rated trailer capacity when the axle and GCWR change. For example, the Regular Cab 2WD ST dually automatic is rated at 10,150 pounds with the 3.42 axle, 14,150 pounds with the 3.73 axle, and 22,750 pounds with the 4.10 axle.
Payload still matters. A high GCWR does not erase GVWR, rear GAWR, tire ratings, receiver limits, or fifth-wheel pin weight.
2012 Ram 3500 Payload Capacity and Pin Weight
Payload is the weight your truck can carry on itself. That includes passengers, cargo, hitch hardware, tools, fuel effects, accessories, and trailer tongue or pin weight.
The official chart shows payload as low as about 1,510 pounds on some heavily equipped Mega Cab SRW configurations and as high as 5,280 pounds on the Regular Cab 2WD ST dually Max Tow configuration. The top towing row lists 12,000 pound GVWR, 6,717 pound base weight, and 5,280 pound payload.
Fifth-wheel pin weight often runs around 15 to 25 percent of loaded trailer weight. A 16,000 pound fifth-wheel can place roughly 2,400 to 4,000 pounds on the truck before passengers and hitch weight.
That is why a dually usually wins for heavy RV towing. It gives you more rear axle rating and payload headroom.
For more payload-specific math across Ram trucks, use Truck Guider’s Ram payload capacity chart before choosing a trailer.
Conventional vs Fifth Wheel Towing Limits
A bumper-pull trailer and a fifth-wheel trailer load the truck differently. Conventional towing loads the receiver hitch behind the bumper area, while fifth-wheel and gooseneck towing place weight in the bed near the rear axle.
The official Ram chart gives Max Trail values, but your hitch hardware still has its own rating. Do not assume the receiver, fifth-wheel hitch, tires, or rear axle can handle the chart number without checking labels and documentation.
| Towing Type | What To Check First | Why It Matters |
|---|---|---|
| Conventional trailer | Receiver rating, tongue weight, weight distribution | Hitch hardware can limit the setup before GCWR does |
| Fifth-wheel trailer | Pin weight, rear GAWR, payload sticker | Pin weight can consume payload quickly |
| Gooseneck trailer | Bed hitch rating, rear axle load, tire rating | Heavy equipment trailers often add serious pin load |
| RV towing | Loaded trailer weight, water, cargo, passengers | Brochure dry weight is not the camping-ready weight |
The 2012 Ram 3500 can be a strong fifth-wheel platform, but only when the loaded trailer weight and pin weight fit the truck’s actual rating.
SRW vs DRW Towing Capacity Differences
The biggest real-world split is SRW versus DRW. SRW means single rear wheel. DRW means dual rear wheel, often called a dually.
SRW Models
SRW models are easier to live with as daily drivers. They are narrower, simpler to park, and usually more convenient when the truck is not towing.
But SRW trucks have lower rear axle capacity than dually models. In the official chart, many SRW 4.10 automatic configurations fall around 16,400 to 17,150 pounds of maximum trailer rating, depending on cab and trim.
DRW Models
DRW models are built for heavier trailer work. They usually bring higher payload, higher rear GAWR, and more stability with tall fifth-wheel trailers or equipment trailers.
The highest 2012 Ram 3500 tow ratings all come from DRW configurations. The top 22,750 pound rating is a Regular Cab 2WD long bed dually with the 4.10 axle and automatic transmission.
If you are shopping used and planning to tow a large fifth-wheel, start with the dually ratings first.
What the 2012 Ram 3500 Max Tow Package Adds
The highest 2012 Ram 3500 towing number comes from the Max Tow type setup, not from every diesel badge. The key ingredients are the 6.7L Cummins Turbo Diesel, 68RFE automatic transmission, 4.10 axle ratio, DRW, and the correct high-GCWR configuration.
The official chart shows the top row at 30,000 pound GCWR and 22,750 pound Max Trail. MotorTrend also reported that 2012 Ram 3500 Max Tow models reached a 22,750 pound maximum trailer weight rating and up to 30,000 pound GCWR.
Used buyers should verify equipment, not just trim. A Laramie badge, Cummins badge, or dually bed does not prove the truck has the top rating.
Check these items before trusting a listing:
- VIN or original build sheet
- Axle ratio
- Transmission
- SRW or DRW setup
- GVWR and payload sticker
- Hitch rating
- Tire load rating
For a VIN-focused approach, Truck Guider’s Ram towing capacity by VIN guide fits this step well.
Pickup vs Chassis Cab Ratings Compared
Do not mix the 2012 Ram 3500 pickup chart with the 2012 Ram 3500 chassis cab chart. These are different trucks for different use cases.
Pickup ratings apply to standard consumer Ram 3500 trucks with factory pickup beds. Chassis cab ratings apply to commercial trucks that may receive flatbeds, service bodies, utility boxes, dump bodies, or other upfits.
The 2012 Ram 3500 chassis cab chart uses different assumptions and shows different drivetrain combinations, curb weights, and commercial ratings. The official 2012 Ram 3500 chassis cab towing chart should only be used for chassis cab trucks.
If your truck has a factory pickup bed, use the pickup towing chart. If it started life as a cab-and-chassis truck, use the chassis cab chart and account for the installed body.
How To Check Your Exact 2012 Ram 3500 Rating

The safest number is always the rating for your specific truck. Online charts are useful, but the truck in your driveway may have different equipment.
Follow this process before towing near the limit:
- Check the door-jamb sticker. Look for GVWR, GAWR, tire size, and payload information.
- Confirm the axle ratio. Use the build sheet, axle tag, differential tag, window sticker, or dealer VIN lookup.
- Confirm the transmission. Manual and automatic trucks do not share the same torque output or towing chart rows.
- Identify SRW or DRW. Dually models usually carry more payload and rear axle capacity.
- Match the exact cab and bed. Regular Cab, Crew Cab, and Mega Cab ratings are not interchangeable.
- Check hitch ratings. Your receiver, fifth-wheel hitch, or gooseneck hitch can limit the setup.
- Weigh the loaded truck. A CAT scale ticket gives you real front axle, rear axle, and combined weights.
This is also where comparing against a three-quarter ton makes sense. Truck Guider’s Ram 2500 towing capacity guide can help if you are deciding between a 2500 and 3500.
Best Takeaway for 2012 Ram 3500 Owners
The 2012 Ram 3500 towing capacity is excellent for its era, but only the right configuration reaches the top number. The maximum verified pickup rating is 22,750 pounds, tied to a Regular Cab 2WD long bed dually with the 6.7L Cummins Turbo Diesel, 68RFE automatic, 4.10 axle, and 30,000 pound GCWR.
For most owners, payload and rear axle rating matter as much as trailer rating. That is especially true with fifth-wheel RVs.
Before towing near the limit, match your VIN, axle ratio, transmission, cab, rear-wheel setup, door sticker, and hitch hardware to the official chart.
FAQ
What Is the Maximum Towing Capacity of a 2012 Ram 3500
The maximum 2012 Ram 3500 towing capacity is 22,750 pounds when properly equipped. The official chart ties that number to a Regular Cab 2WD long bed dually with the 6.7L Cummins Turbo Diesel, automatic transmission, 4.10 axle, and 30,000 pound GCWR.
How Much Can a 2012 Ram 3500 Dually Tow
A 2012 Ram 3500 dually can tow anywhere from about 8,900 pounds to 22,750 pounds, depending on cab, drivetrain, trim, axle ratio, and transmission. The highest dually rating belongs to a Regular Cab 2WD long bed automatic with 4.10 gears.
What Is the 2012 Ram 3500 Fifth Wheel Towing Capacity
The chart’s highest Max Trail number is 22,750 pounds, but fifth-wheel towing also depends on payload and pin weight. For large fifth-wheel RVs, check the door sticker, rear GAWR, tire rating, and loaded trailer pin weight before trusting the trailer-weight rating alone.
Does the 2012 Ram 3500 6.7L Cummins Tow More Than a Gas Model
The 2012 Ram 3500 pickup towing chart reviewed here is centered on the 6.7L Cummins Turbo Diesel configurations. The diesel’s high torque and heavy-duty drivetrain make it the key engine for the truck’s top tow ratings.
How Do I Find My Exact 2012 Ram 3500 Tow Rating
Find your exact tow rating by matching your VIN, cab, bed, 2WD or 4WD setup, SRW or DRW layout, axle ratio, transmission, GVWR, GCWR, and payload sticker to the official towing chart. Do not use the highest online number unless your truck matches that row.
Is Payload More Important Than Towing Capacity for a Fifth Wheel
Payload can be more limiting than trailer rating for a fifth-wheel. A fifth-wheel places pin weight in the bed, and that load counts against payload, rear axle rating, tire rating, and GVWR.
What Is the GCWR of a 2012 Ram 3500 Max Tow
The highest official 2012 Ram 3500 pickup row lists a 30,000 pound GCWR. That row is the Regular Cab 2WD long bed ST dually with the 6.7L Cummins Turbo Diesel, 68RFE automatic transmission, and 4.10 axle ratio.
