Ram 3500 Dually vs. Single Rear Wheel: Which One Do You Need?

· 8 min read

Choose a dually (DRW) Ram 3500 when your trailer's pin weight is high enough to eat up a single rear wheel truck's payload — heavy goosenecks, big fifth wheels, hotshot loads. Choose single rear wheel (SRW) when you want most of the capability with a narrower, cheaper-to-run truck you can park anywhere. Payload, not tow rating, is usually what decides it.

What "dually" actually means

A dually has four tires on the rear axle instead of two, under wider rear fenders. Those two extra tires do three things: they raise how much weight the rear axle can legally carry, they spread the load across more rubber, and they give the truck a wider stance that fights trailer sway. A single rear wheel Ram 3500 has the same frame, the same cab options and the same engines — it just carries less on the back end.

Both are Ram 3500s. Around here people still say "Dodge 3500," and we know exactly what you mean.

Across the 2026 Ram 3500 lineup, maximum payload runs up to 7,590 pounds and GVWR up to 14,000 pounds when properly equipped, with maximum gas towing up to 18,150 pounds. The 3500 starts at $48,155. Ram publishes towing and payload as separate ratings, and they are not interchangeable — more on that below.

Payload is the number that decides it

Here's the math that sends people to a dually. A gooseneck trailer puts roughly 20–25% of its loaded weight down on the ball, and that weight counts as payload, not towing.

  • A 20,000-pound loaded gooseneck puts about 4,000–5,000 pounds in your bed.
  • Add two people, a full fuel tank, a toolbox and a couple of round bales' worth of gear.
  • Now compare that total to the payload on your door jamb sticker.

A single rear wheel truck can run out of payload long before it runs out of tow rating. That's not a Ram problem — it's physics and it's the law. If you're regularly over, the dually isn't a luxury, it's the correct truck.

When single rear wheel is the smarter buy

Plenty of people buy a dually they don't need. If you pull a two- or three-horse gooseneck, a 20-foot stock trailer, or a bumper-pull equipment trailer, an SRW 3500 — or even a Ram 2500 — will do the work and be easier to live with.

Reasons to stay single rear wheel:

  • Cost of ownership. Four tires instead of six, every time.
  • Width. Dually fenders are wide. Drive-thrus, alleys off the square in Snyder, older garages and county road cattle guards all get tighter.
  • Resale in a mixed market. SRW trucks appeal to both work buyers and family buyers.
  • Ride when empty. An unloaded dually is a stiff truck.

Do you need a dually for a fifth wheel?

Not always. Mid-size fifth wheels sit comfortably inside an SRW 3500's ratings. Large triple-axle fifth wheels and toy haulers usually do not. Weigh your trailer loaded the way you actually travel — with water, propane, gear and the side-by-side in the back — then check the pin weight against payload. Dry weight on the brochure has fooled a lot of buyers.

Diesel, chassis cab and the work-truck version of this question

If you're buying for a business, the dually question usually comes bundled with a chassis cab question. A Ram 3500 or 5500 chassis cab with a flatbed or service body is a different truck than a pickup with a gooseneck ball — and often the right one for hotshot, welding and oilfield service work. We keep chassis cabs in stock specifically because of the work that happens around here; see Ram 3500 chassis cab inventory and our commercial and BusinessLink page for upfits, priority service and loaners.

Buying used: what to check on a used Ram 3500 dually

Used duallies work for a living, so inspect accordingly:

  1. All six tires — matched brand, matched wear, correct load rating. Inner rears hide problems.
  2. Gooseneck or fifth-wheel hardware — how it was installed and what it's been pulling.
  3. Service records on the diesel — oil intervals, fuel filters, emissions work.
  4. Frame and bed behind the rear axle — where overloading shows up.
  5. Brakes — the first thing heavy towing eats.

We keep a deep used heavy-duty lot — browse used Ram 3500s, including duallies — and our used inventory runs Ram, Chevrolet, Ford, GMC and Toyota, so we're happy to compare honestly across brands.

What this looks like in Scurry County

Two of every three new units on our lot is a Ram, and heavy duty is the biggest slice. If you want to see an SRW and a dually parked side by side and walk around both, we've got them.

Related FAQs

What is the difference between a Ram 3500 dually and single rear wheel?

A dually has four rear tires under wider fenders; a single rear wheel truck has two. The dually carries more weight on the rear axle and resists trailer sway better. The single rear wheel version is narrower, cheaper to run on tires, and easier to park. Frame, cabs and engines are otherwise the same.

Do I need a dually to pull a gooseneck?

Only if the pin weight exceeds what a single rear wheel truck can carry. A gooseneck puts about 20–25% of its loaded weight into the bed, so a 20,000-pound trailer can add 4,000–5,000 pounds of payload. Weigh your trailer loaded and compare it to the payload on your door jamb sticker.

How much can a Ram 3500 carry?

Maximum payload on the 2026 Ram 3500 is up to 7,590 pounds with a GVWR up to 14,000 pounds when properly equipped, and maximum gas towing is up to 18,150 pounds. Your truck's exact ratings depend on cab, bed, drivetrain and axle, and are listed on the door jamb label.

Is a dually harder to drive every day?

It's wider, not harder. The extra width shows up in drive-thrus, older garages, parking spaces and narrow county roads, and an empty dually rides stiffer than a single rear wheel truck. Most people adjust within a week. If the truck spends most of its life unloaded, single rear wheel is usually the better daily driver.

Does a dually cost more to maintain?

The main difference is tires — six instead of four, every replacement cycle. Oil changes, filters and brake service are comparable. Ask our service department for a maintenance estimate on the specific truck you're considering; we're open Saturdays 7:30 to 4.

How Much Can a Ram 2500 Tow?

A properly equipped 2026 Ram 2500 tows up to 20,000 pounds. With the gas V8 the maximum is 17,840 pounds, and maximum payload is 3,930 pounds. Your actual rating depends on cab, bed, drivetrain, axle ratio and hitch type — the number on your door jamb and trailer hitch label is the one that counts. 2026 Ram 2500 towing and payload, by the numbers Rating 2026 Ram 2500 Maximum towing, gas Up to 17,840 lbs Maximum towing, properly equipped Up to 20,000 lbs Maximum payload Up to 3,930 lbs Transmission TorqueFlite HD 8-speed automatic Cab configurations Regular Cab, Crew Cab, Mega Cab Bed lengths 6'4" or 8' (66.4" between the wheel wells) Starting MSRP $46,855 Those are ceiling numbers. A Crew Cab 4x4 with a heavy option list weighs more than a Regular Cab 4x2, and every pound of truck comes out of what you can pull. Treat the published maximum as the best case for one specific build, not a promise about the truck in your driveway. Gas or Cummins? What actually changes your tow rating The single biggest lever on a Ram 2500's tow rating is the engine. The 6.7L Cummins Turbo Diesel makes 430 horsepower and 1,075 lb-ft of torque, and it's what gets a 2500 to the 20,000-pound end of the range. The gas V8 tops out at 17,840 pounds. Torque is the part that matters when you're pulling a gooseneck out of a caliche pit or climbing out of the Colorado River breaks on US-84. Diesel also changes how the truck behaves on a long grade with 14,000 pounds behind it — you hold speed instead of hunting for gears. Whether it's worth the money depends on how you use the truck. If you tow a stock trailer or a 30-foot gooseneck most weeks, the Cummins pays for itself in drivability and resale. If you tow a bass boat to Lake J.B. Thomas twice a month and haul a toolbox the rest of the time, the gas 2500 is a lot of truck for less money. About 38% of the new trucks on our lot are diesels, so we can put you in either one and let you drive both back to back. Conventional, gooseneck and fifth-wheel towing are different ratings A Ram 2500's highest tow numbers come from gooseneck and fifth-wheel setups, because the load sits over the rear axle instead of hanging off the back bumper. Conventional bumper-pull ratings are lower. Conventional (bumper pull): receiver hitch, weight-distributing hitch for heavier loads. Cattle trailers, equipment trailers, travel trailers. Gooseneck: ball in the bed, over the rear axle. The standard around here for stock and flatbed trailers. Fifth wheel: a plate in the bed. Most common on big travel trailers. If you're ordering a truck to tow a gooseneck, get the factory prep package. Retrofitting is doable, but a factory setup is cleaner and keeps the ratings straightforward. Towing capacity and payload are not the same number This trips up more buyers than anything else. Towing capacity is what you can pull. Payload is what the truck itself can carry — people, fuel, tools, and the tongue or pin weight of the trailer. A gooseneck typically puts 20–25% of its loaded weight down on the ball. Hook a 16,000-pound trailer to a 2500 and you've just put roughly 3,200–4,000 pounds into the bed before anyone climbs in. That's payload, not towing, and it's usually the number that runs out first. It's also the main reason people step up to a Ram 3500. How to find your truck's exact rating Open the driver's door and read the tire and loading label for GVWR and payload. Find the trailer weight rating sticker (commonly on the door jamb or in the glove box) for your specific build. Weigh the truck loaded the way you actually drive it, then subtract from GVWR to get real payload. Add up trailer weight plus everything in it — livestock, water, fuel, feed. Wet weight, not dry. Bring your trailer by the store and we'll do the math with you. No appointment, no credit pull. What this means on West Texas roads Out here a tow rating isn't a spec-sheet argument. It's whether the truck can pull a loaded stock trailer from a pasture north of Hermleigh to the Scurry County Coliseum, or move a skid steer between lease roads without cooking the brakes on the way back down to I-20. Heat, wind out of the southwest, and long distances between anything are the real test — Big Spring is 62 miles, Lubbock 85, San Angelo 99. That's the reason we stock the way we do. Two of every three new trucks on our lot is a Ram, and heavy duty is the biggest piece of it. What a Ram 2500 costs, and what's on the lot in Snyder The 2026 Ram 2500 starts at $46,855.

With the gas V8, maximum towing is 17,840 pounds. The exact rating depends on cab style, bed length, drivetrain, axle ratio and whether you're pulling conventional, gooseneck or fifth wheel. What is the difference between a Ram 2500 and a Ram 3500? Both are heavy duty trucks, but the 3500 has a higher payload ceiling — up to 7,590 pounds versus 3,930 on the 2500 — and can be ordered with dual rear wheels. If your gooseneck pin weight is pushing the 2500's payload, the 3500 is the answer. For most bumper-pull towing, a 2500 is plenty of truck. Do I need a diesel to tow with a Ram 2500? No. The gas V8 still tows up to 17,840 pounds, which covers most livestock trailers and travel trailers. The 6.7L Cummins Turbo Diesel — 430 horsepower and 1,075 lb-ft of torque — is worth it if you tow heavy loads often, tow long distances, or want the easier drive on grades. What is the payload capacity of a Ram 2500? Up to 3,930 pounds when properly equipped. Payload covers passengers, fuel, cargo and the tongue or pin weight of your trailer. Because a gooseneck puts roughly 20–25% of its loaded weight into the bed, payload — not tow rating — is often the limit you hit first. Does the Ram 2500 come with a powertrain warranty? Yes. Every 2026 Ram 1500, 2500 and 3500 comes with a 10-year/100,000-mile powertrain warranty. Ask us for the full coverage terms and what's included on the specific truck you're looking at.
