Single Rear Wheel vs. Dually: Which Truck Is Better for Towing?

Choosing the right truck depends on the type of trailer you plan to tow, how much weight you’ll be hauling, and how often you’ll be towing. Let’s compare them.

What Is a Single Rear Wheel (SRW) Truck?

A Single Rear Wheel (SRW) truck has one tire on each side of the rear axle. That means the truck has two front tires and two rear tires, for a total of four wheels.

Popular SRW truck examples:

• Ford F-250
• Ford F-350 SRW
• Chevrolet Silverado 2500 HD
• Chevrolet Silverado 3500 HD SRW
• GMC Sierra 2500 HD
• GMC Sierra 3500 HD SRW
• Ram 2500
• Ram 3500 SRW

SRW trucks are popular because they balance towing capability with everyday drivability. For people who only tow occasionally, an SRW truck may be all they need.

What Is a Dually (DRW)?

A Dual Rear Wheel (DRW) truck has two tires on each side of the rear axle. That means the truck has two front tires and four rear tires, for a total of six wheels.

Dually trucks are designed for maximum stability and heavy-duty towing. They’re commonly used by contractors, farmers, equipment haulers, hotshot trucking businesses, RV owners towing large fifth wheels, and commercial operators.

Advantages of a Single Rear Wheel Truck

SRW trucks are ideal for many trailer owners. Benefits include:

• Easier to park
• Narrower overall width
• Better for city driving
• Lower tire replacement costs
• Better fuel economy in many situations
• More comfortable as a daily driver

For people who only tow occasionally, an SRW truck may be all they need.

Advantages of a Dually

Dually trucks are built for serious towing. Benefits include:

• Greater payload capacity
• Higher towing capacity
• Improved stability
• Better weight distribution
• Increased traction under heavy loads
• Better handling with large gooseneck and fifth-wheel trailers

Which One Tows Better?

For heavy trailers, a dually generally provides greater stability and higher payload capacity than an SRW truck. The extra rear tires help reduce side-to-side movement and improve control, especially when towing:

• Large gooseneck trailers
• Heavy equipment trailers
• Livestock trailers
• Large fifth-wheel RVs

However, many properly equipped SRW trucks are fully capable of towing moderate-sized trailers within their manufacturer ratings.

Quick Comparison

Payload Capacity

One of the biggest differences between SRW and DRW trucks is payload. A dually typically offers a higher payload rating because the additional rear tires help support more weight.

This is especially important when towing trailers that place significant weight on the truck, such as gooseneck trailers, fifth-wheel trailers, and heavy equipment trailers. Always verify the payload rating for your specific truck before towing.

Everyday Driving

If your truck doubles as your daily vehicle, an SRW model is often easier to live with. Advantages include:

• Easier parking
• Better fit in parking garages
• Easier navigation through narrow streets
• Simpler car wash access
• Less rear-end width

A dually’s wider rear fenders can make daily driving more challenging in tight spaces.

Maintenance Costs

Both truck types require regular maintenance. However, dually trucks typically have two additional rear tires, higher tire replacement costs, and slightly higher maintenance expenses over time. These additional costs may be worthwhile for buyers who frequently tow heavy loads.

Which Truck Is Right for You?

Choose an SRW truck if you:

• Drive your truck every day
• Tow light or moderate loads
• Want easier parking
• Prefer lower ownership costs
• Rarely tow very heavy trailers

Choose a dually if you:

• Tow heavy gooseneck trailers
• Haul construction equipment
• Tow large fifth-wheel RVs
• Operate a commercial hauling business
• Need maximum payload and towing stability

Frequently Asked Questions

Is a dually safer for towing?

A dually can provide increased stability when towing heavy trailers because of its additional rear tires and higher payload capacity. The appropriate truck depends on the trailer’s weight and the manufacturer’s ratings.

Does a dually tow more?

Many dually trucks are rated to tow more than comparable SRW models, but towing capacity varies by manufacturer, engine, axle ratio, cab configuration, and equipment.

Is a dually harder to drive?

A dually is wider than an SRW truck, which can make parking, lane positioning, and navigating tight spaces more challenging. Many owners adapt quickly with experience.

Can an SRW truck tow a gooseneck trailer?

Yes. Many properly equipped SRW trucks can tow gooseneck trailers, provided the combined weight stays within all manufacturer towing, payload, axle, and hitch ratings.

Final Thoughts

The best truck isn’t always the biggest truck—it’s the one that matches your trailer and how you plan to use it. If your truck is primarily a daily driver and you tow only occasionally, a single rear wheel truck may be the better fit. If you regularly haul heavy equipment, large gooseneck trailers, or commercial loads, a dually may provide the added stability and capacity you need.

Choosing the right combination of truck and trailer helps improve safety, towing performance, and long-term reliability.
