Do You Need a Dually for a 5th Wheel?

When contemplating a 5th wheel towing setup, a common question that arises is whether you need a dually pickup truck. The short answer is it depends on your specific needs and circumstances. Let's delve into the aspects you should consider to make an informed decision.

Before we dive in, let's clarify what a dually is. A dually, or dual rear wheel vehicle, is a truck with two rear axles. Now, let's consider when you might need one for towing a 5th wheel.

Weight distribution and stability

One of the primary considerations is the Gross Combined Weight Rating (GCWR) of your truck. Towing a heavy 5th wheel can quickly approach or exceed the GCWR of a single rear wheel truck. A dually offers a higher GCWR, providing a safer margin for weight distribution.

Stability is another significant factor. The additional rear tires on a dually provide more contact with the road, enhancing traction and stability, especially when negotiating corners or driving in windy conditions.

GCWR limitations of single rear wheel trucks

Most half-ton trucks (1500 series) and even some three-quarter ton (2500 series) trucks have a GCWR that may not allow towing a fully loaded 5th wheel. Here are some examples:

• Chevrolet Silverado 1500: GCWR of 11,100 lbs for a 6.5' or 8' bed.
• Ford F-150: GCWR of 11,100 lbs for a 6.5' or 8' bed.

GCWR advantages of dually trucks

Dually trucks, typically one-ton (3500 series) or higher, offer significantly higher GCWR. Here are some examples:

• RAM 3500 Dually: GCWR of 18,210 lbs.
• Ford F-350 Super Duty Dually: GCWR of up to 20,000 lbs.

Matching gooseneck and hitch types

Another important consideration is the hitch type of your 5th wheel. Most dually trucks come with a gooseneck hitch in the bed, which provides a more direct connection to the 5th wheel, improving control and stability.

However, not all 5th wheels are compatible with gooseneck hitches. If your 5th wheel requires a rear receiver hitch, you'll need to consider a truck with one, which limits your options to single rear wheel trucks.

Gooseneck hitch benefits

Gooseneck hitches provide several benefits when towing a 5th wheel:

• Better stability and control due to the direct connection.
• Higher weight-carrying capacity, allowing for heavier tow loads.
• Improved maneuverability, making it easier to back up and park.

Rear receiver hitch considerations

If your 5th wheel requires a rear receiver hitch, you'll need to consider a truck with one. Keep in mind that these trucks will typically have a lower GCWR. Additionally, the weight of the 5th wheel is transferred to the rear of the truck, causing it to sag, which can affect handling and safety.

Driving experience and practicality

Driving a dually can offer a more comfortable and confident experience when towing a heavy 5th wheel. The wider stance provided by the additional rear tires results in a more stable and planted feel on the road.

A dually's practicality extends to its larger cargo bed, which can accommodate more gear and supplies. Additionally, many dually trucks come with heavier duty components, ensuring longevity and reliability.

Daily driving considerations

While dually trucks offer many advantages, they also come with some trade-offs. Due to their size and weight, dually trucks can be more challenging to park and maneuver in tight spaces. They also tend to have higher fuel consumption and may have a higher cost of entry compared to single rear wheel trucks.

Towing capability vs. daily use

Consider your towing needs versus your daily driving requirements. If you primarily use your truck for towing and can accommodate the size and weight of a dually, it may be the better choice. However, if you need a more maneuverable truck for daily use, a single rear wheel truck may be more suitable.

Ultimately, the decision to opt for a dually when towing a 5th wheel depends on your specific needs, towing requirements, and driving habits. It's essential to do thorough research and consider all factors before making a decision. And remember, always follow safety guidelines and ensure your truck and 5th wheel are properly equipped and maintained for a safe and enjoyable towing experience.
