Best Truck for Towing a 5th Wheel: Key Factors to Consider
When you’re ready to invest in a 5th wheel RV, the next major decision is choosing the best truck to tow it. Fifth wheels are popular among RV enthusiasts for their spacious interiors, residential-style builds and smoother towing experience. But they come with a significant weight that requires a heavy-duty truck to tow safely. Understanding what to look for in a truck can make a world of difference in both the safety and overall enjoyment of your camping trips. So, we’re here to help you break down the key factors to consider when choosing the best truck for towing a 5th wheel and make an informed decision on your next purchase.
Understanding the Basics: Why Choose a 5th Wheel?
Before diving into truck specifications, it’s helpful to understand what makes a fifth wheel different from other types of RVs. Fifth wheels are designed to attach to a hitch located in the bed of a truck, right over the rear axle. This design improves weight distribution and stability, so towing a 5th wheel is often smoother than a traditional travel trailer. Because of the unique hitch placement, the best truck for towing a 5th wheel is often a heavy-duty pickup capable of handling the weight and dimensions of these larger RVs.
Fifth wheels range in weight from around 7,000 pounds for smaller models to over 20,000 pounds for luxury options. This wide range makes it critical to choose a truck that exceeds the towing capacity needed for your specific 5th wheel model.
Key Considerations When Choosing a Truck for Your Fifth Wheel
Towing Capacity
The tow capacity of the truck is the most crucial factor when selecting a truck that’s compatible with your 5th wheel. Towing capacity refers to the maximum amount of weight a truck can safely tow without causing damage to the vehicle or posing a safety risk.
To calculate the towing capacity you need, you’ll want to know the Gross Vehicle Weight Rating (GVWR) of the fifth wheel you’re considering. The GVWR includes the dry weight of the RV plus any additional cargo, water, and propane. Most fifth wheels have a sticker near the entrance or a section in the owner’s manual that lists the GVWR. If you’re looking at fifth wheels for sale at Crossroads Trailers, our team can help you find this information.
For example, if your 5th wheel’s GVWR is 15,000 pounds, you’ll need a truck with a towing capacity that matches or exceeds this number. The higher the towing capacity, the more options you have in terms of the size and type of fifth wheel you can tow.
Payload Capacity
While tow capacity gets most of the attention, payload capacity is equally important. Payload refers to the total amount of weight a truck can carry in its bed and cab, including passengers, gear, and the hitch. The best truck for towing a 5th wheel needs to have a payload capacity that can accommodate the weight of the hitch plus any cargo in the bed.
Fifth-wheel hitches typically weigh between 150 and 300 pounds, so you’ll need to factor that into your payload calculations. If you’re bringing along a family or hauling extra gear, ensure the truck’s payload capacity can handle the additional weight without exceeding limits.
Bed Size and Hitch Compatibility
A 5th wheel hitch takes up a significant amount of space in the truck bed, so bed size is another critical consideration. Most people opt for long-bed trucks (eight feet), as they offer the most room for the hitch and allow for a more straightforward towing experience. Long beds also reduce the risk of the trailer making contact with the cab during sharp turns.
However, many newer short-bed trucks (about six feet) can still tow a 5th wheel using a sliding hitch. A sliding hitch allows the hitch to move back slightly during turns, preventing the trailer from hitting the truck’s cab. If you prefer a short-bed truck for daily driving, this option might be worth considering, but it comes with added costs for the special hitch.
Engine Power
The engine is the heart of your truck, and it plays a vital role in towing performance. The best truck for towing a 5th wheel typically comes equipped with a diesel engine, which offers superior torque for hauling heavy loads. Torque is the force that turns the wheels and is crucial for pulling a heavy trailer up hills or starting from a standstill.
That said, gasoline engines can still be powerful enough for smaller 5th wheels, particularly if you’re not planning on long-distance or mountainous towing. Diesel trucks, while often more expensive upfront, tend to offer a longer engine life when towing consistently heavy loads.
Transmission and Braking
When towing a 5th wheel, your truck’s transmission and braking system need to be up to the task. Automatic transmissions with manual shift modes are often recommended for towing, as they allow more control over shifting when going uphill or downhill. This helps prevent overheating and increases overall towing efficiency.
Additionally, your truck’s braking system is critical. Many trucks designed for towing come with an integrated trailer brake controller, which helps synchronize the truck’s braking system with the brakes on the 5th wheel. This improves stopping power and reduces wear on your truck’s brakes.
Rear Axle Ratio
A truck’s rear axle ratio affects how efficiently it can tow a 5th wheel. A higher axle ratio, such as 4.10:1, provides more pulling power at the expense of fuel economy. Trucks with a lower axle ratio (e.g., 3.55:1) may be more fuel-efficient but could struggle with heavy loads.
When choosing the best truck for towing a 5th wheel, it’s important to strike a balance between power and efficiency. If your 5th wheel is on the heavier side, consider opting for a higher rear axle ratio to ensure smooth towing performance.
