Towing heavy trailers—whether for recreation, work, or transport—requires the right equipment to ensure safety, efficiency, and flexibility. One of the most versatile tools available for trailer owners is the 5th wheel to gooseneck adapter, a specialized towing accessory that bridges the gap between two popular hitch styles. This adapter allows you to tow a 5th wheel trailer using a gooseneck hitch in your truck bed—saving space, time, and money.

Understanding the Two Hitch Types

Before diving into the benefits of the adapter, it helps to understand the key difference between a 5th wheel and a gooseneck hitch.

• 5th Wheel Hitches are typically larger, semi-permanent installations that mount into rails in the bed of a pickup truck. They use a kingpin and plate system, similar to what you’d see on a semi-truck.
• Gooseneck Hitches, on the other hand, use a ball mount—usually installed directly over or slightly in front of the rear axle. This type of hitch is more compact and often preferred by those towing horse trailers, flatbeds, and other heavy-duty equipment.

The problem? These two systems are not directly compatible. That’s where the 5th wheel to gooseneck adapter comes in.

The Adapter’s Core Purpose: Hitch Compatibility

The primary function of a 5th wheel to gooseneck adapter is to make a 5th wheel trailer compatible with a gooseneck hitch system. Instead of switching back and forth between two different hitch types or investing in an expensive 5th wheel hitch, trailer owners can install an adapter that allows their 5th wheel trailer to be hitched directly to a gooseneck ball.

This adapter essentially acts as a conversion device, mounting to the kingpin of the trailer and extending downward to couple with the gooseneck ball in the truck bed. The result is a secure, efficient connection that eliminates the need for multiple towing setups.

Benefits of Using a 5th Wheel to Gooseneck Adapter

1. Space-Saving Design

Unlike the bulky 5th wheel hitch system, gooseneck hitches take up less space and can often be flipped down or removed when not in use. This leaves your truck bed open for hauling other items when you’re not towing.

2. Cost Savings

A quality 5th wheel hitch can cost upwards of $1,000, not to mention the installation. With an adapter, you avoid that expense if you already have a gooseneck setup.

3. Increased Flexibility

This adapter gives you the best of both worlds. Whether you're switching between different types of trailers or just need a more universal solution, the adapter allows for quick transitions without changing your entire hitch system.

4. Easier Storage and Installation

Most adapters are lightweight and easy to install, usually bolting onto the kingpin of the trailer or clamping in place without permanent modifications.

Types of 5th Wheel to Gooseneck Adapters

There are several designs available to suit different towing preferences and trailer configurations:

• Kingpin Adapters: These bolt or clamp around the kingpin and extend down to couple with a gooseneck ball.
• Rail-Mounted Gooseneck Hitches: These drop into 5th wheel rails already installed in the bed and provide a gooseneck ball mount.
• Cushioned or Offset Adapters: Designed to reduce road shock and provide additional clearance between the truck cab and trailer, especially helpful for short-bed trucks.

Each of these styles serves a unique need, but all provide the same core function: seamless connectivity between two otherwise incompatible systems.

What to Consider Before Using One

While 5th wheel to gooseneck adapters offer convenience, there are some considerations to keep in mind:

• Warranty Issues: Some trailer manufacturers may void their frame warranty if an adapter is used, due to the added stress it may place on the trailer structure.
• Ride Quality: Adapters without shock-absorbing features can lead to a rougher ride or increased wear on the trailer frame.
• Weight Capacity: Always verify the adapter’s weight rating and ensure it exceeds or matches your trailer’s GVWR (Gross Vehicle Weight Rating).
• Legal Compliance: In some regions, specific adapter types may not be approved for road use. Always check local regulations.

Is a 5th Wheel to Gooseneck Adapter Right for You?

If you own a 5th wheel trailer but only have a gooseneck hitch installed—or if you want to avoid cluttering your truck bed with a large 5th wheel hitch—this adapter can be a game-changer. It’s especially useful for RVers, farm and ranch workers, and anyone who needs to switch between various towing applications with minimal hassle.

In short, the 5th wheel to gooseneck adapter offers a practical, economical solution that enhances towing versatility without compromising safety—when chosen and used correctly.

Conclusion

Towing doesn’t have to be complicated. A 5th wheel to gooseneck adapter simplifies your setup, saves you money, and makes your truck bed more usable when not towing. Whether you’re a full-time traveler or a weekend hauler, this small investment can make a big difference in your towing experience.

If you’re considering adding one to your rig, make sure to match it to your trailer specs and hitch system—and enjoy the freedom it brings.
