Top 6 Best Fifth Wheel to Gooseneck Adapters

If your next road trip needs you to haul along heavy trailer at the back of your vehicle, your trip checklist should start with ensuring your fifth wheel and gooseneck hitches are compatible.

Fifth wheel hitch and gooseneck both do the same job. They allow your tow vehicle to drag your cargo conveniently. However, their mechanical assembly is different, therefore, making them incompatible.

Their incompatibility lies from your tow vehicle having a gooseneck hitch while your travel trailer has a fixed fifth wheel hitch. These structures make them impossible to use together. This is due to the trailer kingpins and gooseneck hitches basically not linking together.

One logical solution, and probably the first that will come to your mind is to completely replace the gooseneck hitch with something like a slider hitch. Then again, doing so comes with significant snags. First, especially if your tow vehicle is a truck, is giving up your truck bed space and versatility. The other is having to take your truck to a professional garage to safely dismount your gooseneck hitch.

Rather than going through so much effort and financial expenses, a sound approach is to simply put in an adapter. Hitch adapters will help modify your trailer kingpin to allow it to lock securely in the gooseneck hitch.

What You Need to Know about a Fifth Wheel to Gooseneck Adapter

You probably had a lot of hits when you typed in on your search bar “fifth wheel to gooseneck adapters.” The results which may offer many models and types could overwhelm you. Knowing the factors to consider in picking the right adapter will get you the appropriate one. And, not the “nice to have” adapter.

Some essential factors you need to go through in choosing a fifth wheel to gooseneck adapter are listed below. These criteria are brought by gauged and recognizable components.

With so many models in the market, it’s hard to spot whether one is what you need. No adapter is perfect all around, each kind has its own style to tailor to your exact need and vehicle configuration.

Picking a fifth wheel to gooseneck adapter is not an overnight decision. Ask yourself the following questions before shelling out that money.

  • What adapter size do I need?
  • What manner of setup do I need?
  • Do additional features matter?
  • How much is my budget?

Adapter Sizes

The adapters we are looking for come in three sizes; 12, 15, and 17 inches. The unwritten rule is that 12-inch adapters are for 11 to 12-inch measurements, 15-inch adapters for 13 to 14-inch measurements, and 17-inch adapters for 15 to 16-inch measurements.

Measurement Suggested Adapter Hitch Size
11″ 12″
12″ 12″
13″ 15″
14″ 15″
15″ 17″
16″ 17″

You want to make sure you have the correct measurements. A common error is measuring the distance from the truck bed to the kingpin plate on an even or level trailer. Always measure from the top of the gooseneck ball to the kingpin plate. This is because the height of the adapter measures how high the trailer is lifted from the top of the ball, or from inside the hole from the bottom of the adapter to the top).

The following steps help you to properly measure;

  1. Set the truck under the camper
  2. Level the trailer or camper
  3. Measure from the top of the ball hitch down to the bottom of the king plate on your camper

Note that the measurements of the adapter are not adapter hardware’s total height. So, do not try to measure the outside of the adapter or you will get a measure larger than its rating.

Do not go for a fixed height adapter if you are unsure of the measurements. There are adjustable height models that allow you to modify your clearance, but they could be pricey. In the end, your preference between fixed and adjustable height adapters will depend on how much you are planning to spend.

Setup Types

Not all fifth wheel to gooseneck adapters are created identical. As a matter of fact, how the adapter is fitted can have a direct effect on the level of security when you drag an altered fifth wheel connector to a gooseneck ball truck hitch.

The three main setup types are;

  • Adapter completely replacing the trailer pin box
  • Adapter replacing the fifth wheel hitch
  • Adapter bolts over the kingpin lube plate

You will get a better understanding of each type as it gets discussed ahead.

Common Features of Gooseneck to Fifth Wheel Adapters

Any fifth wheel to gooseneck adapter allows you to tow a serious load of weight, but as an added value for your money, manufacturers have added features that make their products stand out. Consider security, safety, and cushioning as the main areas to look out for.

Parking your truck and trailer and leaving it unattended, shouldn’t make you feel unsafe that one might tamper with your setup, or worst drive off with your important goods. Couplers that locks with a padlock are convenient security features to have if you want peace of mind.

Putting together and rigging your RV trailer and your truck can be risky, so you must have your full attention while doing it. Some adapters come with remote release features that let you disconnect from the hitch without needing to climb into the bed of the truck. The remote release uses a handle attached to a steel cable and helps avoid accidents and injuries.

Driving around with reduced noise and minimized hardware wear and tear is ideal, right? Thanks to cushioned adapters, this experience can be achieved. Cushioning may either be mechanical or pneumatic. This technology makes for a smooth ride as it helps eliminate destabilizing 360° or up and down shaking.

For total security, more than a few state laws require safety chains for gooseneck hitches, but not on fifth wheel hitches used on-road. Although, there is no particular mention of which adapters, you can’t go wrong with having them.

Retail Price

The factor that potentially stamps the deal when picking your fifth wheel to gooseneck adapters is the price tag. An average adapter runs between $400 to $500. Anything below is cheap as well as anything above is expensive.

Being the critical link between your towing vehicle and the trailer, hitch adapters need to be strong, durable and made of heavy solid steel. This justifies the price. There may be some that go beyond $500 mark, but surely, they offer top-quality performance.


Best Fifth Wheel to Gooseneck Adapters

Understanding What Makes a Great Fifth Wheel to Gooseneck Adapter

A number of brands may prove to be a good choice for a fifth wheel to gooseneck adapter, but for unbiased scrutiny, here are some criteria we used to identify which adapters should make it on our list.

Towing Capacity

One of the significant characteristics of any fifth wheel to gooseneck adapter is the towing capacity. This is the maximum amount of weight that the adapter can safely tolerate. Make sure that the adapter you are getting has a greater towing capacity than you need to avoid damage.

Type

The three main types of fifth wheel to gooseneck adapters vary in their manner of mounting and installation. Here’s a table of their basic characteristics for your easy reference.

Setup A Adapter replacing the trailer pin box
Safety Level Superior
Setup B Adapter replacing the 5th wheel hitch
Safety Level Excellent
Setup C Adapter bolted over the kingpin lube plate
Safety Level Average

The first setup is the most secure option from where the adapter replaces the trailer pin box. It is all in all easier to install than the two other setups but usually needs the most maintenance.

Setup B offers a secure connection by replacing the fifth wheel hitch. This gives an excellent safety level, but it may use up more space than the others. This is ideal for six foot or longer truck beds.

An average safety level is what the third setup offers. This type has the adapter bolded over the kingpin lube plate. This results in it being the most compact among the three.

Product Dimensions

Details about the adapter’s dimensions are significant for a number of things. Not just so you know how much space it will take up on your garage when you dismount it, but even more so on your truck bed when you use it.

Maximum Tongue Weight

This factor is completely different from the towing capacity. The maximum tongue weight is the greatest extent of downward force your hitch can handle.

Your maximum tongue weight should be less than the towing capacity, like 10 to 20% of that number. Load your trailer efficiently by having 60% of the weight located in front of the axle. A trailer with well-distributed weight assisted with correct tongue weight makes the rig form a straight line leaving your camper entirely horizontal.

Product Weight

These adapters are considerably bulky and can weight up to 160 pounds. If you are planning on mounting and removing them often, better go for a lighter model. Also, consider that driving around with it without an attached trailer can make it a dead weight and just increase your fuel consumption.

This feature, as well as the many others mentioned above, may add up to the price tag. In the end, it is really your budget that will let you know which fifth wheel to gooseneck adapter is the best.


Frequently Asked Questions (FAQs)

Q: Are safety chains needed in using a fifth wheel to gooseneck adapter?

A: Yes. There are state laws that require you to use safety chains when towing any haul. Most adapters have two hook ended chains that can be fixed to the safety chain loops in the truck bed. Such a safety feature keeps your RV trailer attached to your tow vehicle even when the adapter mechanism miscarries.

Q: Will my trailer warranty get voided with using a fifth wheel to gooseneck adapter?

A: This is still a gray area; therefore, you should really think hard before getting this gear. There are trailer frame manufacturers that imply that adapter use for hooking up to tow vehicle will void the warranty.

A legal standpoint argues otherwise. Warranty can only be legally voided if and when the adapter directly causes damage. This is based on FTC’s Magnuson-Moss Warranty Act. This act indicates that hinting that a warranty is voided simply by using an adapter will not stand up in court.

Q: Is owning a fifth wheel to gooseneck adapter high-maintenance?

A: As with most gears, maintenance is constantly essential. The simplest way yet the biggest part of this regular maintenance is checking your adapter for marks of wear and tear, or damage that might result in failure.

Some adapters may require to be greased and oiled every once in a while. This is to reduce the friction of moving parts when going over rough roads.

There are models of fifth wheel to gooseneck adapters that have internal airbags. Such designs need to be re-pressurized every time you need to hitch or unhitch. This may be a little inconvenient as you may have to pull up at gas stations to make use of their air machines.
