Fifth-Wheel-to-Gooseneck Adapter

This unique coupler lets you tow your fifth-wheel trailer with your gooseneck hitch. It is air ride equipped to ensure that less stress is put on your trailer's frame than is typical with traditional king pin adapters. Simply replace your trailer's existing pin box with the Goose Box and you'll be ready to go.


Eliminate Chucking and Jarring

The Goose Box is designed to absorb road shock for a smooth, stable ride. The internal air bag can be adjusted to give you just the right amount of support, so you will lose the bounce but avoid the stiff, rigid ride that occurs when towing with an overinflated air bag. Also included in the Goose Box are dual shock absorbers, which ensure that compression of the air bag occurs in a controlled fashion. This extends the life of the air bag.


Cutaway Diagram of Reese Products Goose Box
  1. The air bag can be adjusted to provide a smooth ride for both your truck and trailer. Because it is fully enclosed, it's protected from UV exposure and shielded from road hazards.
  2. Dual shock absorbers help to reduce bounce and relieve stress on your trailer frame.
  3. The integrated pivot tube allows the Goose Box to move fore and aft, minimizing chucking.
  4. The gooseneck coupler attaches to the 2-5/16 inch ball on your gooseneck trailer hitch.

Video Transcript for Reese Gooseneck and Fifth Wheel Adapters RP94623 Review

Today we're going to review part number RP94623. This is the Reese Goose Box 5th Wheel to Gooseneck Air Ride Coupler Adapter for Lippert 1621 and 1715 pin boxes and it has a 20,000 pound weight capacity. Now this is an air ride coupler which will let you tow your 5th wheel trailer with your gooseneck hitch. Basically this coupler right here, this Goose Box will replace your standard pin box on your 5th wheel trailer. It is endorsed by Lippert Components Inc. so it will not affect the warranty on their trailer frames. Has a fully enclosed airbag on the inside and dual shocks, it'll provide cushion and absorb road shock.

Does improve the handling and the overall ride. The other nice thing is it will decrease both vertical shock, which is the bounce, and the longitudinal shock, also known as chucking. It does limit the strain on the truck and trailer frames. The pivot tube on it, it also helps to minimize jarring by allowing fore and after movement. It is a simple bolt-on installation, right back here is what you'd bolt onto your trailer. The mounting hardware is all included.

The finish, this is a sturdy steel construction with a nice powder coat finish for corrosion resistance. Specs on it again, it is designed to replace the Lippert 1621 and 1716 pin boxes. The towing capacity is 20,000 pounds. Tongue weight capacity is 4,000 pounds and it is designed to fit on the industry standard gooseneck ball size of 2-5/16 diameter. Comes with a limited lifetime warranty. Now basically, couple features on this just want to show you, is when you go to hook it up, what you would do is make sure it's in the locked position.

And you can see here where it's green it says locked, red it says unlocked. If you leave it in the lock positions, what that allows you to do is when you drop that onto your gooseneck ball, it will automatically click into place and lock it into position. Once, now if you're ready to unhook from your trailer, then what you need to do is pull on this cable, there's a little knob right here that you want to hook onto this, right into this little opening. That will hold this into the unlocked position and unlock that from the ball. Then you can raise up your trailer and pull your truck away. But when you do go to hook up, all you have to do is make sure this is not hooked on, make sure it's released and in the locked position.

Then once it drops on, it will automatically click up into place. The other thing is right here is the air valve to fill the air bags on the inside and to help you out on that, usually they say not to go over 50 psi range. Usually keep it in about 35 to 40 psi, but what else helps you out, there's a label right here on this lower part, it'll be yellow at the bottom and yellow at the top and then green right in the middle. At the top, it'll say too much air and at the bottom in yellow, it would say add air. Then the green middle it says max 50 psi. You want to keep it in the green and actually there's a nice thing, this has an automatic air relief valve in it, so that keeps you from over-inflating it and actually that feature will actually help you get the correct air pressure in there. Basically what you could do is once this is all hooked up, fill this, put the air in it until you get it to the green area and then just add a few more pounds. Then what happens is go ahead and drive the vehicle, step on the break a few times. What that will do is push that excess air, it'll vent off so it'll get rid of that excess air, and then that should put you right at or near the green area, which is your most optimum pressure. It will also help you get the right amount of air on the airbags in there. But that, oh one last thing I do want to mention is on your tradition gooseneck coupler locks will not work on this design on this goose box. They do recommend the wheel lock should be used instead. But that should do it for the review on part number RP94623, the Reese Goose Box 5th Wheel to Gooseneck Air Ride Coupler Adapter for Lippert 1621 and 1716 pin boxes with a 20,000 pound weight capacity. .

We no longer could use the trailer 5th wheel attachment on our trailer we had to convert it to a goose neck for the new tow vehicle. We chose Reese Goosebox 20k with air ride. It's perfect, the air takes the jarring away from trailer as well as the truck. The Rocky Mountains can be unforgiving. And it solved all issues we had prior. Worth the investment. ETrailer is stellar. Customer service is top notch. 374770

I've had this product for over a year now. It looks almost brand new. I've used it to tow my 16,000 lbs trailer approximately 12,000 miles without any issues. I'm very happy with it. No heavy or bulky fifth wheel king pin hitch in the truck bed to deal with. 336945


Comments

This hitch still works great. There are a few rust spots that develop. Cleaning them off and touching them up with some black rust preventative paint does the job.

Have used this for 6,000 miles without any issues. It sure nice being able to unhook the 5th wheel and have a flat truck bed. I have a magnetic nail plate on a vertical rod that I use as a guide to place the hitch over the ball. Works really well. 474218

Review from a similar Reese Goose Box in Gooseneck and Fifth Wheel Adapters


Hi, Last September, I bought a Reese Goose Box from Lisa and Sandy. Both went way beyond the call of duty to not only help me out with technical specifications, but to get the Goose Box to my door in a minimal amount of time. I have waited to give a review of the Goose Box, so that I could give a meaningful, time tested, review. Now that I have had the Goose Box for several months, I can say that buying the Goose Box has transformed my pulling a 14,000 lb 5th wheel from a harrowing, bone jarring experience, to one in which I cannot even tell that the travel trailer is behind me. The truck that I use, is a Ford F350 dually that has a diesel engine in it. The trailer is a toyhauler that weighs about 14,000 lbs when loaded. Prior to having the Goosebox, I used a 5th wheel to gooseneck adaptor when pulling the trailer. If the road was glass smooth, the ride was glass smooth. However, add a bridge, an expansion joint, a small bump in the road, or even the slightest imperfection, and the trailer owned the truck. The trailer would cause the truck to chuck fore and aft. This movement translated into the back of the seats to impact the backs of the occupants of the truck, to the point of discomfort. The whole experience was right on the edge of not being worth using the travel trailer. Now that the Goose Box has been installed, the trailer is virtually undetectable when going down the road. There are many times, when I actually will quickly glance in the mirror, to make sure that the trailer is still there. The Goose Box has transformed the ride quality, to where I will continue to enjoy towing a travel trailer. Great product! Great place to buy from! 500497

Review from a similar Reese Goose Box in Gooseneck and Fifth Wheel Adapters


This was very easy to install and works great. I replaced my 5th wheel King Pin with this GooseBox and I do not regret it one bit. It is very easy to hook up and use, along with every easy indicators showing if it is locked on the Gooseneck ball or not. I followed the installation instructions where they suggest installing 1 bolt hole lower than the 5th wheel King pin, but I ended up adjusting down 1 more bolt hole for more appropriate clearance between the trailer and the bed rails of my truck. 472435

Review from a similar Reese Goose Box in Gooseneck and Fifth Wheel Adapters


This hitch is a perfect solution I at first bought a king pin to to goose neck solid adapter because I also pull a 30 goose neck flatbed trailer often and couldn't be switching back and forth between different style of hitches. The problem was I was getting some bad chucking when pulling the new 33 ft toy hauler I just bought it was bad enough I think leaving it like that would of damaged the trailer, not to mention it sucked to drive, with this hitch it smoothed virtually all that out you will get what I would call some surging if you hit a bridge or big bump in the road but pulls way better. I won't own another fifth wheel trailer without an air ride hitch! The camper also gets a lot better ride on those pothole filled roads, trying to get to that great camp sight. 401030

Review from a similar Reese Goose Box in Gooseneck and Fifth Wheel Adapters


This is the only way to haul a 5th wheel type of trailer. --But need a long bed, as this does not slide back. Way solid hook up. No latch problems that can have the trailer come out and wipe out your truck bed!! Easy to hook up. No rattling like my old slider hitch. Terrific. I would highly recommend this hitch, very strong and well made. I will never go back to the 5th wheel. Yes, I upgraded to a long bed truck. No big difference over the short one, not that much longer wheel base. And go dually! Shudda done this years ago--but this was just invented!! I did try the adapter being bolted on to the 5th wheel. Not good. Physics is all wrong. 499710

Review from a similar Reese Goose Box in Gooseneck and Fifth Wheel Adapters


I think that the Reese gooseneck should be a stock option for the original buyer. If the truck has a gooseneck hitch the trailer should come with a Reese gooseneck hitch option. It was not hard to put on but you do need help with installation. Once you use the gooseneck hitch you will never go back to the 5th wheel hitch again. E trailer was great with the ordering and shipping process. A bit more of a process coming to Canada but still pretty easy. I would recommend e trailer to everyone ! 251016

Review from a similar Reese Goose Box in Gooseneck and Fifth Wheel Adapters


I bought a goose box fifth wheel adapter for gooseneck hitch in my flatbed pickup because I did not want the fifth wheel hitch in the way. It took 80% of the road bounce out, very easy to install. Excellent people to deal with, everything they told me about the hitch was correct, and hitch performs very good. Great company. I would highly recommend this hitch for anyone who has flatbed truck with a gooseneck. 339246

Product works great at reducing bounce and chucking on rough roads. The major problem I have is having to reinflate the air bag before you go camping and before you leave to go home. I believe Reese could have done better on this for something priced over a grand! 498059

Review from a similar Reese Goose Box in Gooseneck and Fifth Wheel Adapters


Best decision I've made for my 5th wheel. Was using B&Ws companion slider before it. It is a good hitch but heavier than heck to lift in and out of truck. Reese's goose box hooks up easily and has good ride with the air bag. 369357

This is a great hitch. Worked out just like I'd hoped. The RV pulls great and I barely feel it back there. If you want to utilize your gooseneck ball and not have to hassle with a fifth wheel hitch, this is the way to go. 341848

  • 5th Wheel Trailer Hitch or Gooseneck Adapter for a 2016 GMC Sierra 2500 with Factory Prep Package
  • First the best hitch for towing any given trailer is going to be the matching hitch type. So in other words for a 5th wheel trailer use a 5th wheel hitch. For a gooseneck trailer use a gooseneck hitch. Since you want to tow a 5th wheel trailer I recommend a 5th wheel hitch.

  • Could Fifth Wheel Trailer Chucking Come From Broken Frame On Trailer

When you experience the chucking can you look at the trailer and see where the movement is coming from?

  • Why Does Using Convert-A-Ball 5th Wheel to Gooseneck Void Warranty on Lippert 5th Wheel Frame
  • I can explain it. The use of a 5th wheel to gooseneck adapter such as # CAB-C5G increases the distance from the trailer frame to where it couples to the gooseneck ball. The distance is greater in this instance compared to having the trailer coupled to a regular 5th wheel trailer hitch. The extra distance puts more stress on the trailer because of increase leverage. This leverage can damage 5th wheel trailer frames, specifically up where the pin box attaches but where you can't really...

  • As long as the recessed area in the bed measures at least 12 x 12 inches or so, most of the adapters we offer would work just fine for you. The best practice is to use a fifth wheel hitch for a fifth wheel, but in your case that isn't practical. Many adapters can be rough on the fifth wheel's frame, and some frame warranties will even state that an adapter shouldn't be used for that very reason. The Reese Goosebox is an exception.

Along with the Lippert 1621 and 1621HD, the # RP94623 will also fit the Lippert 0719 and the Fabex PB-600 series. When used with the # RP61301 spacer plate, either Goosebox will also fit the Lippert 0115, 1716 and 1116. I've linked you to product description videos for each Goosebox model.

  • Recommendation to Tow 5th Wheel Trailer with Gooseneck Hitch
  • I may have a solution for you, however the Gen-Y Gooseneck Coupler # 325-GH-7061 referenced in your question is a gooseneck coupler inner tube that will pair with an existing outer tube. This will not allow you to tow a fifth-wheel trailer with a gooseneck hitch on your truck. For an option that will allow you to do this while also leaving the truck bed free when not towing, I recommend looking into a Reese Goose Box like part # RP94623. This is designed to replace the pin box on a...

  • Comparing the 16K and 20K Reese Goose Box Adapters
  • The measurements for Reese 20K Goose Box # RP94623 and 16K Goose Box # RP94622 are the same. The difference is that the 20K model is built with heavier steel stock to handle the higher capacity.

  • Would a Reese Goosebox Clear the Bed Rails of a Truck that are 20 inches Tall with B and W Turnover
  • I think you mean to say that you have a B and W Turnoverball gooseneck hitch and not a Turnaround as that's not something B and W carries. The Goosebox should have no problem clearing the bed rails and tailgate of your truck as long as your truck isn't lifted. 20 inch tall bed rails would work just fine with the Goosebox. It basically would simulate the same height as a fifth wheel hitch relative to where the pin box would attach on the trailer. The Gooseboxes are pin box specific...

  • Can A Reese Goose Box Be Used on a Short Bed Truck for Sharp Turn Clearance
  • The Reese Goose Box, # RP94623, does not offer additional clearance for short bed trucks above what the stock pin box would offer. To get extra clearance you would need to use an offset gooseneck ball, if available for the gooseneck trailer hitch you have. If you can tell me the make and model of the gooseneck hitch I can determine if we have an offset ball. To determine if the truck would have enough clearance to make tight turns you will need to plug a few measurements into this...

  • Does Towing a 5th Wheel Trailer with a Gooseneck Trailer Hitch Damage the Trailer Frame
  • Actually, it depends on the type of adapter that is used. An adapter such as # CAB-C5GX1216 can put too much stress on a 5th wheel trailer frame. But it isn't just the rigid mount design. It is the distance from the gooseneck ball to the 5th wheel pin box. The distance is greater between the hitch and the pin box with this sort of adapter and that creates extra leverage on the trailer frame. Another type of adapter is the Reese Goose Box. This is the only adapter approved by Lippert,...

  • Towing 5th Wheel Trailer with Ford F-350 That Has a 8 x 9-foot Flatbed and Goose Neck Hitch
  • Since you need to tow your new 5th wheel with a goose neck-equipped truck you may be able to avoid the need for installing a 5th wheel hitch like the Reese Low-Profile # RP30054. Your best option may be to install a replacement pin box called a Goose Box, made by Reese, that allows 5th wheel trailers to be pulled by a goose neck hitch. A Goose Box such as one of the three units shown on the linked page bolts on in place of a standard 5th wheel pin box. There may be a bolt-on replacement...

  • Need 5th Wheel to Gooseneck Adapter That Wont Void the Warranty on My 2015 Keystone Montana Trailer
  • When it comes to using a fifth wheel to gooseneck adapter, the only adapter endorsed by Lippert Components Inc. (the frame manufacturer for your Keystone) is the Reese Goose Box. The Goose Box actually replaces the existing pin box on a fifth wheel trailer and since it doesn't cause any additional stress in either the trailer frame or hitch, using this will not affect the warranty on the Lippert trailer frame. Lippert does not endorse the use of any other adapter. The Goose Box is made...

  • Do Gooseneck to Fifth Wheel Adapters Stress Trailer Frames
  • The fifth wheel to gooseneck adapters like part # CAB-C5G do put a bit more stress on the frame of the trailer as they allow for more movement when compared to a fifth wheel hitch that has 4 contact points to stabilize the connection. At the base of the connection with an adapter you have a gooseneck hitch ball which would pivot and move easily whereas at the base of a fifth wheel hitch there is a wide footprint to stabilize side-to-side movement. That being said, we sell a ton of these...

  • Can an Air-Ride Pin Box Be Used With a Gooseneck to Fifth Wheel Hitch Adapter
  • It's not recommended to use a gooseneck adapter with an air ride pin box. The air ride feature allows front to back and side to side movement to cushion shock. This movement would damage the pin box or the adapter. The Reese Goosebox would be an excellent option for you. The Goosebox is an air ride adapter that would replace your existing pin box and would allow you to hitch directly to the gooseneck ball. The Goosebox is only compatible with certain pin box models. The manufacturer...

  • Recommended Equipment Needed to Tow 5th Wheel with 2018 Chevy Silverado 6-1/2 foot w/Prep Package
  • Since you have a 6-1/2 foot bed on your 2018 Chevrolet Silverado 2500 the best Convert-A-Ball Adapter for you to use would be part # CAB-C5GX1216 that has a 7-1/2" offset. Most trailer manufacturers void the warranty if an adapter is used so sometimes it is better to go with a Goose Box like part # RP94623, 20K for 1621 or 0719 boxes, part # RP94622 16K for 1621 boxes, or part # RP94622-61301, 16K for 1716 boxes. If you have the factory installed gooseneck hitch on your 2018 Silverado...

  • Will Using a Reese Goose Box Provide Enough Height Clearance Between Truck and Trailer
  • First, you should not have to have a taller ball to use a Reese Goose Box. It couples to a standard 2-5/16 inch ball. The Goose Box measures 19.2 inches from the center of the lowest front bolt hole down to the bottom of the coupler that couples to the ball. Compare this to your current set up. You need 5 or 6 inches between the tops of the bed sides and the bottom of the 5th wheel trailer overhang. If you determine a taller ball is needed you could use one. Regarding the horizontal...
