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.

Not real hard to install, uninstalling the old one was harded. Install took 1 hour. I have a flatbed truck, hooked it into the ball backed under the trailer, raised the back of the Reese up into position with a jack, in to the bolts, given to spec's, take for a test run....

IF you have a gooseneck ball and a fifth wheel RV, then this is the perfect match for your rig! The Reese Goosebox changes everything! Easier hook up and unhooking. Smooth ride and easy installation. etrailer has plenty of videos for review and installation, plus you can call them and ask about it if you have any questions. I have had it for a year now and just installed it on its second camper and I would have it any other way! It is exactly what you need!

This Goosebox is heavy but I was able to get it installed by myself with help from my wife while tightening the bolt. When UPS freight delivered this, the driver was kind enough to load it directly into my truck so I did not have to lift it up. Using my truck I was able to back it into position where it went in effortlessly. I first took the zirk fitting out so I did not break it. The Goosebox was shored up using 2X4 pieces and then strapped in place, so it was in position while backing it up to the fifth wheel. This is a well made and stout pinbox replacement. The one issue I do have is that the air inflation gauge is very hard to see. Basically it is a black bar inside a black hole. The next time I am hooked up, I intend to put some white or other bright colored paint on the bar for easier viewing. No more lifting the heavy hitch to of the bed to use the truck. As always etrailer is hard to beat, fast shipping, expert advice, great prices.
Review from a similar Goose Box in Gooseneck and Fifth Wheel Adapters
My camper is 4 yrs old. I was using a gooseneck offset adapter to hitch fifth wheel to truck B&W gooseneck hitch. I upgraded to the Reese 16k Goosebox with a recommendation from a friend. I am absolutely impressed by how this hitch tows. No more chucking, the airbag and shocks add a much needed level of comfort. My camper is a Starcrart AR-One Maxx 26BHS. I’m towing with a 2005 Ram 3500 4x4 CCSB. I am using the B&W offset hitch ball to create more space between the truck cab and camper bulkhead. Highly recommend this hitch to anyone looking to tow their 5’er with a gooseneck ball hitch.

After dealing with the awkward 5th wheel hitch and pin box for many years on several RV's, I decided to try the Goose Box. Absolutely the very best mod I've done on my 2019 Alpine 5th wheel.

Installed on a 18,000 gvwr fifth wheel for use with a 2019 f350 drw. Install straightforward, I did need to shift vertically. I was able to borrow a friends gooseball which helped me pick out the best gooseball in terms of height (I ended up w the desired 7” clearance and the front of my fifth wheel about 1” high). Love the open truck bed and I’ve gotten used to centering the ball (at first I used some white electrical tape on the hitch to help me visually, but now I mostly rely on centering my dually with the fifth wheel sides. Nothing light weight about this unit! I picked up a mini grease gun that I use regularly. I adjust the air pressure to about 40psi, no issues with leaking when we are on the move. Very smooth ride.

Ordered this to replace OEM king pin on my 2019 Solitude 375RES. Due to it being delivered via freight it took a little longer than expected, had to make an appointment to have it delivered, not to big of a deal. The cardboard this comes in is very hefty, as it should be for the weight of the item. As stated by other, there was not any instructions included, easy to find online though. I am not the mechanical type but a little handy with basic tools and it took me about 2.5 hours, this includes taking the old pin box off. Watched a few videos on how people used wood blocks and used the tailgate of the truck to install. I was worried about braking the zerk fitting off so I attached the couple to my goose ball. I than used blocks of wood to shore it up and used the truck and the fifth wheel to line it up. Hooking up is easy. On my test drive I can tell this will handle better, did not have as much chucking as with the fifth wheel hitch. Looking forward to our next camping trip to give it a true test.
Review from a similar Goose Box in Gooseneck and Fifth Wheel Adapters
I have completed the installation of the Reese Gooseneck pin Box 20K on my 2019 Columbus 1492 366RL. The installation went well for 2 people. The installation was done as suggested in the instructions, one step below the original fifth wheel hitch. That actually proved to be too high for my 2019 GMC DenaliHD 4x4 DRW so I moved the hitch to the same position as the original equipment and the height works much better. I was able to unbolt and reset the position of the hitch by myself using the truck bed as a "work bench" and raising and lowering the RV to align the holes. Haven't towed it yet but will soon and provide more info. As you can tell by the photos, the safety chain installation was very easy.

I installed this hitch, in less than 1.5 hours with a little help. hooked up to my truck and pulled my toy hauler. I could not believe the difference. the only complaint is there was only 4 bolt/nut/washer assy. which is legal, and plenty strong. so I used a couple of the old bolts. I did not like the 4 empty holes
Review from a similar Goose Box in Gooseneck and Fifth Wheel Adapters
I finally reached the point where I could no longer remove my standard fifth wheel hitch by myself. My only option was to leave my hitch in the bed of my truck for the entire travel season, April to October for us. Not a good thing when I needed my full bed. After hours of research the Goose Box seemed to be my best option. I had put the Box on our previous fifth wheel but didn't tow it much before we traded it for a 2020 Jayco Pinnacle. I had the dealer change the Box over to the new Jayco. It is by far the best towing, best riding and best handling fifth wheel/truck combo we have ever owned, and that has been a few. Our 2020 F350 has the camera system which makes hookup relatively painless. The 5 pound ball is so much easier to remove than a 200 pound hitch. Well worth the money and highly recommend it.
Review from a similar Goose Box in Gooseneck and Fifth Wheel Adapters
I had changed from a 2500 to a 3500 DRW that happened to include the GM puck system. I was left with a choice: do I spend hundreds on a puck adapter system to allow my old industry standard rail fifth wheel hitch to work with my new truck? Or do I sell it for as much as I can, and change over to something like the Goosebox? In the end, I was able to sell my old fifth wheel hitch and purchase this Goosebox, and the difference cost about as much as the adapter would have cost. Furthermore, the bed of my truck is now eternally empty and usable without needing to climb in and disassemble a heavy hitch, and I even lost a bit of weight in the bed. Yes, the Goosebox is heavy, but it is certainly not heavIER than a normal pinbox plus the weight of my old hitch. If my guess is right, I probably lost 50-100 lbs. To add to that, once the bag is inflated, the ride is so smooth. It's easily one of the best upgrades I did to my truck and trailer setup. Yes, hooking up is SLIGHTLY more complex than a traditional fifth wheel, but the time difference is minutes at most. Less, once you get used to it, or you have a good spotter to help. I kept the old pin box around, because I will want to keep this setup if I ever change trailers!
Review from a similar Goose Box in Gooseneck and Fifth Wheel Adapters
I think this is one of the best “hitch” setups for a 5th wheel. The only downside to this is it is more difficult to hitch up, especially by yourself in a 4door truck, the only other downside is with a short bed the max turn radius is slightly limited with a modern rounded front cap 5th wheel. The benefits of this over a conventional 5th wheel hitch are: you have 100% of your bed available once you disconnect the trailer. No heavy 5th wheel hitch to take in or out. Also the hitch is cushioned with the airbag, the only other downside is cost. You could get an above the bed rail setup or inexpensive 5th wheel hitch if your truck has the puck system for less. However to buy a b&w hitch it is nearly the same. The other downside would be for people who have difficulty getting into the bed to hookup safety chains (required for gooseneck hitch but not for 5th wheel).

This thing is great! Install was a breeze took about 2 hours to install taking my time and torque. All I did was sat the pin box up on cardboard and wooden blocks, then slid the pin box under the king pin when it was close enough. A buddy and I installed it. Towing is very smooth and nice and easy. No bucking. Everything is great with this gooseneck pin box. I'm extremely happy and I'm even at the camp site right now reviewing this! Thanks etrailer.
Review from a similar Goose Box in Gooseneck and Fifth Wheel Adapters
After one year of use the Goosebox has been a joy to pull with. Initial hookup is a learning curve compared to a traditional 5th wheel hitch but simple and quick after a few trips. Found a bed mounted camera eases the hookup process and love the open space of our truck bed when unhooked!

The Reese Goosebox was simple to install and arrived in timely manner. I won't know until later next week how it tows. This is my second purchase from etrailer and they did not dissappoint.

I have a flat bed f-450. It is a hydra-bed. I worked with etrailer, Lippert and Reese. They all gave good advice and made certain this would work. It did, it's done and I'm towing. This is not my first purchase from etrailer. Always good service.

Review from a similar Goose Box in Gooseneck and Fifth Wheel Adapters
Installed very easily on my Grand Design 31MB, Towing with a 2019 F350 short box and have about 7" of bed rail clearance once the box is aired up. Using the B&W 4" offset, can get close to 75-80 degree turns Hardest part was tracking down a 220lb torque wrench to get all the bolts secure.
Review from a similar 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.
