The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter part # RP94716 for 16,000 lbs or part # RP94720 for 20,000 lbs have the exact same overall dimensions. The 20,000 lb model has extra internal bracing to give it more strength. They are also both designed to replace the same pin boxes which is a Lippert 1621, 1621HD, and 0719.

With that being said there are adjustments that can be made at the mounting location for the pin box so it is possible that a different set of holes was used, giving the impression that they are different sizes.

Question:

Thank u so much for the information. Now can u tell me how to fix the problem of denting the back of cab of my truck from here.? Can I goosebox to set camper higher ? Do u make something to off set the point of hookup to move the goosebox back in the truck bed? The camper people who installed this for us when we bought the camper seem to think it’s our problem. We seem to think they should have know this wouldn’t work before we ruined the cab of a 70,000.00 truck?? Please help us fix this problem. We have spent another 1,000.00 dollars on a ball offset that gained us only 3 1/2”. Not enough.

If you are having clearance issues between the nose of your trailer and cab of your truck while using the Reese Goose Box, you can use an offset hitch ball like part # 19308 which will move the connection point 5" rearward. However, this particular offset ball only works with Bulldog, Draw-Tite, Hidden Hitch, and Reese hitches. If you have a different gooseneck hitch then please let me know what that is so I can make sure you get the correct one. If an offset hitch ball does not provide the proper turning clearance then you would want to remove the Reese Goose Box and install the original pin box back on the trailer along with a sliding 5th wheel hitch. In order to make sure you get the correct 5th wheel hitch I would need to know the year, make, model, and bed size of your tow vehicle.

There are vertical adjustments that you can make with the Reese Goose Box which can be done by using the lowermost set of bolt holes on the trailer's mounting brackets but this will not help the clearance issues between the nose of your trailer and cab of your truck. It sounds like you have a short bed which is why you are running into issues. The Reese Goose Box is simply not designed to work with most trucks that have a bed shorter than 8' long therefore you will want to consider a standard pin box and sliding 5th wheel hitch. This will however require you to remove the gooseneck hitch you have unless it is a B&W Turnoverball Underbed Gooseneck Trailer Hitch but there will simply be no other options to gain turning clearance with the Reese Goose Box.

Just bought a 10k lb (12k max fill) 5th wheel from a dealer who “set me up” with a reesebox 20k goose ball hitch.... the whole way home (3.5 hours) My trailer is bouncing like a low rider with hydraulics! I now see you offer a 16k version.... could the 20k version straight up be too stiff for my 10k 5th wheel?? Is there ANY way I can adjust this? I dropped the psi to 18 half way down the road but it was still bouncing around all over the place. :( not happy

That's a pretty big discrepancy so the over-rated Goose Box could definitely lead to a rougher ride. Before making the switch you could try lowering the psi even more - the minimum level is 5 psi. If it still doesn't help then switching to the 16K # RP94716 will be your best bet.

I have a B&W Turnoverball Underbed Gooseneck Trailer Hitch in my 2013 f-250 6.7 engine with the 6 1/2 foot bed. I have my B & W hitch adjusted to offset the pin connection about 4 1/2 inches. I can turn 90 degrees with a 38 foot camper with this set up.thinking about installing the reese goose neck air ride coupler. my current 5th wheel is a Lippert LIPP 1116. is the original 5th wheel & goose neck have the same dimensions to pin connection, if so I think I will also need the 5 inch offset adapter. do all of this seem okthanksdon

Your Lippert pin box 1116 will be replaced with the Reese 5th Airborne Premium Fifth Wheel Air Ride Coupler - Standard 12-1/2" Wide Air Ride Pin Box # 5AB-S500-700 . This pin box will be the same length and pin location, so it should not impact your turning clearance at all. The only noticeable change you will feel is the reduction in jarring and chucking. It will be a much smoother ride. The combination of your current hitch with this pin box is a better option for towing comfort. If you are looking to change to the Goosebox adapter for not needing to load a 5th wheel hitch, the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94716-61301 is compatible. Then you will need an offset ball like the 4" Offset Ball for B&W Turnoverball Gooseneck Trailer Hitches # BWGNXA4085 . the 4 inch offset is the largest offered for your hitch, so your turning clearance will be restricted slightly.
