Causes and Solutions for Chucking When Using a B&W Turnoverball With a 5th Wheel Adapter

Chucking usually occurs while accelerating and decelerating, but if this is happening while regular driving, there is something else going on. As you are using the B&W Turnoverball # BWGNRK1012 to tow a fifth wheel camper, I assume you are using an adapter of some sort.

If it is an adapter that bolts to an existing king pin, like the Convert-A-Ball # CAB-C5G, then it could be that the height setting range is not enough to properly work with your truck/trailer set up causing some porpoising. This will kind of feel like a rocking sensation front to back. There is also a little more play between a gooseneck coupler and ball compared to a 5th wheel hitch so it could be that as well.

If you are using something like the Reese Goose Box # RP85FR, it could be the air bag that supplies cushion is underinflated and or has developed a leak. Easy way to check for a leak would be to fill it up with air, and then use a spray bottle filled with water to spray all the connections. If you see bubbles at any of the connections, you definitely have a leak and will need the # RP86007. If you do not see any bubbles anywhere, you might just need to add or release air before towing to get it set properly.

If the trailer is also being towed nose high, then there may not be enough weight on the ball. You could try loading the trailer front heavy to see if this solves the issue.

With all that being said, the best way to rid yourself of the chucking will be to convert back over to a full fifth wheel set up. The B&W Companion # BWRVK3500 will be for a long bed truck and the B&W Companion Slider # BWRVK3400 will be for a short bed truck. Both of these hitches will also fit very nicely into your current # BWGNRK1012. Both of these will require a true fifth wheel king pin, so if you are using an adapter like the # CAB-C5G, you would simply need to unbolt it and you will be on your way. If you have a Goose Box installed, you will either need to switch back to the original king pin, or go with something like the Trailair Air Ride # LC158778 would be a good option. Though this is specifically for a 1621 pin box number, the air cushion will definitely help smooth out the ride.
