Will A Rota-Flex Pin Box Provide A Better Ride Quality With A Curt CrossWing 5th Wheel Hitch
Question:
I have a Curt CrossWing 5th wheel hitch. Would a Trailair rota-flex 5th wheel pin provide any additional comfort in my towing ride. What would you tell your father to do. Is the rota-flex really worth the extra money?

Expert Reply:
If you have the Gooseneck versions of the Curt CrossWing ( # C92DR or # C32DR) you unfortunately would not be able to use the Rota-Flex with it. The pivoting head causing too much strain for the single point of contact you have with a gooseneck hitch. If you have the base rail version # C86JR with four points of contact then you would be able to use a Rota-Flex pin box.
As for the ride quality, the pivoting head of the Rota-Flex can help reduce chucking so it would be worth considering with your CrossWing since it only has a rubber pad between the head and shank to absorb chucking. Curt has some customer reviews on their site saying that the combination eliminated all chucking but each situation is going to be different. That being said, the Rota-Flex has a lot of compatibility issues with certain 5th wheel hitches so I try to avoid it to go with a MORryde Cushioned Pin Box instead.
These come with an internal shear spring and glide pads that allow the skid plate to move and absorb road shock and chucking. They also don't have the same compatibility issues with 5th wheel hitches like the Rota-Flex does. To find the correct one for your trailer we'll first need to know your bolt pattern and the GVWR of the trailer. For example, if you had a 1621 bolt pattern and 15k GVWR you could use the # MR84VR.

Would using the blue ox lockout kit allow you to use the rota-flex with the crosswind since that kit converts it to a normal pinbox?
