Swap gooseneck to 5th wheel

[flyingjack]

Got rid of last gooseneck work trailer (retired); currently have B&W turn-over ball I use for 5th wheel. Need to avoid pickup rail damage caused by uneven turns; I tend to push limits on equipment.

Any reviews of B&W Companion 5th Wheel Gooseneck Hitch.

Any reviews for a shock absorbing pin box like: Trailair Flex Air 5th Wheel Pin Box

Thanks for any information.

Jack
