Fifth Wheel Pin Box Upgrade Recommendations for a Trailer with a Lippert 1621 Pin Box

Question:

I have a 2014 345 Open Range 5th wheel. Which pin box should I use? I am looking at the Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000 lbs

If your 2014 345 Open Range Fifth Wheel Trailer has a Lippert 1621 pin box the Trailair Flex Air 5th Wheel Pin Box # LC328492 that you referenced would be an excellent option.

The only option I would recommend over this would be for if you have a short bed truck. Then I would recommend the cushioned Sidewinder part # RP61422 that will give you the turning clearance your trailer would need to make tight turns without having to use a slider hitch.

To determine what pin box you have you will need to check the plate or sticker on it that will list this info as well as other trailer frame info.
