Question:
I tow a 2002 Montana 3280RL with 2005 F250 6.0 short bed. Hitch is Reese #30051 slider. Lippert 1621 pin box. This is a new setup for us. I am experiencing a lot of chucking, which makes the ride uncomfortable. Im not sure about up and down motion because of the excessive chucking. Im not sure which pin box would be best. Theres the Mot/Ryde, TrailAir and Airborne. We are retired on a fixed budget, so price is a major factor. The prices range from $500-$1200. Can be even more expensive if I purchase the wrong one, and need to replace it, thus doubling the expense. Help!

For the Lippert 1621 pin box the most inexpensive option that will improve the chucking and overall ride quality when towing your 5th wheel trailer is the Rota-Flex, # LC328330. It uses a pivoting mechanism and rubber compound to dampen chucking. This version is rated for 18,000 pounds. there is also a 21,000 pound version, # LC328329.
The next step up is the 5th Airborne # 5AB-E1621-16K which uses both a shock and an air bag to reduce chucking and vertical movement. It will be more effective at reducing chucking than the Rota-Flex pin boxes above. It is rated for 16,000 pounds. There is also a 21,000 pound version, # 5AB-E1621-610.
The cream of the crop is the Flex Air, # LC328492, rated for 18,000 pounds. It also has a shock and air bag but also has the pivoting mechanism and rubber dampening associated with the Rota-Flex models to provide the best ride quality. I have linked video reviews of these 3 types of pin boxes for you.
Any of them will improve the ride quality. Some will just help more than others.
