Anti-chucking pin box devices

Search the 5er forum as this topic has come up several times (Mor/ryde vs air pin box). From those who have had both the consensus seems to be they prefer the air pin boxes but they come at a cost and require a bit of maintenance vs the much simpler and cheaper Mor/ryde. I would say if you do a lot of long distance towing go for the air pin box otherwise the Mor/ryde would be my choice due to the simplicity and price. The Mor/ryde is designed to eleminate back/forth chucking while the air pin boxes smooth out up/down movement and also seem to reduce chucking.
