You will get a lot of "opinions" on this, and many will be from a person with experience of the only pin box they have ever had on their first trailer. We have had several 5ers with different pin boxes. Some have had a rigid pin box. The current trailer had a Demco Glide Ride.
With the Demco, it reduces chucking but the links need replacing after about 20,000 to 30,000 miles. The link bushings wear and you start to get clunking when you start or stop, and it has some side play. We are using a Trailer Saver TS3 air ride hitch in the truck.
The best pin box we have had was a Mor/Ryde pin box. It helps to reduce chucking and is durable.
