I used the Trailair Rotoflex on my previous SOB 5th wheel and have the Morryde on my Montana. I would say they are the same. I towed the SOB without the Trailair and with and it really made a difference. I never towed the Montana without the Morryde.

Since I have a pullrite superglide the Morryde is restricted to only front and back movement which is like the Rotaflex.

Different suspension types i.e. leaf springs vs IS as well as location of water tanks and whether they are full or empty all affect the issue of chucking and the solution.
