    Reading this article – I bought a new RV that has tandem axle torsion suspension hard mount no walking beam. I have hauled it two times now each trip is a hard trip for how it pulls. When buying it, sales talked so highly of it. I should have known better. A company I deal with rents a heavy tandem axle tank trailer with torsions and they keep breaking the frames. Why would a RV manufacturer build one like this? I’ve tried all kinds of weight changes, set up scale, even tried loading it for a trip and it still walks everywhere while pulling. Just wish I would have read this before purchasing the unit.

    Very interesting discussion. Airstream uses torsion suspension, I’m not aware of them using a walking beam. Any knowlege of this issue wth Airsream trailers ?

      Yes, Many manufacturers use tandem torsions, and some of their customers have continual problems because of it. Most people get away with it. The engineering shows how and why it’s a bad idea, but the choice is yours. I also suggest this article with videos on our DIY site. It shows examples. Thanks for visiting.

    I live close to the manufacturing of most RVs and utility trailers.
    The biggest problem that I see, is the trailers are not level unloaded and they are worse under load. The torsion axle trailers that are level have few problems.
    The bigger problem that I have seen is the modified equalizers on leaf springs. They improve the rattle, but they can jam in an unequal position and make a big load difference between axles. Caution when you jack one axle up to change a tire.
    If loading changes during normal use, the air suspension is the only answer.
