That debate is somewhat true, but it does have an error.
Yes, no question, that torsion axles absorb most of the roadway shock.
But, it does not absorb all of it.
Therefore adding the correct shocks, helps to further reduce the impact to the trailer.
However, in fairness, while the Airstream shock further reduces shock, it does not eliminate all of it.
So, bottom line is that using the Airstream shock, further helps to create a softer ride as best possible with current technology.
Is that necessary ? Most people think so.
Then there are some that feel balancing the running gear is a waste of money, because the "torsion axle" absorbs that vibration as well.
History has clearly proved that an Airstream trailer must have a soft ride, and as soft as possible, because in part of it's "monocoque type construction. Violating that results in repairs that over time become very expensive.
Top, in your years of Airstream repair, I'm sure you have observed that all to many times.
So today, what appears to be the best for Airstreams running gear ?
Torsion axles, equipped with shock absorbers and Centramatic balancers appear to be the best that can be done. While still not perfect, that combination does a pretty good job, creating that soft necessary ride.
But again, to each his own, as it's the owners call as what and how their Airstream is treated.
As servicing people, we both know the difference between caring and abuse of the trailer.
