that because torsion axles have rubber rods, that you do not need shocks.
I for one disagree. WHY???
Yes the rubber rods in torsion axles absorb a lot of the bouncing from roadway bumps. BUT,
they do not absorb all of it.
Adding shocks, if you wish, fine tunes the road shock that the torsion axles do not completely eliminate. Even with shocks, are ALL the road shocks eliminated ?? Heck no, but they are reduced to a very acceptable level.
A friend of ours, who repairs Airstreams but is not a dealer, says he cannot tell the difference between shocks and no shocks. But, I dont believe he has ever ridden in the trailer, over the same bumpy road, with and without the shocks.
Again, opinions say no difference. Facts, like you get when you apply Physics, says, IT DOES MAKE A DIFFERENCE.
The torsion axles, INDEED, eliminate most of the shock, but not all of it, simply because rubber bounces. Adding the shocks, takes over where the rubber rods leave off, and further reduce the road shock that the trailer is subjected to.
On the other hand, why do auto manufacturers put shocks on EVERY motor vehicle ?? Simple answer, is because they reduce the movement of the motor vehicle that is subjected to the road shock. Every so often, a younger generation removes the shocks from a "hot rod". Watch it bounce and bounce, which they love, but it certainly is not comfort giving.
I am very sure that there will always be those that say NO to shocks, but since they had nothing to do with designing an Airstream, then their statements offer nothing more than an "opinion".
The funniest part, is why does Dexter install shock brackets on EVERY axle Airstream purchases from them, both for replacement and new product installation?
Airstream engineers are "not" always correct, BUT they indeed make very few errors, and they certainly would never, ever, continue an error for over 1/2 of a century.
No one, absolutely no one, has ever factually proven Airstream wrong using shocks, and never will !!!! Just my humble opinion, working with them bumping 50 years.
