RMS adjustable struts - noise, harshness?

I don't understand why it's so hard to find someone to work on torsion bar cars?? Many later model GM and Dodge trucks are torsion bars!! My 04 Ram is. Camber is camber,caster is caster,toe is toe!! A torsion bar is a spring.....all cars have some kind of spring!! If a tech can't deal with your cars....he better not be dealing with the millions of other torsion bar vehicles on the road!!
