Well I fixed mine.  Maybe it's just because it was on the coach and I am driven to see that everything just works as it should.

I now own almost a complete set of spares as I purchased a system from a Prevost.

I have had the experience of driving the coach with and without it for considerable time.  I like it.

One press on the big button and the steering is centered at that position.  Nice for a crowned roads and nice in winds.   Sure, I get where I am going with or without it.
One possible advantage not mentioned, but one that figures highly in the documentation, is the resistance to sudden steering movements that could be generated by an exploding steer tire.  Yeah, I don't want to test that one!

I had my steering cylinder rebuild by a company that does them regularly.  No leaks and no problems since.  The cylinder from the Prevost may be okay, who knows.   Just collecting dust in the basement right now.   Just my experience.  As they say YMMV

Russ, would you mind sharing the contact info on the company that rebuilt the steering cylinder?
