This Cornerstone has the Hadley SLS active air system. The suspension is able to make adjustments as you are rolling down the road. Mine started venting briefly around every 30 seconds. It would stop if I raised the chassis above ride height. Once you start rolling, it automatically reverts to standard ride and commences venting. There are 8 individual solenoids - one for inflate and deflate at each corner of the coach. I believe the driver's side front exhaust was malfunctioning. These solenoids can be replaced/rebuilt. Spartan elected to replace the entire manifold. The part was back-ordered for a month.

Here it is - I don't even want to think about what the list price for this thing is:

Is it possible that this is the same problem that Newmar Mountain Aire and Essex are having and just posted a recall on?

That is one complicated looking piece of equipment. I think that falls into "the more we have the more to break" category. If it was on my coach, it would be broke for sure

Just getting to complicated. Better have extended warranty to keep up with this stuff after 2 years.

I don't think so. I think the control module sends the signals to each of the 8 solenoids to tell them whether to inflate or exhaust. My problem was with one of the indvidual solenoid valves.

Roger that.

If it were on your coach, it probably would never have worked in the first place.
