The RS9000's work well, but tend to get soft after 50K, which I guess isn't bad. The people who have the in-cab adjustment report that the air lines can be leaky and it's more of a pain than it's worth. Having the adjustor on the shock is not bad. Generally I only adjust them during a serious off-road trip when I didn't want the front end to dive into rocks. Now, with 60K on them, I just leave them on the firmest adjustment.

The adjusters can also freeze up if you don't adjust them for a long time. It's not hard to unfreeze them and add grease to prevent it from happening again. It just gets some rust in the adjustor.

Overall I like them and will probably replace them eventually.
