I'm assuming by "Supersteer unit" you mean the trim control, Russ, as SuperSteer is Henderson's brand and applies to many of their products. Comfort Ride is from Source Engineering in Washington or Eugene, OR, and operates similar to Henderson's SuperSteer Motion Control units but restricts air flow in only one direction (in) as opposed to the Motion Control's bi-directional valving.
I did not know, or forgot, that Henderson's sold the Comfort Ride devices, and am curious why you went with that as opposed to the SuperSteer ones, as I did.
It would appear that both Russ and I are happy with different but similar modifications, Jim, and on coaches similar to yours. You likely can't go wrong with either one.
