UPDATE, well I installed Sumo springs to the rear as well and then took coach in to get alignment checked and it did change much. Technician made the slight adjustment and I’m good to go. I’ll have to say that the addition of the Sumo springs was well worth it. Coach runs down the interstate solid as a rock, of course I’ve installed hellwig sway bars front and rear and Bilsteins and the Safety Plus Steering control. Other than adding a Trac Bar I think there isn’t much more to do because it handles so great now.
