TruSteer
I will be installing a new Tru Steer made by Blue Ox, on our 2007 Holiday Rambler Neptune. Really hope this stops the wander and unstable ride.... Bill

"Old Blue"......Sorry, but to start, the R4R chassis on that coach is the number one problem. No MATTER what you do to it, it will be a rough riding chassis. Our friends have the same coach. I started with adjusting their Ride Height and making sure the tire pressure was as low as it could go without causing tire damage. Then the shocks were replaced with Koni FSD's. This made the coach better, but not great.
In the past year some engineering has been taken on to solve the handling of particularly, the RR8R chassis, the chassis line above yours. Two things were found. The Shepard steering box was a large cause of the wandering ills of the coach. TRW makes a direct replacement that solves many issues. Second, the large "H" configuration of the Roadmaster chassis has always moved around, especially on the rear and caused wander issues. There are two people making "panhard" bars that tighten the rearend up like a tracbar does on a gasser. I don't know if anyone has created the "panhard" bars for the R4R chassis.
Lastly, I installed the TruCenter on my Diplomat and loved it. I didn't have wander issues on my coach, but the way that the TruCenter adjusts your steering for road crown and wind really makes a difference in how you feel at the end of the day. You're not worn out from making steering corrections for 6-8 hours. You'll like the improvement.
Make sure that when you install the TruCenter switch, that it's within reach of your hand so you can blindly reach down and tap it. I bought a momentary switch that matched my other Monaco switches and installed it next to the exhaust brake switch. You can't see them, but the Monaco panel next to your left leg has additional switch positions already precut into the panel. You have to remove it to see them from the underside and then cut them the rest of the way through.
