I have used the Steer Safe on a 36'Freightliner chassis Meridian and it helped with the wind and truck passing issues quite a bit. When we went for our 42' coach (again, Freightliner), I installed a TruCenter active steering stabilizer that can also re-center the steering to accommodate cross winds, road camber, etc. This really works great and makes driving a much more relaxed experience. There is no impact from passing trucks, cross winds, etc. and you can instantly adjust the centering to accommodate changing conditions.
Best wishes.
