I had Steer Safe installed on my 1985 Class C, at the factory in Deming, NM back in 1987 - made a 100% improvement. Next when we got our 1995 Holiday Rambler Class A, we had it added after driving it on two trips. It worked great again a 100% improvement. We have a diesel Class A and have not needed it. But our son just bought a new Fleetwood Flair 36 foot Class A. He said driving it home from the dealer, around 800 miles he said it was a hand full, remembering I had always talked about the handling of our motorhomes, he asked me and I told him how well Steer Safe worked foe me. He did some research and will have Steer Safe installed next week. I will let you know of his experience. Also it is a really nice company to work with.
