After replacing the stock shock absorbers with Bilstein 5100 series shock absorbers which was a huge improvement, I decided to replace the steering damper. What difference does it make to our Thor Four Winds Chateau 23A Class C E350. It went from white knuckles, two hands on the wheel, to the comfortable feel of an SUV with one hand. Even in strong winds, the camper was much more manageable and required far fewer steering corrections. Highly recommended!
