I found the Howard Power Centering system worked very well in a cross wind in areas with limited terrain. It was more problematic in hilly, gusty conditions. When on roads with an exaggerated crown, it did lessen the driving effort. However, I was using the Power Centering system on a much shorter coach with a very light front end and very heavy rear end so it was trying to make up for chassis shortcomings.
I doubt that I would find it nearly as helpful on a Newell. If a Newell isn't tracking well and is being blown all over the road, there is a problem that needs to be corrected.
