I’m trying to wrap my head around all of the possibilities.
I understand the HCV theory of operation under normal conditions and installation.
I question the use of the sway bar as the “anchor” for the HCV control rod. As far as I can tell the only other option to the sway bar is installing the HCV in the wheel well at the upper air bag structure and utilizing the upper A arm as a control rod mounting point. Then the question is installing two HCV’s and splitting the steer air bags up???
Yesterday I returned from my trip to Little Rock. As I departed the RV park I had to raise the coach due to a horrible parking lot exit. I pulled into the roadway center lane and lowered the coach until I was satisfied all air was out of all air bags. I then let the suspension raise to Travel Height and started my journey home.
I was content with the way the coach was driving. After an hour or so I stopped at a rest stop to take a break. The rest stop was packed and I had to park on an upward incline. I was there 20 minutes or so before I departed.
Once back on the highway the coach drove differently. Poorly, like I’ve described before. As soon as I could I pulled off the highway and reset the suspension again by lowering and allowing it to come up to Travel Height.
I believe it did drive better after the “reset” but I also experienced windy conditions.
The entire trip I never raised the coach with the Valid panel. Only lower and Travel Height.
