With the bags inflated to just half of their capacity the hitch does not drop 2"., it does not drop at all maintaining the 24' unloaded height. Hence the air bags. I will continue to monitor and adjust {if/as necessary}.
I did notice the front was definitely lighter before the air bag install which is why I went that route. After two trips it was obvious an adjustment was needed. I also adjusted some of the interior loading in the coach to bring more weight forward. As I said I'll know more next week and will report back on what I learn.
