Koni fsd rear shocks

Nice! I just bought my coach and noticed a harsh ride with the Bilsteins that were installed. Thought I give koni a shot before the wife wants a diesel with air suspension. I did notice that the dust covers were filthy on the Bilsteins that I took off...that's why I was curious if I should install them on the koni's. I too have the super steer track bar on the rear, along with air bags. I also just purchased the safe t plus. My goal is to be able to make the wife as comfortable as possible if I every need her to drive...which is a stretch goal.
