Koni FSD Shocks
Would those members who have installed Koni FSD shocks on their Class C do it again? Or do you regret the decision. Thanks.

As I've stated before in these forums - I have absolute proof that the Koni FSD shocks in the rear of our Class C reduced the cracks/pothole pounding back there when traveling: Both our shower door gravity latch back there now stays latched, and the little plastic shelf on the back wall never has it's contents bounce out.
Of course maybe Bilsteins would have done the same - but nothing in the Bilstein literature states that they provide a damping rate that varies depending upon the quickness (frequency) of road surface change.
I really think that where the high frequency light damping mode of the Koni FSD shocks comes into it's own is on RVs that are really stiff springed relative to the motorhome's weight (which is our situation with a 24 foot Class C on the E450 chassis). In these situations a quick bump in the road does not need any shock's resistance added to the spring's resistance - so light or no shock damping is better for reducing the jolt.
Most RVs on the E350/3500 chassis and larger RVs on the E450/4500 chassis - will have a higher vehicle weight to spring stiffness ratio that is not going to transmit sharp jolts from the roadway into the vehicle nearly as much as a lower ratio will. I'm sure Bilsteins (and many other shock brands) will handle these situations well enough.
