Its like an amplifier circuit where a capacitor across the input prevents noise from entering the amp while a capacitor in the negative feedback loop serves to correct the problems that get by the input. JMO
As an electrical engineer, I appreciate how you worded this. I don't know for sure yet, but I am anticipating that I will need more then just the input capacitors.
Keep in mind that you already have some "feedback capacitance" in that you have at least +2.5 to +3.5 Degrees of Caster (assumed to be worst case) so adding more input prevention could do the trick. This appears to be the case in the experience of rcase13 earlier in this thread. On the other hand we have a recent thread where
DunnInn seemed to apply everything we have in our arsenal and still did not obtain satisfactory results.
Each of these RVs are dynamically unique and we can only hope to protect our investment and tame those combinations which are unacceptable to drive. The only reason I am so vocal about the +caster is because of my personal experience which is limited to one particular E450 with air bags. I wish we had more alignment reports and feed back like
Glenn Lawton provided so we could develop a wider picture of the real world.
I often think, what would we do without this users group which provides almost instantaneous information and ideas on how to live with the Ford E350/E450.
