Rancho "remote" adjust debug
My "new to me" F-350 Dually came to me with 4 Rancho 9000 shocks and an odd "remote" setup for controlling them. I say odd, because it was some aftermarket (non-Rancho) digital controller plus a Fi...

Suggestion: Post a wanted ad on craigs and other truck and rv forums requesting the take off manual knobs from Rancho 9000 owners who have added any type of in-cab controller (like "MyRide" etc)
Then, with the manual knobs in hand, unscrew the two allen bolts at every shock, and install the manual knobs. When you disconnect the air lines at the shock body, any air pressure applied to the valving piston will be released to atmosphere, so you can set your knobs to the 12 noon position, fully retracted.
Having converted the shocks back to manual control, you can
1. Determine that the shock absorbers themselves actually dampen your spring bounce, and
2. Determine the optimal normal setting for your shocks by experimentation.
That having all been done, you can then see about your aftermarket air actuation system. I've had Rancho 9000 shocks for 12 years on my current tow vehicle, and after making occasional adjustments, I have not found that I necessarily "needed" an in cab control system, with all of it's vulnerabilities to failure.
