Avoid the hoses and the fancy in cab controller, I hear nothing but bad things about that in cab set up. The Ranchos are really good shocks, set them once by hand to 9 (max stiffness) and forget about it
I 'test' the Ranchos daily over the same stretch of road that killed a stock KYB aluminium shock with expansion chambers, The road has gotten worse over time, but the Ranchos continue to overcome the torture. Avoid the in in cab device.
BTW I've heard good things about the Billi's, but have not tested them.
