You can do it for around $350-400 if ya know what your looking for and can look in the right places.
That being said, an interesting side effect of anybody thinking full hydro for on road usage. Mine and that is all I can speak for, I am constantly turning left on the road. I attribute this to the crown of the road and the fact that the orbitrol allows a "Bypass" when centered causing a constant counterclockwise rotation of the steering wheel to counter the crown. 15 miles I made an approx. 5 rotations of the steering wheel. Kinda weird and just thought I'd throw that out there.

Only problem I ran into was the driver side tire hit the steering box when turning right. A set of dually hubs fixed it, but made steering a problem. I think the combination of huge tires with no air and the crazy scrub radius is a little much for the pump/box/ram.
