This is a big rollback, right now it has manual spool valves. What I've been thinking about doing is adding an electric section just to run the winch, maybe with a manual diverter valve to keep the manual section for a backup. I thought about doing the pull solenoid thing but it seemed like it might have reliability issues. It would be nice to convert the whole thing, but not necessary. I probably wouldn't mess with it at all except this thing has a 20,000lb winch w/ no freewheel.
