For an offroad Jeep that would see many long pulls definitely go with a Warn Winch. The 110V AC winches I've seen have all been very light duty. For an AC winch to be useful at heavy loads it would probably need at least 220v.
For very rare use on a vehicle the Smittybilt would probably be ok. Tow trucks using Hydraulics makes sense. Hydraulics on a vehicle that may never actually use the winch doesn't make sense. To use the Milemarker Hydraulic winch I would definitely use a second power steering pump. I would not connect the Milemarker to the factory hydraulics.
The top of the line 12k Smittybilt with wireless remote and synthetic line is $649. Still need the mount location, winch plate and recovery kit. Only connect to the top battery studs, never the side connection.
