I've had a Richmond Loc-Rite Locker in the rear of my 88 Ranger for 10 years, works just great, its automatic, no air lines, wires or compressors. I'd like to put one in the front but its a IFS, not worth it.
Harbor Freight has a 12K winch for 300 bucks, I have one, works great, I switched out the steel cable for synthetic, much easier to use, stronger and lighter.
