What's preventing a person from installing and wiring a winch?
You will need a fat wire to the battery - need to check if the one in the engine compartment is fat enough, or you may extend the positive lead from the starter terminal.
Negative is also easy enough - to the forward-most earth point on the frame, or all the way to the battery if desired.
Personally, I don't like hard-wired winches without any means of disconnecting them - out of old habit of expecting the insulation to chaff on something. So you may need either a
fat switch like this, or a relay carrying out the same function.
There's plenty of room inside a factory bumper for a remote-solenoid-type standard planetary winch, up to 12k lbs. You'd have to make your mounts to the frame - practically your own winch tray, cut the opening in the bumper for the fairlead, run the wire outside, and do whatever needs to be done with the solenoid block. Relocating the solenoid block will most likely need fabrication of three or four fat cables from the solenoids to the winch motor, and whatever else needed to control the solenoids. Wirelessly-controlled solenoid blocks are convenient, at the expense of some lost reliability.
