I know Black Panther was planning on making something, but then he fell off the earth.
I am not sure there is really much room behind the stock bumper to mount something like that.
You might be able to come up with something where as you remove the stock steel bumper and make a 2" receiver hitch that sticks out of the front of the bumper. You could then use something like the Warn xd9000i portable
the only bad thing I could think of that would be if you got in a wreck, the stock steel bumper wouldn't hold up, then, if the wreck was bad enough, you're out a bumper AND winch
it is possible, i measured once behind the factory bumper and there is plenty of room to mount a smaller housing winch like the ramsey rep 8.5......my fear would be as contenderv07 mentioned....damage in an accident.
