Nice Jeep, looks like a great platform to build from.
I think that the general concensus on winches in receivers is that the are great in theory, but the likely hood of getting hung somewhere where you can't get the winch into the receiver would outway the benefits of having a portable winch mount. The receivers often leave the winch several inches low, killing departure angle in that sort of a setup.... great in theory, not very practical in application. It's a shame though, that was the route I wanted to go too.
