I'm running the Bestop Highrock carrier on my YJ. Good up to 35 inch tire or 200lbs. Mounts to the roll bar through the tub and near the lower body mount. Also hinged to the tailgate so it opens and closes with it. Can keep any bumper you like since it doesn't mount to one. Very strong and doesn't rattle at all. Got mine for a little over $300.
