I do not know of any, but with the rear hatch, i would think your mounting options are going to be limited. With the rear hatch going completely side to side you would have to opt for a horizontal mount. In that case, really any standard bumper could probably be adapted to do exactly what you want. Anything 1/8"+ would probably be able to carry a hilift on the bumper.
