Off the top of my head, the western/fisher pro fro 2. Air flo makes a unit which dino (plowking35) has uses, the baby is the name of it i think. it's a 1/3 yard stainless spreader availible gas powered or electric. use the search function to find more.
Air Flo's unit is the MSS and would not work in a receiver without some interesting fabrication.
I would look into lightweight single stage poly hopper units. They will only be able to spread salt though unless you go with a Trynex.
I saw a Wrangler today with a Western uni-mount. Plow sure hangs out well in front of the bumper. I guess this is because the uni-mount frame is even with the bumper. Not like the old Jeep plow frames where everything was behind the stock mounted bumper.
I bought a Trynex 575 with the hitch mount for my Blazer last year. It would be perfect for the Wrangler. Do a search for "Trynex". There are a few discussions here about them with links to places to buy them.
