I changed the width on mine and have it attach to the S/R setup on the front, where the bolts go. Mine are 1/2" grade 8 bolts, so they're more than strong enough. A Class 2 hitch is more than enough for a Zuk, it's good for 3,500 lbs.
Mxnhid and I have towed a lot or Zuks with the shackles in the front by making up a plate that replaces the inner one on the shackle. The tow bar then attaches to this using another bolt, so it is easily removed. The plates would be easy to make, they're just 3 bolt holes in a triangle.
I also made my own wiring setup using some old Jeep lights, some bar stock, the front end off a Zuk bumper (I throw NOTHING away), and some wiring I found while dumpster diving. It attaches to the rear spare tire mount. I made it for about $10 or so, but that was for the split tubing and end connections. I have it setup so I can remove the lights but leave the mount in place.
I have flat towed for thousands of miles, usually a few hundred at a time. It's nice because I can take everything with me (like the spare complete axles, tranny, and transfer for EMWF III), but still have enough room. It's also nice to cruise towing at 80 mph in comfort.
