I have towed several Wranglers and CJs (and a Datsun pickup) with a Reese stiff-arm adjustable width towbar ($165 at Walmart the last time I looked) for many years. In spite of the doom and gloom from the telescoping arm aficionados, it has worked just fine for me, I even hook it up by myself!
Several years ago, I bought a Roadmaster telescoping towbar (6000 lb. capacity) to tow a Dodge 1500 pickup. Never did like that thing. When I got another Jeep, I went back to the Reese towbar.
It simply works for me.
