I towed several different Jeeps with a simple, inexpensive ($145), fixed arm adjustable width Reese 5000 lb. capacity towbar. It did exactly the same job as the bars that cost over a thousand dollars!
The last time I checked, Walmart had those towbars for $165. Harbor Freight has similar bars for under $100.
There will be scare stories about how terribly inconvenient such fixed-arm towbars are. For the doomsayers and naysayers that spread such stories, they are undoubtedly true. For me, I never found any truth to such stories.
NSA has the Ready Brake that works just fine with the fixed-arm towbar (or any towbar, for that matter).
