That one would do, if I could find a better price.
The least expensive one on ebay is $479!

That one is only 5000 lb capacity. I already have one with that capacity. If I could find a similar bar with 6000 lb or more capacity, it would be perfect.

That one has potential, but I would rather have a ball hitch, and use the Ready Brake ball mount. Just one of my little idiosyncrasies.
