I have just replaced by drop-on McHitch with a McHitch Auto Autoupler to make it easier to hitch up on my own.
I was planning to put the old one on Gumtree when we get back from holidays in a few weeks time.
It is rated at 3.5 tonne, has no over-ride facility and comes with a handbrake handle and bracket. It is at least six years old as I bought it early in my build, but has travelled less than 500km. It could do with a paint touchup after lying around the workshop for long.
It's yours for free if you are happy to either pick it up for pay for freight ex Sydney.
