I've just replaced my Orac with an Ozhitch.
For what it's worth, the cost to remove the Orac hitch on the camper and have the Ozhitch fitted was less than $150.
This included all grinding/welding and a coat of undercoat around the newly fitted Ozhitch.
Now to tape up and respray the drawer bar and it will look as if the Ozhitch has been there forever!
I doubt the "marriage" between the Orac and Ozhitch will work and will probably end up with there being a "divorce" sooner than later!
