Yes it does look very similar.
I just already have the Blue Ox tow bar and had planned to purchase the Auto Stop to add to it. it will be much more expensive to have to purchase the ready stop tow bar and brake system, but that is what I will have to do next spring before I start towing again.
I did get a response from Blue Ox:
"It was becoming nearly impossible to install the autostops in the new vehicles because you have to run the cable though the engine compartment. When doing this there could only be 4 bends in the wire and no more than 2 inches of bend at each spot. The newer vehicles have some much more electronics, sensors etc. in them that it was no longer an option.
As for if Blue Ox will ever manufacture them, I'm not for sure but as of right now no, there isn't a new production date. I apologize."
I have been searching for someone who has left over stock of the Blue Ox brake units, but have not been able to locate one.
