Bob, We love the liberty,and have the Blue-Ox
braking system> I had to make a small support out of wood that was L shaped and sat on the drivers seat frame. This Is covered in carpet, and is held in place by the back handle, or push bar on the brake assest! Hope this helps, also have the Blue-OX tow bars and base plate.
Works good and lasts a long time, as we are very happy with this setup!! Tenn.Vol.
