As as follow up to the previous post, I bought a Secure-A-Hitch (actually the whole tongue with the locking mechanism fitted) from Rock Tamer at the Caulfield show a few weeks ago. The standard Mitzibishi tongue was very loose in the receiver (mostly due to the pin holes having enlarged) and the Secure-A-Hitch works well, by locking the tongue into the receiver. As usual, no association, just a satisfied customer.
