Kev,
Theres two points where it needs locking, Ive used a padlock through the bottom hole in the main removable pin. Then you have to lock the reciever onto the vehicle, this is on any system

Couple mate, I think they advertise on here, advised me they were developing one for the AT35. May be worth a call.

In the meantime I used a decent sized padlock which the locksmith advised and just drilled out the hole in the pin a touch more to make it fit.

I just use a Lockwood lock that fits in the original hole, plus a lockable hitch pin lock (bought from ExploreOz) for the tow hitch.

Yes, you need to be security conscious, but these systems will only deter the opportunist, not the determined professional thief.

I also carry a toughened steel chain and heavy duty toughened lock. I got it to put through one of the wheels of the CT and around the CT suspension. Bu putting the lock inside the wheel, it would be very difficult to get to to break or cut. Only problem is I rarely use it, but always use the locks on the hitch pin and AT35.
