Towing a 3 tonne caravan - WDH

In Aus, the breakaway cable also activates the trailet brakes, but you don't leave the trailer in the previous country

I think cross chains rated along with rated shackles is good practice, kind of seems logical. For the thought process of having a brake activating cable with a sacrificial carabiner to stop the trailer rear ending you, if braking, once hitch has failed then perhaps can have both. The cross chains being longer in length than the shorter cable?

Just thinking aloud.

Too different operations, whilst US and Aus attachments are a secondary coupling to prevent detachment of a towed trailer/caravan. With an overrun braking system it is the opposite, if detached from the tow hitch, the overrun cable pulls on the handbrake tight bringing the trailer to a stop, then snaps to permit separation of vehicle and parked trailer.
For those NA and Aus members who haven't seen a UK and EU breakaway cable

Actually, to clarify, the breakaway cable pulls out a pin which locks the trailer brakes. So when the cable snaps the trailer brakes are fully applied.
Somewhat archaic I guess.
