If you have done research into caravan couplings you will quickly discover that there are endless possibilities.Before we go into these options we first just want to get everyone back to basics. A coupling body is the section that is attached to the ‘A’ frame of the trailer. It forms a socket for the tow ball and provides the necessary pivot point between the trailer and the towing vehicle.

The coupling best suited for you will depend on the type of road your caravan will travel on and the type of caravan you own.  To make things simple we have highlighted the most popular coupling bodies and described what they are best utilized for.

Firstly, if you plan on keeping things really simple and you don’t have any desire to going off-roading or require any extra articulation for your caravan, then we suggest you stay with the standard 50mm coupling.

If this isn’t you, and you are looking for some off-road adventure then here are some other choices:

Treg & Trigg Couplings

The Treg and Trigg couplings forged the way years ago as the off-road coupling. This well-known poly-block couplings were one of the early versions that provided universal movement in most directions.

Hyland Coupling

The Hyland coupling took the universal rotation system and applied it to the standard 50mm towball. This means that no special pin is required. This has became a very popular coupling and is commonly seen on off-road caravans.

Vehicle Components D035

This coupling has become very popular. It is a refined version of many earlier off-road couplings and is exceptionally easy to use. Whilst it uses a pin type system it’s like a towball where the pin is tapered naturally guiding the coupling onto the pin (ie. no awkward line up required!). Vehicle Components run fairly rigorous testing on their products and have continuing evolved their coupling design through the years.


This is a fairly sophisticated coupling best for the serious off-roader. This coupling has several features and is extremely robust. While it is a bit more expensive than the other couplings, it does comes with a secondary locking system, bushes to prevent towing noise and also seals to prevent water and dust getting in.

McHitch & OZhitch

Both these couplings use a universal joint to handle the vertical and horizontal movements. It’s available in various load ratings and configurations. The OZhitch also has a fairly easy drop-in type hook up system which makes connection nice and quick.
