Thread: Trailer Couplings.

Hi mate and welcome to D4 ownership.

We have used a treg hitch on our camper trailer for many years. There is no issue with strength but they can be difficult to get aligned and hitched if the trailer is heavy and/or on sandy ground. A reversing camera and height adjustable suspension covers this short coming a fair bit though. There are other offroad hitches around that are easier to align but I'll leave it to others to compare these.

Cheers
Chris

I use a Tregg on the Kimberley Kamper. Tug is a Disco 2. No issues. I find it easy to align and hitch ... but, I always put a small sheet of form ply down under the jockey wheel (2ft x 1ft). I place it at 90deg to the Kamper, and face the jockey wheel the same way. To hitch, just back up with the tug hitch beside the Kamper hitch, and pull the Kamper poly block into the tug hitch sideways. So easy, the wife can accomplish the pull and insert pin while I'm still in the drivers seat !

The Disco has SLS so getting the heights right is easy. Raise D2 rear, wind Kamper up to match height, pull sideways and insert the hitch pin.

There may be / are better hitches on the market, but the Kimberley came with the Tregg, and since we have no issues with it, it's stayed ... I still hear a lot of people complain how hard they are to hitch up ... ???

That's a great solution to hitching a Tregg Kev, I wonder why no one else thought of that.

D4DasMar - welcome to the forum, and on your purchase. . I've never seen nor heard of a Tregg poly block coupling having any issues while being used - the biggest complaint is the hitching of them, which Fluids has an easy solution for, so I would use it as you get it and see how you find it. They are strong, and quiet - there should be no need to go running out to buy something else.

Just be wary that you have a genuine Tregg/Trig hitch. I've been reading a few threads now on myswag where the Chinese import campers are coming with fake tregg hitches in some cases (or rather copies). I've seen a report of one failure (of the copy) so it may be a bit of a beat up but keep in the back of you mind if its not the aussie made version.

It seems like a default option to swap out the hitch and bearings (or at least put more grease in them) on the import campers once owners have taken delivery.

I'm interested to hear others opinions on what couplings they use too as I'm looking at trailers now myself.

Geez, hadn't seen that Stu, thanks for posting. Based on that, it sure would pay to check the hitch is genuine.

If we're going to talk about others, I'm looking at replacing the standard towball for my caravan with a Mchitch. They do a couple of different types - a drop on and automatic style ranging from 2 tonne to 6.5 tonne - McHitch Trailer Couplings. My van has a standard old school hydraulic override brakes and they do a direct replacement for that too - McHitch Trailer Couplings

Check out the videos to see how they work. Both styles have double security and the drop on style is physically screwed to the post as well as pinned so they can never come apart.

It's an interesting question given the wide choice of off-road hitches now available. No issues with a real Tregg we have used them on all our OR campers but I have fitted an Oz Hitch, https://www.ozhitch.com to do some comparisons against the Tregg. With a reversing camera it is pretty easy no matter which hitch you select. We have 3x Ultimate campers which are strong and light but if you are heading above type of weight and down-ball weight something different may be more suitable

After a year of testing with our D4 we are about to swap the hitch for a DO35 for the simple reason that we feel the Oz Hitch design moves the camper connection around 130mm from the hole in the tongue. Whilst nothing untoward has occurred I feel that with all the off bitumen and off road towing we do there is a bit too much leverage too far back which may and I repeat may be making the self levelling work a little harder then necessary.

Overall happy with the Oz Hitch and we have had varying experiences with the DO35 in dusty conditions but hopefully the newer design has resolved that matter

Thank you all for you replies and suggestions. Fluids, that sounds like a great technique that I'll take on board so that I can give the unit a fair crack.

Stuee, thanks for the warning, as it turns out the camper is from china so chances are the block is a cheap knock off which I will investigate. The rest of the camper looks OK and comes with a 5 year warranty so hopefully any problems surface in that time.

Cheers to all,

Daz.

Both the McHitch and the OzHitch move the centre of the towbar reaction significantly further away from the car than a standard ball, DO35 or Tregg hitch. I had a McHitch on my previous camper trailer and the tongue bent about 20 degrees on the Reynolds River track into Litchfield National Park near Darwin. I had to put a really heavy duty Hayman Reese adjustable hitch onto the D4 in Darwin to continue our trip.


I have a Tregg Hitch on my new Kimberley Karavan and don't find it any problem. With a single axle trailer it is easy to move the trailer sideways to get the holes to line up. Not so good on a tandem axle though. If I did replace it with anything, I would go for a DO35 to keep the trailer reaction at the correct point on the towbar.
