I have had a camper trailer with one and have got a caravan with one never had any problems with them but they are a pain in the ass to hook up on your own.

Bros,
We had one on our camper but replaced it with an ORAC. The treg sits quite high and we could not open one rear door on the GQ (in fairness, friends have an 80 series with one and dont have any issues). Also, it does not give full articulation, (not much better than the 50mm ball). For these reasons we replaced it with the ORAC. (I have a Treg for sale if anyone is interested !!!)

Hi Cameron

What do you mean by "Also, it does not give full articulation, (not much better than the 50mm ball). "

I have owned trailers with both and I would rate the treg coupling extremely highly in comparison to a 50mm ball for articulation. I would go as far as to say that it would be damb near impossible for you to exceed it's capabilities whilst attached to your GQ.

Treg gives full 360 deg radialy, as far as your vehicle will permit horizontally and the same for verticle plane and or a mix of either and all. Perhaps I misunderstood your comment.

cheers

Foss.

Lack of Articulation? A witnessed a mates CT roll onto its top on gunshot creek on the cape. Just handwinched it back over and kept driving. We did the whole OTL minus the last 2-3 creeks fine, up and back. Did the GRR, Bungle Bungles etc and have never felt the Treg limit articulation. Sure there may be other couplings that are just as good (or easier to connect) but I'm yet to see the articulation of the Treg be a limitation

G'day Foss,

Re you your comment on being virtually impossible to exceed the Treg capabilities - it can be done, and is done by the Orac.

Treg is a great coupling - nobody is arguing that point.

Orac has a better horizontal articulation [90º above and below the horizontal], though whether that is effectively usable is a moot point.

I had an Orac on my offroader and could not fault it. I would have possibly been just as happy with the Treg

Both great products

Go here for a web page which points out the comparison between the two.

Foss,
I'll give you 360 rotation (not that I would like to put this one to the test whilst attached to the vehicle !!!), but if you hold the treg horizontal, rotate to about 50-60deg, then rotate vetically, the housings foul. I did not like this because there have been times when I have needed to jacknife the trailer over uneven ground, and I thought there was possibility to damage the coupling, that is why we went for the ORAC.

Bro has a Treg on his Camp-O-Matic and is quite happy.

We have an Orac on our CT. I reckon both are a hugh pain in the arse to hook up in the scrub, esp. sand. I think the Treg may be a tad easier... but can't say for sure as I've never actually had to use one. Just appear to be easier as you can load the weight vertically on the little sucker.

I agree the Orac has limitless travel ... but if you have to go that far I don't think you'll be worried about the bloody trailer.You're only as old as she feels

I use my Treg behind the G60 and the Commodore( I have 16" and 14" trailer wheels) and have no complaints. I have had the trailer in Extreme 4x4 situations and the Treg works well. My trailer is not so heavy(under 500kg) and hooking up is not a problem. I am happy with the Treg.

Rosco,
Like everything else in life...there is an Easy way to do things and a Difficult way. I normally choose the Easy way which is to use your jockey wheel on the trailer to position the coupling. I used to have muscles but now they have turned to something else:-)))

I've been using a Treg hitch behind a Ford Raider and now a Disco and have never had a problem.
I'd hate to have to hook it up by myself without the aid of a jockey wheel though.

I use a Treg on the CP and wouldn't have it any other way. Like Willem, use the jockey wheel and make life easy for yourself. In fact my son has set up his work trailers (He is a concretor) with treg after having them come adrift with a ball on some sites he has to access

Bros,
I have an Orac coupling with the horizontal pin, this is a tad challenging to couple up in the bush, a mate of mine has a Treg coupling with the vertical pin and this is easier or so he tells me. Luckily I have a drawer on my O'brien camper trailer that counter balances the trailer so it's easier to turn in sand. I find putting a little bit of silicon grease helps the pin slide in a little easier if that helps. The red dust always attracts the grease so I only use a little bit. Keep the shiny side up

Guys,
I've been having internet problems, hopefully it's all been resolved now. I got the Patrol at the begining of November, very pleased with it, I've had a slight fuel leak which the dealership has had two attempts to fix, suspect it may be going back for a third go, I'll wait and see.
Got NEL (Never Ending Loan) at what I believe was a reasonable cost, straight enough, not loads of extras, no dents a bit of red dust but it's all underneath nothing in the door panels or anywhere like that, I'm pleased. the gearbox appears to have had fifth gear done by the gasket sealant on the housings, turbo EGR valve and other bits all appear good. Bit wary of all the electronic engine conrols after the GQ's simplicity, I suppose confidence will grow over time if it's reliable, i like the one drive belt idea instead of the four belts, makes the changing a lot easier. The camper trailer sits level now something it didn't do with the GQ. I've lifted it and put some radios in, plus a compressor, roller _Affordable_Storage_Drawers.aspx and dual batteries, that could well be it for now, we'll see.
Thanks for asking. Keep the shiny side up

Martyn,

The funny thing about the drive belt is that my old G60 has only one belt as well. Doesn't have to drive as many accessories though :-)

On a personal note... I was reading a post in the archives where you said that you came to Oz 13 years ago. Did you come from RSA? as your EO post motto is a favourite of that country. I am from there originally.

If you wish you may contact me by email.... willem@kempen.id.au

Bros,
My Kimberley Kamper has a Treg and it works superbly, just as some of the above comments have remarked.
I'm quite new to the reversing game but found it very easy to couple up, even if by myself, by using the jockey wheel to get the height approximately right and the Cruiser's mirrors to centre the LC as I reversed. Usually only 2 re-checks after that and including fine-tuning the jockey wheel height, and more often than not the LC fitted over the treg like a glove. Actually got quite proud of my efforts in the end.

Bros,
Have you considered the Hyland hitch ?
Fully (fore & aft, as well as 360deg. lateral) articulating 50mm Ball off-road coupling... I repeat, FULLY ARTICULATING 50mm Ball hitch..
This is what I specified on my custom-made (tandem hard-floor) off-road camper trailer.. Took delivery a week ago, & will be "testing" before Xmas...
I know at least a couple of people who have "upgraded" from a Treg to the aforementioned Hyland hitch...

Is this the one with the ball cup mounted on a pivot at the centreline crossways ?? I have seen one of these and thought it looked like a great idea, but am unsure of using it with mechanical override braking - ie does the ball cup rotate forward on the ball when braking ?? Are they adr approved ? Thanks ED.CMoo... everyone knows what a Jackaroo looks like :-)

Guys, the Hyland hitch is the way to go. Know of 2 others with these and think they are great. Much easier to use than the Tregg or Orac and you retain full articulation.
Bradley, I have a collar on mine which prevents the mechanical overide from working, just rely on the electrics.

G;'day Bradley,
Yep, that's the one... The ball cup on the Hyland hitch has a "skirt" which extends over the flange at the base of the ball, restricting any tendency for the cup to rotate on the ball... Also, the pivot is slightly below the centre of the ball, so I can see no problems whatsoever with over-ride braking... Indeed, I have mechanical over-ride (disc) brakes on my trailer, and I'm very pleased with the way it all works...
Are they ADR approved??.. To be honest, I didn't think to ask, though FWIW they do have their load ratings stamped on them.. I do know that Kedron Caravans (Brisbane) have been using them on their off-road vans, and there are a couple of trailer mfrs. in the Bris./ Sunshine Coast area using them as well, so I would assume that they would have to be "complianced"...

As for noise (mentioned by a couple of folk), I have eliminated the "rattle" from my ARB (Hayman Reese type) hitch, and with the ball/cup clearance properly adjusted on the Hyland hitch, I assure you that there is not a sound coming from the hitch area of my vehicle...

IMHO, the Hyland hitch is without doubt the best off-road trailer coupling on the market.. That's why I got one!.. (others' opinions may differ, of course, & that's ok with me)...

I have the Treg. Would never go back to ball. Yes, even with jockey wheel it can be a fiddle to connect (esp when trailer fully laden). Quiet, smooth, strong, excellent articulation (even allows trailer to barrel roll - just remember to untwist the safety chain and wiring). Big plus is rear doors of both Disco and Lexus open unimpeded.Bob

I think that both are very good hitches and necessary with any vehicle/trailer combination that intend venturing off-road.

We have an ORAC on our all aluminium hard floor camper. We opted for the ORAC because of space limitations between the rear mounted spare and the towbar. The ORAC is pinned from the side vs the TREG which pins from the top.

We have overcome the 'connecting up' problem by NOT using the ORAC pin, but disconnecting at the Hayman Reese receiver hitch. This makes connecting it back together much easier, as it will self centre.
