Why I’d never buy another Treg hitch

Going back a couple of decades ago, you’d rarely see different towing hitches. Today, there are more options for towing a trailer than you can poke a stick at. Traditionally, Treg and the normal ball hitches were all you’d see, and while the Treg was a great option when it first came out, I would never, ever get one again.

Originally, I loved the idea of them; quiet, fully articulating, robust and low maintenance. My first camper trailer had one, and I liked the idea so much that I purchased a brand new, genuine Treg hitch for my off road boat trailer.

These days, I hate Treg hitches, and I detest using them. They work OK on very light trailers, but anything over a few hundred kilograms when used off road is just a total nightmare.

What is a Treg hitch?

Starting with the basics, a Treg Hitch is an off road trailer coupling that is used instead of a 50mm ball coupling. It’s designed to be quieter and to articulate much further in the up and down and side to side motion.

Why are Treg Hitches no good?

The reason is really simple; they are a right pain in the backside to hitch, and unhitch. On level bitumen or gravel they are easy enough to work with, but the moment you are doing it on soft or uneven ground, guaranteed you are entering struggle territory. They have two very distinct shortfalls

Perfection required for hitching and unhitching

By design, you need to slide a poly block into an opening that has about 1.5mm clearance. 

This makes it awfully challenging when the ground is undulating, or soft as every time you move the vehicle the hitch height changes. If its not bang on, the block catches and flicks up or down, and you have to try again. Hooking on a Tregg hitch is a two person job, unless you get perfectly lucky.

There’s literally a couple of mm clearance between the poly block and the receiver, making it a nightmare

Pressure on the pin

The above however, is only part of my gripe. My real gripe is the fact that the pin can be an absolute nightmare to put in, and even more so to remove. The moment the trailer has any force on the pin, you are totally at the mercy of physics.

You have to struggle and sweat while pushing the trailer around and trying to free the pin, and it gets old real fast. This happens every time the trailer is pushing in a different direction to your 4WD (think basically every situation that isn’t perfectly level!)

I mentioned above that you get away with it with a lighter trailer, as its not hard to move it back and forth as required. Our boat trailer is under 500kg total, and is usually fine with it only rarely being a pain. Still though, I have had times where we’ve needed a couple of people to shove the trailer around while someone yanks the pin out.

Again, its a multiple person job and not one I particularly enjoy doing even on a light trailer. Imagine if your trailer was more than 2 tonne! A poly block hitch is simply not ideal as you have to line things up in three directions.

Trying to unhook on anything but flat ground isn’t much fun

Watch out for fakes

Another thing to be very wary of is fake Treg Trailer Hitches. This is completely asides from the issues above, but the fakes often fail within a couple of years, in a very bad way. With all of the Chinese Camper trailer and Hybrids coming in, you can guarantee that most don’t run the genuine Treg, Tregg or Trigg hitch blocks, and the materials have a bad habit of cracking and breaking away.

I’ve seen a significant number of new camper trailers that have come in running an imported poly block hitch, and they’ve failed within the first year. Not nice when you are in the middle of no where, and your hitch is welded on! If its bright red, there’s a good indication its not made here, and regardless of how hard it is to use, it could break at any time too.

A good indication of these is that they are often referred to as a Poly Block Tow Hitch, rather than a Treg or Trigg hitch.

What’s better than a Treg Hitch?

There are more hitches on the market now than I could even mention. The clear winner for me though, is the D035 hitch made by Cruise Master. It’s a super clever design, and is easy to hook and unhook no matter where you are. You don’t have to get it exact, and that applies to all three directions.

As long as you are within about 40mm, as you lower the hitch onto the receiver it self centres. The only orientation you really have to get somewhat correct is the distance you back under, as its easy enough to lean on the drawbar and move the trailer side to side a few mm if required.

These lock and unlock without binding up, have the same articulation, are silent, rated to 3500kg and overall make hitching and unhitching a total breeze. We got one on our new hybrid camper trailer – a Reconn R2, and have been very pleased with it.

Hitching and unhitching used to be a pain in the backside, with lots of frustration. These days, its a piece of cake!

McHitches have a good reputation overall, and there are some others on the market but I have seen a few failures and the DO35 seems to be the most common.

    I have a Treg on an off-road camper and I would not change it for all the tea in China. I do all the hitching my self backing onto the hitch is easy I back up to the hitch adjust the height and finish backing easy. It sounds like that the review is one-sided there have to be faults with the other brand as there is with the Treg and good points as well on both to be fair you should point the good and the bad of both to be fair, this will give me and other readers the ability to assess both hitches and not think it is only a commercial for the other hitch

  • Aaron Schubert December 23, 2019, 6:25 PM

    Hey Lyndsay,

    Do you use it on soft sand, or hitch it up on uneven terrain? Once the hitch is on, I found no difference between the two, but hitching and unhitching the DO35 eats it for breakfast.

    I’ve yet to find any downsides of the DO35, and still have a boat trailer with the treg. The review isn’t one sided, its just my experience, and based on that I’d never get another Treg. I still have my old camper trailer with a treg and even moving it around my place I find a nightmare. The DO35 is just so simple and easy, but that’s what happens as technology improves.

    It’s certainly not a commercial; I have nothing to do with Cruisemaster.

    Try one – you’ll love it. However, if you are happy with the Treg keep it; asides from the hitching and unhitching they are fine

    The McHitch automatic coupling of of course the clear winner, just back up and it hitches all by itself! Put the chains and cable on, done!

  • Aaron Schubert August 9, 2020, 1:06 PM

    Hey GI,

    I’ve heard a number of people recommend these. I’ve also heard of a few failures. The D035 seems far more robust, and is used most commonly across the bigger, and more ‘offroad’ style trailers. I do like the auto hook up idea though!

    All the best

    It’s disappointing to see a great Aussie product getting a bad review as the lead article when looking up Treg Hitch. I feel for the employees you have helped to make redundant with your comments. I personally find the hitch easy to use and well made. Thanks all you guys making them I appreciate your efforts.

  • Aaron Schubert August 18, 2020, 7:28 PM

    Hi Russell,

    I suppose you could say the same thing about robotic technology that has put thousands of people out of jobs. Technology advances, and with it comes better options. In my experience and opinion, the Australian made D035 runs rings around the Treg hitches, as very clearly expressed in the article.

    It’s not a bad product, or poorly made, just there are now better options out there. For real offroad use, hitching and unhitching was a nightmare for me, and I used to get so frustrated with the struggle. If you use it on road, or differently, perhaps you’ve had a difference experience. That’s just fine too.

    You’d be better off taking aim at those who’ve taken the Treg hitch, and blatantly copied it and had it manufactured elsewhere. They are the real people putting Aussies out of jobs.

    All the best

    I don’t see Aaron’s write-up on the Tregg hitching problem as a bad review. I agree with him. They are good, its just that it can be a bastard to hitch-up or un-hitch on uneven ground. Get bogged at an angle & try unhooking it!. For use on light trailers &/or level firm ground they’re good. Just off-road can be tediously painful.

  • Aaron Schubert August 31, 2020, 4:24 PM

    Cheers Ded,

    Can’t please everyone. Your summary is exactly what I was implying.

    I have a camper trailer with a Treg hitch and agree with AAron about the difficulty of hitching/unhitching on sand. Ever tried to move 1 1500 kg load in sand on its jockey wheel? Well try that, especially if there is a root in the way. More divorce material than reverse parking a caravan.
    No problem with it on firm flat surfaces.

  • Aaron Schubert September 5, 2020, 7:32 PM

    Hey John,

    Yep, once you’ve experienced the frustration you start looking for alternatives. The number of times I’d be grumbling away trying to hook our old camper trailer up was entertaining, to say the least.

    Have a mac hitch , release handle has a very slight bend in it and not able to straighten it as the tolerances are way to small so in the bin it goes , Polly block cracked in half ,dangerous to hold with hand when on soft sand trying ti line it up , easy to lose fingers , most of the new generation couplings are over rated and over priced and if there is any wear in the unit very expensive to replace parts .

  • Aaron Schubert October 3, 2020, 11:53 AM

    Hey Peter,

    Get a DO35. Nothing to bend, simple design and rock solid. There’s a reason most of the new, big name brands use them

    All the best

    Have a 3000kg off rd van. Treg was a pain off rd. Fitted. D4.5 . SHMBO loves it so thats all the proof l need plus the 40000 kl we have travelled off rd with the D4.5

  • Aaron Schubert December 21, 2020, 6:30 PM

    Hey Peter,

    I’m assuming you mean the DO45? I’m glad you are happy with it too; they are a great unit

    All the best

  • Ken Mills March 3, 2021, 2:33 PM

    I agree completely. I have a Tregg on a Supreme Getaway off road caravan, approximately 1650kg. If you are not dead level it is unbelievably difficult to unhitch. I have had it for 6 years and hate the damm thing. As I write I am in Walpole on a very angled site which caused me great grief. Hitching it up is a bit easier as my Toyota Fortuner has a great backing camera.

    Does anyone know do a conversion to a ball hitch?

  • Aaron Schubert March 3, 2021, 4:40 PM

    Hey Ken,

    Yep, mine drives me nuts, and I still have one on the boat trailer. If you aren’t using it off road, you could just go for a normal ball hitch. Alternatively, Alko do an off road ball coupling, which fits a normal 50mm ball.

    Seriously look at the DO35 though, they are a great bit of kit


  • Chris July 15, 2021, 6:37 PM

    I have to make comment on ALL THE NEGATIVE comments on the Treg hitch. I have been using these for some 50 + years, and I cannot recommend them highly enough. They are NOT that difficult to hitch up! I can hitch up in any situation by MYSELF. The users who winge about these hitches, in my opinion, will complain about anything that may present a small challenge. They have been used since mid 1950s and were the original hitch supplied by the Furness Caravan company in South Australia. SO, they cannot be such a pain in the arse as stated. Grow up and get a life! PS, the pins are easy to fir and remove, if you use your nouse!

  • Aaron Schubert July 15, 2021, 6:53 PM

    HI Chris,

    I’m glad you are happy with your Treg hitches. We were not. Have you tried a DO35 hitch, or something a bit more modern?

    All the best

  • Shane July 24, 2021, 4:58 PM

    Quick comment on the need for two people to hook up a Tregg hitch.
    Simple solution from an old construction worker.
    Use a “fox wedge”.
    I simply put the wedge in to keep the poly block level then back up.
    A reversing camera helps.
    No way I would be happy with someone holding the block level while I back up!!

  • Aaron Schubert July 26, 2021, 7:42 PM

    Hey Shane,

    Cheers for the comment. A wedge would work, but you still need a second person to adjust the height as you back in, and if its on soft material and you slip a wheel, it all changes anyway.

    I certainly wouldn’t have anyone holding the block straight either; hands and fingers clear at all times.

    There’s a tiny tolerance with these tow hitches, and other units on the market are much more forgiving when it comes to hooking up

    All the best

  • Keith Higgins August 12, 2021, 10:02 AM

    For those who get frustrated in trying to line up the treg coupling, I use a bit of tape across the top of the block to keep aligned, check your height and then you just reverse as you would any other trailer. Hope this helps.

  • Aaron Schubert August 12, 2021, 7:27 PM

    Hey Keith,

    Do you replace the tape each time you hook up? We normally just use two people, and take it easy and slow.

    All the best

  • Bruce September 12, 2021, 4:13 PM

    I had a 3 ton treg hitch copy on my off-road camper trailer for about 4 years. It worked well and I had no problems hitching or unhitching. On my last trip to Cape York the bloody thing failed, and started spitting and small chunks started falling off in 2 or 3 days. Caught short now, I found a replacement AL-KO 3.5 ton. This seems to work well now, but it’s early days still. BTW my trailer is 1.5 tons max with ball weight of about 140Kg.

  • Aaron Schubert September 12, 2021, 7:35 PM

    Hey Bruce,

    The copies are notorious for failing, but sounds like you had a decent run out of it. Let me know how you go with the new AL-KO; I haven’t heard anything bad about these yet.

    All the best

  • Sara Johnson September 27, 2021, 4:35 PM

    Treg Hitch on 1250kg Cub Spacematic Drover was a nightmare to hook up and disconnect. If you like the Treg then fine but all the points raised by the author are accurate in my experience. I have moved to the AL-KO offroad ball coupling and have been very impressed. Took the Mt Lindsay Road and managed to make the journey without any issues. The benefit of the 50mm ball is that I can hook up to my boat and my 6×4 trailer all with the 1 coupling. Just my 2 bobs.

  • Aaron Schubert September 27, 2021, 5:51 PM

    Hey Sara,

    Cheers for the comment, and your thoughts. I’ve heard some good things about the AL-Ko hitch; it will be interesting to see how they go in terms of market share. Does it make any noise when travelling?

    All the best
