Thread: Trailer Couplings.

I have done lots of KLM's with a McHitch Uniglide Trailer Coupling

The attached image shows how its hooked up to the D4. I am very happy with this setup.

Hello D4DasMar,

I had a Tregg Hitch on my previous Campervan and it worked well with the Discovery.
I did have one complaint with the Tregg Hitch and the Discovery but did not worry me enough to change hitches.
The issue is when you unhitch. When you lower down the jockey wheel to take the weight of the camper it also takes the weight off the rear of the Disco. This then makes the Disco rise in height. When it rises enough (which is not very much) the suspension will automatically lower. Because the Tregg Hitch is a block this will transfer weight from the Disco to the Jockey Wheel and you will have a unknown amount of weight on the Jockey Wheel. The only way to stop the lowering of the suspension height is to remove fuses.

Once I became aware of this I would do the following:
I would lower down the Jockey Wheel and start to take the weight of the campervan slowly.
Once I hear and/or see the height changing I would quickly raise the Jockey Wheel to roughly the change in height.
This would then stop the weight of the Disco being transferred to the Jockey Wheel.

I now have a DO35 on the caravan and when the Disco automatically lowers the DO35 Pin just drops out of the DO35 Hitch.

NTB I leave a door open when hitching and unhitching and it stops any undue suspension changes on my set up. I use the same technique for the boat and caravan after being caught on the first disconnect .

Hello Dudela,

I tried every combination of open and closed side and rear doors, engine running and stopped. No matter what I did I could not stop the suspension from moving to adjust its current height automatically.

I wonder if they have changed this in the later models.
I see you have a 2015 compared to my 2011.
That would be a good change.

I'm with you. I have used a Hitch Ezy for the last 5 years on two different caravan and wouldn't use anything else. It's a very clever bit of gear designed by a very smart guy. Non believers should take a serious look.

I added cabin controlled elec. braking to our camper as, even though not a legal requirement, I can lessen the effect of the trailer trying to push the rear of the D1 around on extreme descents. It is also less strain on the D1 brakes all round & for the money, I'm more than happy with it & feel a lot more secure with the rig overall.

So are you saying your camper fully loaded weighs less than 750kg? Or am I reading something wrong?

The hitch ezy looks like it needs to be wound up a long way on the jockey wheel. Has anyone had issues with this? There have been a couple of times I've ended up unhitching the van on uneven ground where I've just about run out length on my jockey wheel on a standard 50mm ball. This looks like it needs a lot more height than the DO35, but I could be wrong.

Using a D035 on our tvan and no problems so far, despite some dusty dirt roads. Only problem is the fragile dust cup. If you do get a D035 might be worth using lanotec or silicon spray to weatherproof.
