I have a Coromal Seka Pioneer XC 600 with a treg hitch behind a Landcruiser 80 series with a 2" lift and air bags inside the rear coils.

I want to replace it with a hitch-master DO35, easy done.

I now want to have an anti sway bay system as well when travelling down the black stuff as more of a safety item to ensure there are no rear end wobbles from trucks, etc.

I am not concerned about WDS as this is not an issue behind the cruiser.

Kind Regards

Bernie

Forgot to ask the Question, didn't I.

Has anyone got a setup like this and is easy to disconnect and remove when necessary or suggestions on the best setup?

Just curious about why you say the lack of a WDH is not an issue behind your cruiser, Bernie?

I would have thought a WDH would have priority over anti-sway devices if you are concerned about safety and stability with a fairly big van?

Hi Michael,

Between the weight of the cruiser being heavier than the van plus the air bags to raise the rear of the cruiser and with the heavier spring because of the lift, I can bring the van back to level from there.

Bernie,
The job of the weight distributing hitch is to distribute some of the tow ball load to the front wheels of the Cruiser and some more of it back to the wheels of the van. If the tow ball weight is heavy and the rear overhang is longish, relying on air bags to level up the Cruiser will raise both the front and the rear of the vehicle above the normal towing height and and leave it light on the front wheels.
It might look safe like that, but it sometimes isn't.

Yep OK, Keith sounds like that may happen.

This caravaning thing is new as we upgraded from a soft top camper trailer that followed along like a faithful dog everywhere we went but it was single axle and real heavy on the ball weight.

I didn't want to loose too much ground clearance at the hitch point, not that we will go real offroading like we did with the camper trailer (horses for courses) but some places we go need the extra height and ground clearance and that is where it will drag first more so than the rear of the van.

I need a WDH no problem and will that give me enough anti sway and what do you suggest is the system to use with the ability to easily remove it once I need offroad coupling to work?

Regards
Bernie

Bernie use a 3.5t Hyland coupling easy to hook up and trouble free. As far as WDH and sway bars are concerned I would first look at why the van is swaying and try and rectify it. I reckon anti sway devices are a last resort.

Sway control and weight distribution are two different problems. If you are going in and out of creek beds and over humps you'll have to take the spring bars off anyway, otherwise you can snap the gooseneck off as the rig goes down a dip. It's certainly happened before. The Gall Brothers snapped one off on Fraser Island.

There are a lot of lift bars on the market and some are easier to take on and off than others. I've only used the spring bars and they're horrible.

If there's a problem with sway on the road I'd be having a look at the way the van is loaded, the condition of the suspension bushes, tyre ratings and pressures and maybe thinking about installing some shock absorbers. Make sure the van is towing dead level and the ball weight is about 10% of the van, which should be OK for a twin axle van. If a twin axle van is towing nose up or nose down, it can make it away a bit.

I understand that trucks with a lift often experience more sway problems and that Kimberley have just put sway bars on their Karavans for this reason.

Years ago I bought a 16 ft van new from a dealer and it was all over the shop. Turns out that the tyres at max pressure were only rated to the unladen weight of the van. With ten ply light truck tyres and some shockers on, it was 100% better.

Good luck with it, Bernie

Thanks Keith,
Guess I was looking at a bolt easy fix and waste some more money.
