Re: The Towing thread

Good work mate. I was worried that you might have to remove the bumper again.

Yeah you can rarely disconnect one of the ultrasonic sensors from these systems. To stop the beeping from driving you nuts when reversing, you can just turn off ParkSense from the dash. The only downside is that it turns off the front too.

Happy towing!

Cheers,
Steve

Bigskiddy is on a distinguished road
On a trip at the moment towing the caravan. Last night did a quick stop. Lowered the quadra lift to entry/exit height. Levelled the van with the jockey wheel. Tow ball was sitting about an inch below the hitch. Put down the stabilisers on the van. I then hear the quadra lift compressor going look over and see the car raising and the towball going into the hitch. Crap!
Jump into the car, start it to lower the suspension, it's frozen in the raising position. I then run to the back of the van and wind the stabilisers up, then raised the jockey wheel. No damage done. Quadralift finally stops in Offroad 2 height?
I then moved the car so the towball was clear of the hitch. Lesson learnt that the quadralift has a mind of its own. I have had it do a similar thing before where it went from offroad 2 to normal height when parked and turned off.
Just thought I'd let other nomads know as some have commented that they use the quadralift to level for overnight stops.

Re: The Towing thread

Folks from the Land of Oz,

Can you get this brake controller "Down Under"?

DirecLink Brake Controller - DirecLink.com

Very easy install under the dash and the controller can be stuck on your windshield for easy removal. They use a coiled telephone cord from the main unit to the handheld, so you just unclip it and stuff it under the dash.

Have this on our Overland towing a 5500lb "caravan".....excellent system.

Thanks for that. With PayPal and FedEx etc. we can get anything. Whether it's legal is another thing but I can't see why it wouldn't be. However, I'm guessing the unit interfaces to the CAN through the elusive blue trailer plug under the dash. This could be deal breaker because for some stupid reason, export WK2's don't have this plug at least not the earlier model WK2's.

Re: The Towing thread

It actually picks up from the OBD2 port Bob. That US trailer connection is not networked.

Cheers,
Steve

Thanks Steve. That's brilliant. I wish the chip tuners would do that.

Re: The Towing thread

Some tuners do that for certain cars OBD II, I think the petrol GC can be done that way, but not the CRD yet.

I had a GDE tune on my WH Grand which was installed via the OBD port.
The advantage was that I could plug the box in and remove it at any time myself.

GDE will releasing the same type tune for the WK2 in the next couple of months. This tune will include a EGR delete.

Cheers, Craig

Hi Max,

I'm not getting the improvement I wanted from my Hayman Reese WDH installation, and found the offer above from some time back. I'm interested in your tricks!

My rig tows OK in general... no sway at high speed and quite tolerant of crosswinds... but the single axle 2.3T / 220kg van pumps the car fore and aft a bit more than I'd like on undulating surfaces. It'd be nice if the QL had variable dampening...

Anyway, I've bought a cheap HR Classic to have a play with prior to settling on a permanent set-up. My unsatisfactory installation method was as follows, and I'd like your feedback.

- levelled caravan
- measured car in Aero (QL disabled)
- matched ball height
- connected van
- restored most of lost vehicle height
- test drove in Aero
- found the trailer was steering the car on bad surfaces, general understeeer, and porpoising fore / aft still present
- tried NRH with minimal improvement
- remeasured back in Aero and found van 30mm "nose up"
- lowered ball height by 44mm (as one hole is insufficient at 22mm)
- test drive was better , but still porpoising fore and aft
- gave up with hit/miss adjustments and hit the internet

I'd like to drill the hitch shank so it inserts further... there's approximately 100mm of overhang to claw back there. Otherwise I'm running out of things to try, and the patience for stuffing about with it. I didn't really want to run a WDH, and annoyingly I'm not getting a result which makes me feel it's helping with overall stability.

Cheers,
Steve

Happy to put in my two cents worth of trial by seat of pants. My van is a JB Scorpion 19ft with tandem Ind suspension. What tyre pressures on vehicle?

Re: The Towing thread

Hi Max, thanks for stopping by 😃

I've played around with pressures in the LTs... currently have 2.8 in the front and 3.7 in the back, which is a hangover from not having the WDH installed. I appreciate that I should drop the rears a bit once weight distribution has occurred... and probably a puff more in the front.

Cheers,
Steve

Re: The Towing thread

Max I wonder if you'd experience the porpoising effect as much with a tandem???
