What I would like to know is what do WDH's actually do & are they required on all vehicles for large caravans?
We had a Jayco Swan a few years back that we bought second hand. It came with a WDH. The previous owner had a commodore
sedan & always used the hitch.
We used it once & never again. We found it wasn't worth the effort of putting it on. We towed it with a Patrol Wagon with heavy duty
suspension & the Swan was only a lightweight van.
We also used the Patrol to tow (at separate times) a 2.2 tonne boat & a 1.5 tonne single axle trailer carrying quads without a WDH & they both towed fine.
At the moment we have a Hilux 2 door ute, which is a much lighter vehicle & are thinking of buying a van up around the 2 tonne mark.
The tow ball weight on the towbar of the Hilux is a max of 225kg.
Will a WDH be required or can I change the
suspension on the car to compensate for the extra load?
Your thoughts please

Hi Fatso,
I have a 2000 Prado with heavy duty springs all round, and up until recently had a Eagle outback camper. I didn't use a WDH with the Eagle, it caused the back of the car to sag about 10 - 15 mm, front end didn't lift at all, and I think the ball weight was around 110 kg. I did feel at times that the front end felt a little light and vauge.
We have just picked up an Expanda poptop, with an empty ball weight of 150 kg (factory weighed). I did buy a WDH for it. (EAZ Lift 600 lb). We towed it
home with out the WDH, and it towed OK, but again had that feeling of the front of the car being light.
I spent some time the other day setting up the WDH, taking measurements as I did it.
When I hooked up the van (fully loaded), the height of the towball dropped 40 mm, the rear
suspension dropped 20 mm and the front
suspension lifted 15 - 20 mm.
After connecting and adjusting the WDH, the rear
suspension was now 5-10 mm sag, and the front
suspension sag was back to 0 mm sag.
Driving felt alot better, none of the vaugeness or lightness felt in the front end, and very little of the "see-saw" from the back when going over bumps etc.
So in my opinion, I think the WDH has been worth it, I feel much safer driving when towing, and for $550, probably compares in price to the cost of changing the car
suspension.
