Hi, looking @ a WHD or a Stabilizer for our 2006 Jayco Destiny Poptop. Is it worth having either on a van of our size. It sites pretty level on the Dmax (as per pic) and seems to travel well. Only problem is it seems to wallow on undulating roads. Maybe shocks on the ute might fix this.
Gday Dave
Re = the wallow - have you checked your tow ball down weight of the van or is the van packed with too much weight in the rear? These are 2 things I would check. As you say the van looks pretty straight in the pic.

From the picture it looks to me like the bum us down on the ute - maybe 40mm or so which indicates to me that the rear springs are carrying too much weight either via towball down weight or whatever you are carrying in the back of the ute like batteries or a generator. This will cause wallow which is dangerous to say the least. The fix for that is a WDH and/or airbags for the rear which will help balance the unit..
Last night we were linemarking on the Warrego Hwy east of Chinchilla and the road there is notorious for either snapping caravan drawbars and/or causing the van to lose control due to the wavy road. (Trying to apply a straight line on that type of road is very difficult BTW.)
Good Luck.
Hi Dave. We had the same problem with our DMax SX. We deliberately bought the SX model as the rear springs are stronger and stiffer than the other models.
But we had to play around quite a bit to stop a little bit of sideways sway on some roads - often increasing speed on a downhill corner. BTW we have ESC fitted to our 'van.
The trick was to take some of th tow ball weight off - in our case we but some weight in the rear of the van and made sure our van water tanks are always full - no more sway.
I asked a Isuzu dealer and they said not to put air bags on leaf springs as you will stress and may be snap them = better it add a kit set extra spring - advertised online and according to their adverts, easy to it lol
Meanwhile, if you do get sway, don't brake !!!! Increase you speed and the sway will stop within a second or so and then you can ease back on your speed

Our experience is totally the opposite. We had problems with our van swaying and the faster we went the worse it got - the solution was moving the wheels back and re-aligning the springs. Get expert advice rather that anecdotal opinion so prevalent on many forums.
In my experience, wallow (as opposed to sway) will always occur to a certain extent on undulating roads. A WDH will assist in minimising this to a certain extent, however I suggest that you consider upgrading the rear suspension on your ute. I have the same problem occasionally with my D40/Jayco Sterling combination and intend to do just that (btw I use a wdh despite the fact that my van travels well without it and does not sway at any time, even at 100+). In the interim I suggest reducing speed a bit on the worst bits of road will help.
If the van sways at all you have a problem with weight distribution
