I purchased my new motorhome and travelled nearly 18,000km on tar roads and freeways, complaining about the hard "truck like" ride on the road. Then purely by coincidence a very observent Iveco area service supervisor pointed out that the gap between the top of the front tyre and the wheel arch trim above was excessive. Closer inspection revealed the real problem - the front suspension torsion bar had been wound up to maximum, causing the control arms to sit hard against the bottom bump rubber. In effect, I had no verticle movement in the front suspension which explained the rough ride. With the torsion bar now set correctly, it now rides more like a car on the road.
The distance from the centre of the front wheel to the mudgaurd trim above was 535mm which indicated the fault which is now 475mm after correcting the fault. It concerns me, that there are a number of motorhomes with this potentially dangerous condition on the road, evidenced by the excessive gap above the front wheel. If your Iveco based motorhome is rough riding on the road, then it may pay to have the suspension checked to see if the control arms are sitting on the bottom bump rubber.
Had the same problem on my Iveco , they must be imported that way.

Hi Goldcoaster, not sure who is to blame but my Iveco was built in Spain and the manufacturers paint seal on the torsion bar adjusting nut was broken, indicating that settings were changed after leaving the factory. Also not sure why it was done, possibly to bandaid non-compliance with Australian Design Rules. Fair Trading have been notified as it appears that motorhomes are still being sold with the potentially dangerous condition.

Could be to stop them bouncing about during shipping. If they had them chained down close together and the suspension was set normally, they may bump heads with each other.

Yes I did consider that but Iveco assures me that it is not the case and I must admit that it would not be practical to do so.
