twin axle

[Russell E]

is this a bad choice for a motorhome? wondered if anybody knows the pros and cons of this sort of motorhome. As eventually going to live in it thinking may be more suitable for a slightly larger load, as I have old style driving licence weight not a problem. Thanks

That's why I fitted winter tyres to ours, and never suffered FWD slip again.

We are RWD with twin wheels now.

Cheers,

Jock.

Yes here always all season tyres on our vans, no major downside other that duration of the tyres although more often than not on campers the tyres expire first by years rather than miles/km wear fat or so much less of an issue.

What wobble is that then Paul? If fitted, was your air suspension faulty?

BTW, I hope you've had some joy re your heat exchanger.

Cheers,

Jock.

No jock, all the Twin wheel vans I've had had rear air. They just are not as stable as a tag (tandem).
On the hymer, can't remember about the iveco flair, the rear wheels are set much further in than the ducato Tag. The chasis is narrower,
This creates a lot more roll and wobble especially at high speeds and in winds.

With the flair, it might have been the height?

The way the arto is built, the rear wheels are set as wide as possible, this gives even better stability even in high winds..

Ours is an Iveco - If I had to judge it with hindsight and memory I would say our tag was slightly better if overtaken by an artic, or in a gusty sidewind - The Iveco does a very slight nudge, don't remember anything at all on the Tag/Tandem, but the Iveco, with standard air on the back, and VB semi on the front is very acceptable in that regard. There are other things that the Merc/tag/FWD was better at then the Iveco/twin, but overall both make a good base vehicle from my limited experience!

P.S. The Iveco might have had a wide front axle fitted, not sure - it's a long time since I read the spec sheet

Sorry chaps, but I can't agree with you re roll and wobble on the Iveco.

but the Iveco, with standard air on the back, and VB semi on the front is very acceptable in that regard.

And that's the reason why, and with 4 x new shocks, she's even better.

helps in tight places (the worst seem to be McDonald car parks).

Can't believe you wrote that. What on earth are you doing in a McDonald's car park?

Yes - Marquart shocks made a difference, as did setting the torsion bars to the weight of the van (as per the Iveco workshop manual), and setting the tyre pressures to Continentals recommended pressure rather than the van's manual, and pumping more pressure in to the VB semi as recommended by SAP near double Cartago's figure. Still not a great ride on crap surfaces though.

But the merc, whilst I think a little less susceptible to crosswinds, was very soft and liable to roll and plunge into dips etc - so I guess none are perfect, did seem a more sophisticated vehicle though.

But how much of the difference is the tag/twin for those issues, as opposed to all the other factors? So I guess if you test drive any particular van and are content or even happy it doesn't matter too much!

Adrien, I'm running at 4 x bar pressure on the rear air suspension, and 3 x bar on the front. The tyres are at 4.0 - 4.2 x bar pressure all round.
Marquart shocks weren't an option for our budget, so Monroe Van Magnums it was.

Adjusting the torsion bars is new to me.

Cheers,

Jock.
