Default What are the pros and cons of duallys?

As we contemplate buying a class B we were wondering if anyone could talk about the pros and cons of dually wheels?

The Paseo and CrossFit both have duallys and a spare wheel. Changing a single wheel is one thing but we’ve never done an inner wheel which would be just our luck to be the one that gets a flat, in the boonies. Any extra tools required?

The Paseo/CrossFit isn’t much heavier than say a Travato so apart from the high roof Transit comes with the duallys, what’s the advantage? I heard some tolls are higher because of the extra wheels.
We do like having the spare tucked underneath whereas the Travato doesn’t have one.

The aluminum wheel option makes for more access holes for the air fill valves but no extensions are included by Ford for inner. Also, no MTPS on Paseo likely due to higher weight over 10k whereas Travato has them. Yes you buy after market but ...

Dualleys get you more payload plain and simple. That's why you have them. Forget all the other reasons.

What Davydd said. Plus, the out-the-gate suspension is heavier, usually, and the handling seems more stable, particularly if you are going to tow.

Coachmen (Crossfit) is working with their supplier to provide valve extensions and should have a finalized version soon. They will be sending us a set gratis but we don't have them yet so can't tell you how well they work.

The downside is the additional cost for two more tires when you buy new and the dually means more wheelwell space is taken inside the coach - so a little less storage. It also costs about a mile per gallon.

As an aside, if you don't have the valve extensions, you can drill the inner wheel and add a second valve in a more accessible position, according to our RV tech.

I know many people do it, but I would hesitate to change a rear wheel on a converted van with the stock jack. The conversions are very heavy. On a flat surface in a safe location is one thing, by the side of the road on the berm is another. That's what roadside assistance insurance is for.

What davydd says is true IF you need the extra capacity. There are again getting to be quite a few B's that don't need the capacity of dual, so don't have them.

Similar statement would be:

If you don't require extra capacity, don't get duallies and ignore all the other reasons.

Of course this is short sighted, too, as there are other pluses and minuses to weigh against the capacity in making a dual/single wheels decision.

You will get lots of opinions, I think, but take them for what they are, opinions, and then decide for yourself.

Thanks for the input thus far.

The Paseo/CrossFit vans are heavier than say the Travato and I appreciate the ability to carry the extra load although we intend to be pretty basic and won’t be piling in loads of stuff or towing.

Whilst we prefer the Transit platform the ying to the yang of the duallys is the issue of having to replace a wheel/tire especially the rear one or the inner. Having to buy better equipment to do this and then find space to carry it seems counter productive to some extent.
It’s good to see Coachmen saying they’ll provide the extended tire inflators they seem to be more responsive than Winnebago on the face of it unless it’s just WGOs style.
Having to drill holes in wheels to get a feature isn’t confidence inspiring.

The Canadian Tribute Class B is built on Transit but doesn’t hVe duallys and has a Travato K like floor plan, much more to our liking. Their bro here even says it has TPMS. Not sure if this van will be offered in USA or meet US standards but we will keep an eye on it.

Realize roadside services can and do wheel repairs etc but if you’re off road in the boonies is that a viable option?

.

be wary of those unscrupulous upfitters...

They will sell you aluminum wheel upgrade ($$$),
but only give you the outter wheels in aluminum. The insides (out of sight) are steel. And they don't tell you that.

Big headache when you need to change a wheel,
because the steel wheel stud/nuts are different.

One more thing. Borrow a buddies dually and go for a drive in the snow or on a backroad that you would want to take your Class B. Then take a similar - single rear wheel vehicle on the same roads and see if you notice any traction differences. Try to make the best apples to apples comparison that you can when using demo vehicles. If you will never be offroad or in the snow or ice then that’s one less consideration when choosing your Class B. And yes we looked through an Okanagan B on the single rear wheel Transit chassis. Very nice layout and they did some things even better than WBO did, ie the sliding entry door layout / screen. Good luck in your search.

Did you find out why the Tribute only has single rear wheels considering its the sMe high roof Transit platform as Paseo/CrossFit? Just curious.

Sounds like you liked the Tribute but didnt buy it?

We will test drive Paseo/CrossFit...were just trying to amass info as we can so we can be more objective when we go to the RV Show in JNuary and start going to dealers.

I liked that the Tribute was on the Ford chassis with the Ecoboost, but didn’t like it was 22’ long (the tail section hangs a long way over the rear axle) and for what we do, we wanted to stick with 21’ long. Ford was also having some drive shaft issues that I have no idea how much of a problem it was or wasn’t. It had some very nice features and a similar layout to the Travato K. In BC, (and may be that way throughout Canada for all I know) Okanagan is handled by a large RV dealership/chain that we were not interested in dealing with, so we didn’t consider it seriously. That and we had already done our homework on a Travato K.

I agree that duallys are for higher payloads. Having said that, I would not buy a Class B (or even a pickup for that matter) that was so heavy that it required dual rear wheels. I don't need the downsides of duallys including buying extra tires, changing inside flats, getting rocks stuck between the two tires on backroads, etc..

It really isn't that hard to design a Class B that is below the payload limits of vans with single tires. That is even the main draw of a Class B - smaller, lighter and more mobile than Class C's, Class A's, etc.. Then I would spend the extra money on suspension upgrades which can offset any ride qualities of duallys.
