It’s periodically referred to as a dually truck or simply a dually. Duallies are also referred to as DRW vs. SRW. DRW was standing for twin Rear Wheels and also SRW means Single rear Wheel.

Why also have 2 pairs of rear wheels?

In a word: Traction.

Traction is the fixed a tire has actually on the road. The an ext traction friend have, the less likely is your car to shed its tight on the road and skid.

Traction is a type of friction really. So, the an ext tire surface ar coming in touch v the road, the better is your traction.

Clearly, v two rear wheels on every side, friend get dual the friction and also hence double the traction. Thus, a dually will usually get a much far better grip on the road and will be much less likely to skid.

Why usually? since traction relies on a an excellent push native both political parties – vehicle and road. V a fully loaded dually, you’ll gain much better friction due to the fact that the weight of the contents of the bed will press all 4 rear wheels into the ground. That’s a good thing. According to some drivers, as soon as the bed is empty, you shed that included traction. In fact, when you journey on gravel, girlfriend may gain too small friction through an north dually.

Another advantage of driving through a dually is that you literally have actually a spare tire going top top each back wheel. If you have a level or blow a tire, you’re much much better off – i.e. Safer – through a dually.

Is the all good? We’ll view in a minute together we look into the pros and cons of duallies.

Which pickup trucks space duallies?

Essentially, duallies are scheduled for heavy-duty trucks. These are the workhorses of the pickup world, the persons that room actually meant to be transporting bricks and also mortar and also whatnot around. With four tires instead of two, builders can haul heavier loads in the bed of your truck.

That’s why friend won’t check out a Ford F-150 dually. If you check out a dually, it’s virtually certainly one F-350, Silverado 3500HD, ram 3500 or any type of other that the herd of mammoths well-known as heavy-duty pickups.

Duallies have a slightly different trim whereby the earlier of the van has an ext “room” because that the extra set of wheels. Some human being call this a “bubble butt” due to the fact that it has tendency to do the back of the truck a little wider.

Can girlfriend convert any truck into a dually?

Hmmm… it’s not impossible to transform a smaller pickup right into a dually. In some forum discussions, people were asking about that and apparently, a great mechanic deserve to turn a solitary rear wheel truck into a dually. However, this deserve to be a facility process, together it may involve alters to the behind axle and in brand-new models, re-programming of the vehicle’s computer. So, this is the sort of “Do not shot this at home” kind of truck improvement that’s best left come the pros.

Why would someone want to do that? Well, as much as we can see, to present off. For some people, duallies room a condition symbol the sorts. The sort of world who gain an F-450 to journey their youngsters to school and also nothing an ext may also spring because that a completely unnecessary dually too.

Where deserve to you buy a dually?

You deserve to order your truck online these days and also they’ll market it to you via a regional dealership. When choosing the specs, girlfriend can also opt because that a dually. This is what that looks like in Chevy’s website as soon as you mix & match the specs of her Silverado 3500 HD:

When purchase a provided pickup, you can search many sites particularly for duallies. Just keep in mind the doing so means you’ll get far fewer results.

For example, us ran a find for lamb 3500 in CarGurus.comand it lugged up 64 listings in the area.


Ticking the “dual” crate in the rear Wheel option box reduces the results to 7.


So, end 80% of provided pickup trucks in that area are solitary rear wheel trucks and not duallies.

How much does a dually cost?

A dually is clearly more expensive 보다 a truck with only one collection of behind wheels. It’s not just the price of the two extr tires but also the specialized axle come accommodate them. The distinction in price is no too poor though. In most models, opting because that a dually will include a couple of hundreds the dollars to the invoice – commonly under a thousand.

Keep in mental that when it’s time to change the tires, you’ll need to pay for six tires rather than just four, which basically means you have slightly higher maintenance costs on a dually.

Pros and Cons the owning a dually

Before we look right into the object of towing a take trip trailer or fifth wheel through a dually, let’s quickly go end the full list of pros and also cons because that owning or control a dually. If friend have any to include – we’d love to see it in a comment.

Dually – The Pros

Higher payload capacityBetter roadway grip or traction (better stability)Improved stability (thanks come that raised traction)Improved security in case you punch a tire (you have the right to keep top top going through a level in among your rear wheels)Cool look at (according come some…)

Dually – the Cons

More expensive van (though no by a whole lot)Less selection when buying second handChanging the tires on every wheels costs an ext (150% to be exact)The truck has actually a wider “behind” which takes getting used to, especially when acquisition corners, driving in narrow lanes, or parking.

Towing a travel trailer v a dually

The additional traction that comes from two to adjust of rear wheels helps the truck carry and tow contempt heavier loads than heavy-duty trucks with a single collection of behind wheels.

So, the info we have here is native the suffer of drivers. Where it comes to testimonials from owner of duallies, there’s no question around it –

Towing with a dually pickup van offers an ext stability.

Do you require a dually van to tow a travel trailer?

Not necessarily.

After all, travel trailers are usually smaller and weigh less than fifth wheels.

You can tow a smaller trailer through an F-150 or one more half-ton truck. A 3/4 truck choose the F-250 will pull medium-sized bumper trailers there is no a problem.

When talk duallies, we’re talking around very powerful 1-ton trucks. These will probably tow just around any trailer without a problem.

Take for example one of Jayco’s largest travel trailers, the 40ft lengthy Jay Flight. As much as travel trailers go, it’s a really long and large one. Also after including the weight of hitch, complete tanks and cargo, you’re unlikely to go past 12,000 lbs. According to Ford’s manual, just about any F-350 deserve to tow 12,000 lbs and also most have the right to tow even an ext than that.

So, the bottom line is that a dually isn’t essential for towing a take trip trailer. If you’re towing a trailer that calls for a heavy-duty truck, just get the heavy-duty truck. It’ll it is in enough.

What around towing a 5th wheel?

5th wheels room a different story altogether. Because that two factors –

On average, a 5th wheel will be heavier than a travel trailer.The gooseneck hitch place a the majority of the weight straight on the truck’s bed.

For these two reasons, a dually deserve to be a great option when towing a 5th wheel.

Take this Bighorn 3160 fifth wheel, for example. At 35 ft long, this little mobile residence weighs end 15,000 lbs. Include the load of the hitch, cargo and also full tanks and we have 20,000 lbs that must be towed around.

Not just does that call for a very powerful super heavy-duty truck, this is additionally where a dually deserve to really make a difference. And owners of together rigs agree – a dually is better for towing a 5th wheel, pretty lot of any type of size. Largely because of the perfect match between a more powerful rear end and gooseneck towing.

The Bottom Line

A dually means a heavy-duty (1 ton) truck with a dual set of rear wheels.
