What is a dually truck?

A duel rear wheel truck (DRW) is used for very heavy-duty purposes like heavy pickup with two rear (back tires) wheels on both side. These four rear wheels provide more road contact and width for greater stability, more balance, and more traction. If you get a chance you have been behind one of this kind of truck you definitely notices large and muscular fenders with big four back wheels instead of two wheels. 

 
Also you need to change rear axle as well for install these four strong wheel. These axel handle big playout weight and defiantly gives you more towing capacity as compare to any normal truck with two rear wheels (SRW). Most dually truck also equipped with bigger brakes for extra stopping power and you definitely need to change shocks and springs for haul more load. 

 
Mostly people use dually truck (DRW) for connect gooseneck hitch for haul more weight. If you have SRW and truck haul heavy load and the weight shift towards the rear vehicle it may cause instability and loss the control. A DRW have two additional back wheels provide more stability and can handle heavy load with less risk. The one of the main think is this conversion SRW to DRW is very costly. 
 

 
Why is it called dually? 

Dually truck can carry more weight then normal truck the reason behind this is they have four rear wheels instead to two. This dual wheel provide several advantages like increase weight capacity, better stability, Braking and your truck looks aggressive and bigger.   

 
Increase weight distribution with two sets of rear wheel it means weight you haul is distribute equally over all surface area and also reduce the weight on each tires. This allows dually truck carry large weight as compare to normal truck without putting too much stress on every tire. The two extra wheels also provide more tire to road contact it means increase traction of the truck. It is very important for those vehicle who carries heavy load this thing also help to prevent the wheel from slipping from the road. 
 

Dully truck is more stable as compare to normal truck when they carry heavy weight because the two extra wheel provides wider base and lower center of gravity it the main cause of grip on read while driving. In DRW also provide better breaking system then normal truck because it carry heavy load then normal truck breaking power helping truck to stop quickly and safely during driving. 

Dually vs single rear wheel 

As I already explained previously dually truck has two pairs rear tires instead of single set of rear tire. Dually truck is mostly used for pickup heavy load because of it’s four back wheels. These wheel provides it more power and traction on road. This dual rear wheel (DRW) provides greater stability which makes perfect for hauling and towing heavy load. This truck mostly used in industries and for commercial use because dual truck’s axel also upgrade like tires for hauling heavy loads. Dual truck also provide high load capacity and improve weight distribution weight and it also enhances control. This thing make dually truck ideal for industries and also for commercial use link in deliveries, construction, agriculture and logistics. 
 
The bad thing of dually truck is this truck is not fuel efficient as compare to single rear wheel (SRW). Single rear wheel truck is cheap per mile compare to dually truck but SRW is not stable and it also less proves traction on the road. Single rear wheel truck is powerful but not as DRW this only this Dually truck is more beneficial for industries use. Most of the business in USA that demands only dually truck  because of his durability, performance and stability also provide more traction on road. 

 
 
Pros of dually trucks 

 
 
As I mention early dually truck is a normal truck with four rear wheels. SRW is chosen by those people who didn’t have any concern with large storage capacity, style more traction in simple word those people doesn’t like dually truck who do need any extra prover for delivery, more weight hauled capacity, those who do not like bulk body. Dually truck have more weight hauling capacity then single rear wheel, Defiantly DRW has more stable then SRW specially in stroms and windy situation. It is perfect for towing trailer like goose neck trailer. 
 
Dually truck are knowing for their power, torque which make this truck more useful. Mostly dually truck have diesel engines and diesel engines already famous for the power and roar. Dual truck have more durable and longevity then SRW. This thing make it more suited and heavy duty applicable. Most dually truck has diesel engines that’s why these engines hold their good value batter then gasoline engines. I think this is pretty much to introduce dually truck and their towing capacity which them desirable to buyers who looking for reliable and capable truck. Dually truck have more payload capacity. Payload capacity is maximum weight a truck can safely carry 

 
 
Cons of dually trucks   

Dually trucks also have some cons as well like decreased fuel economy, it is also difficult to park and drive in rush and in city traffic because of his wide and heavier body. It is more expansive and also difficult it’s maintains. it is less comfortable ride as compare with SRW. It burn more fuel as per mile. 
Dually truck also need some extra maintenance because there are two more tires to maintain and replace that means you’ll pay more money for tires and breaks as well. 

 
 
Best uses (towing, hauling) 

 
As you know a dually truck is a pickup truck with four rear wheels. Dually truck is an ideal for towing trailer. Normally dually truck are designed to handle higher weight loads and provide more stability, traction when towing heavy trailer which can make them perfect choise for towing large fifty-wheel trailer. 
 
Every vehicle has a specific towing capacity which is maximum amount of weight it can safely tow. You’ll need to know this number for your vehicle. Dually truck generally provide more stability when towing especially in windy situation or when semi truck pass by it because the two rear extra truck help to distribute the load and provide perfect stability and traction. 
 
Butt you defiantly need about your truck payload capacity. Payload capacity is maximum weight a truck can safely carry. Dually truck have higher payload capacity the single rear wheel trucks. In simple word if you are towing large and heavy weight like fifty wheels trailer a dually truck it is ideal for this. 

 
Fuel economy 

Fuel economy details the number of miles your vehicle can drive per gallon of fuel. You can measure diesel truck miles per gallon y dividing number of miles you can drive until your tank is empty by the capacity of tank. According to Jay Lavender (Quora User) the average mpg on the trucks is 7 mpg. You might get better fuel milage or worse 

Fuel economy also depend on weight you can haul. Diesel truck cover long distance and heavy loads that why it is more efficient fuel intake means spending less time and money at the gas station it is also fewer negative effects on environment.
