What Size Truck Do You Need To Pull A Fifth Wheel | All Your Questions Answered

Are you planning to pull a fifth wheel and wondering what size truck do you need? Get all the answers plus tips on selecting the right truck for your needs.

When buying your first fifth wheel, it’s essential to make sure that your truck has enough power to tow the combined weight of your trailer and cargo safely.

However, every truck buyer can agree that it can be tricky to know exactly what size truck you need to pull a fifth wheel.

The size of the truck you need to pull a fifth-wheel trailer depends on the weight of the trailer itself. Fifth-wheel trailers are generally larger and heavier than conventional travel trailers, and they require a truck with sufficient towing capacity to handle the load safely and effectively.

Let us explain to you the different factors that determine the size of the truck you need to pull a fifth wheel so that you can make an informed decision when purchasing your truck.

Choosing The Make And Model Of Your Truck

The type of truck you choose can also affect the performance and safety of towing your fifth-wheel trailer.

A lighter, more efficient truck may not provide as much power as a larger truck, making it more difficult and dangerous to tow.

On the other hand, a larger truck may provide more power than you actually need, resulting in greater expenses and decreased fuel efficiency.

Make sure to choose the right truck that can provide the right power and stability for your fifth wheel.

Gross Combined Weight Rating

The first thing you need to determine when considering what size of the truck you need to pull a fifth wheel is the gross combined weight rating (GCWR) of your truck.

The GCWR is the maximum allowable weight of your truck, including passengers, cargo, and trailer.

Your truck’s GCWR must be more substantial than the total weight of your fifth wheel and everything you plan to bring along with you.

Truck Engine Size

The second factor to consider when choosing the right size truck to pull a fifth wheel is the engine size.

The engine power determines the power that the truck generates to pull the fifth wheel.

Generally, a bigger engine size will be more powerful, and therefore, can pull a larger fifth wheel with ease.

It’s best to choose a truck with a minimum V6 engine that can produce enough power to pull your fifth wheel.

However, a V8 gas engine or a diesel engine will have even more power for towing heavier loads, maybe think about the hill climbs you will be doing as well.

Payload Capacity Of Your Truck

Next, you need to consider the payload capacity of the truck.

This refers to the amount of weight that your truck can safely carry in the bed.

This weight includes the weight of all of your cargo, passengers, and the hitch.

Make sure that the payload capacity of your truck is enough to handle the weight of your fifth wheel and all of your gear as remember the fifth wheel will be sitting in the bed of your truck.

Length Of Your 5th Wheel

Aside from the weight of your trailer, the length and height of your fifth wheel are also important factors to consider when choosing the right size truck.

The length of your fifth wheel will determine the turning radius needed for maneuvering your trailer.

The height of the fifth-wheel trailer, on the other hand, will determine how high your truck bed needs to be to keep the trailer level.

Ensure that the truck you choose has the appropriate bed height and turning radius to comfortably tow your fifth-wheel trailer.

Truck Axles

The next factor to keep in mind is the truck axles.

Manufacturers build trucks with different axle ratios to cater to various jobs.

An axle ratio depicts how many times the truck’s driveshaft rotates for each revolution of the wheel.

A lower axle ratio means the engine will rotate fewer times to achieve the truck’s desired speed, which translates to more fuel efficiency.

Nevertheless, a higher axle ratio means that the truck will have more power and torque to tow a heavier load.

Breaking System

The braking system is a vital factor when you are considering the size of the truck you need to pull a fifth wheel.

The truck must have a good braking system to help control and stop the trailer.

A fifth-wheel trailer has a lot of momentum, which means that a poor braking system can be a recipe for disaster.

It’s also essential to bear in mind that most states require a braking system for any trailer weighing over 3,000 pounds.

Suspension System

Lastly, your truck’s suspension system also determines the size of the truck you need to pull a fifth wheel.

A fifth-wheel connection places a considerable amount of weight on the back of the truck.

Therefore, a proper suspension system will help give the truck a better ride while still maintaining stability when towing heavier loads.


When purchasing your truck, make sure you have done your research on the factors mentioned above.

Keep in mind that each truck manufacturer produces their trucks with varying specifications, so knowing your towing needs can help you choose the right size of the truck to suit your needs.

A powerful engine and a good breaking system are crucial elements to a successful towing experience.

So, take the time to assess your towing needs, consider all the factors, and make an informed decision to ensure the safe and smooth towing of your fifth wheel.
