Types of 5th Wheel Hitches

A 5th wheel hitch is a generalized term for a wide range of hinges mounted on the back of a car and used to pull a fifth wheel. The difference in the categories of a fifth wheel hinge depends upon the mechanism it uses to pull a load or the type of connection it establishes with the pack.

How Do I Choose a Fifth Wheel Hitch?

Most of the tow trucks or semi-trucks already come with a hitching system attached to them. You can also get a 5th Wheel Hitch attached to your tow truck in case it already doesn’t have a Hitch attached to it.

Determine the type of Hitch

Two trucks or semi-trucks usually come in standard two-bed length, namely an eight feet bed or a 5.5 feet bed width. With the shorter vehicles, you need a Hitch with a longer rope or a sliding fifth wheel hitch that can give you enough space on turning. 

With a longer truck bed, you can attach a fixed fifth wheel hitch without any worries, as it will provide you with sufficient space to make a turn with a load connected behind.

How Big a 5th Wheel Can I Pull?

The size of the 5th wheel that you can pull directly depends upon the gross weight of your vehicle. The Gross weight is the total of the car’s total weight plus the total weight that payload weight that it can carry. 

You can find the total weight or the gross weight in the detail section of your vehicle. The gross weight varies from vehicle to vehicle depending on their model and the installed parts.

In general, it is safe to tow lower than 1800 lbs of weight, but in some towing trucks, you can go beyond that limit and tow weight up to the weight of 30,000 lbs. You can check the maximum weight that your vehicle can pull by subtracting the weight of the empty vehicle from its total gross weight. 

The remaining weight that you get will also include the load of the material inside the fifth wheel. So, you also need to put the weight on the material and person the 5th wheel will be carrying. Towing a fifth wheel beyond the safe limit can cause fatal accidents, so it is better to keep the weight of the fifth wheel as low as possible. 

Do I Need a Slider Hitch for a 6–9 Bed?

Having a slider hitch gives you more flexibility when taking turns. In the case of a shorter bed, if you have a fixed hinge, then there is a high chance that you may not get enough torque while taking a turn, or your fifth wheel may even hit your vehicle. 

A sliding hinge becomes a necessity in the case of beds of miniature size like 5 feet, but it won’t be as necessary in the case of a 6-9 feet bed.

A sliding 5th wheel hitch on a 6-9 feet bed will surely give you an advantage over a fixed hinge system. You can get easier turns and smoother towing with a sliding hinge. Purchasing either of them depends upon the availability and your budget. 

The sliding hinge can be a little costlier than the fixed hinge due to the additional parts like a sliding platform or rail and additional installation charges.
