What is a tow vehicle?
A tow vehicle is a vehicle that can tow a trailer, fifth wheel, or any other vehicle behind it. Examples of tow vehicles are:
- SUV or sport utility vehicle
- CUV or crossover utility vehicle
It is worth knowing that all tow vehicles cannot tow everything behind them because of their towing capacity.
Let’s look at the towing capacity of different towing vehicles:
- A full-size car can tow up to 3.5k lbs.
- A crossover can tow up to 3.5k to 12k lbs.
- Minivans can tow up to 3.5k to 12k lbs.
- ¼ ton truck/SUV can tow up to 3.5k to 12k lbs.
- ½ ton truck/SUV can tow up to 16k to 20k lbs.
- A ¾ ton truck can tow up to 16k to 20k lbs.
- A 1-ton truck can tow up to 16k to 20k lbs.
The stronger the towing vehicle the larger weight it can tow behind itself. That’s why you should know the towing capacity of your vehicle before you tow something behind it. Towing beyond the capacity can blow off the engine or damage it in the long run.

What is a trailer?

- Pop-up campers
- Car haulers
All these trailers have different GTW (gross trailer weight) and TW (tongue weight) that you will find later in this article.
A trailer hitch is that keeps the trailer and the tow vehicle together with other components. It can be welded or bolted onto the vehicle. There are many types of trailer hitches in use.

3. 5th Wheel Hitch
It is mounted into the bed of the truck over the rear axle. You can haul a travel trailer on it. Here the coupling is a part of the hitch. the kingpin of the trailer is received on the hitch and the hitch safely holds it with its jaw mechanism.

6. Bumper Hitch
It is attached directly to the bumper of the vehicle. It is used for towing a lightweight trailer.
7. Weight Distribution Hitch
The weight distribution hitch distributes the weight all across the tow vehicle and the trailer like this one.
8. Sway Control Hitch
A sway control hitch uses a variety of components and techniques to make sure that the trailer does not sway while it’s moving. These are the most expensive hitches out in the market. They use chains, pulleys, and hydraulic pistons to safely pull the trailer.
A few good sway control hitches in the market are Blue Ox Sway Pro, ProPride Hitch, and Hensley Hitch.
Trailer Hitch Parts
There are different parts and component which makes a trailer hitch. let us look at them one by one.
1. Ball Mount
A ball mount is comprised of a shank and trailer ball platform. The shank is inserted into the hitch receiver tube, and the platform provides a solid base for the trailer ball.
It comes in many varieties where some are fixed means they are made up of one piece and others are adjustable according to the need. Generally, there is a hole in the shank for the hitch pin or hitch lock.
2. Trailer Ball
It is a connection point between the trailer and the vehicle. It is comprised of a metal ball and a threaded shank. A trailer ball is needed as when connected to the trailer coupler the trailer ball allows you to turn around corners easily.
They come in different standard sizes.
3. Hitch Pin
It is a metal rod that keeps the ball mount shank from sliding out of a hitch receiver tube. Generally, hitch pins come in an “L” shape.
4. Trailer Coupler
A trailer coupler with the help of a trailer ball connects the trailer to the vehicle. They come in standard sizes and you can adjust most of them. The size of the trailer coupler must match the size of the trailer ball for maximum safety.
5. Safety Chain
A safety chain is a metal chain that is strong enough to keep the trailer from complete separation if the hitch fails. For better safety use two safety chains.
6. Trailer Wiring Harness
A trailer wiring harness is a wire which allows the vehicle’s electrical system to connect to the trailer. It supplies power to the trailer taillights as by law it is mandatory to have tail and brake light in the trailer.
