Although few people think of them in this manner, the trailer is among the oldest forms of wheeled transportation. Civilizations as far back as ancient Egypt had already come up with the idea of the chariot, and the idea of a towed payload has persisted throughout history.
Naturally, the development of heavier vehicles has caused trailers to change as well, and these days it is possible to see small cars towing things far bigger than themselves. The tractor-trailer truck, known in many locales as a ‘big rig’, has become the economic lifeblood of whole countries.
With trailers as big and complex as the cars that are pulling them, it should come as no surprise that trailers have their own considerable world of accessories. Some, such as lights or tires, are shared with other things on the road; others, such as the trailer jack, are used exclusively for towed vehicles.
Unlike an ordinary car jack, which tends to be used in repair work, a trailer jack can be used even when the trailer is in good working order. Large trailers especially will use the jack not only to attach and remove a trailer from the hitch but also serve as makeshift supports under trailers that would otherwise be unevenly balanced and dangerously unstable.
With such an important role for anyone dealing with trailers, it should be clear to all why you need the best ones. Here are five of the best models to use with your trailer.

Hauling large campers or shipping containers means a serious health and safety risk, both to yourself and to others around you. A proper trailer jack can seriously mitigate the risks, preventing tipping accidents and sparing serious damage to the trailer and its surroundings.
For many, having a good jack will be necessary just to get on the road. Without a jack, attaching a large freight trailer to a rig can be all but impossible.
When buying your jack, take into account both the shape of the trailer and where it is likely to be parked. Try to pick a trailer jack and hitch that will keep your vehicle streamlined and within a designated parking spot – protruding attachments can be almost as damaging to other cars as actual unsafe driving, and are far more liable to be clipped off by accidents.
It is worth mentioning that while all of these jacks should be more than capable of raising or lowering your trailer safely, they are still supporting and moving what is effectively another car. Make sure you and others keep a safe distance before activating your trailer jack.
