What Size Jack Do I Need For My RV?

There are a few things you’ll need to consider when purchasing a jack for your RV. The most important factor is the weight capacity of the jack, which is determined by the size and construction of the jack. You’ll also want to consider the height capacity, as some jacks are not tall enough to reach the ground on certain RVs. Finally, think about any special features that might be useful, such as a built-in level or quick release mechanism.

When it comes to weight capacity, most jacks can support between 3,000 and 5,000 pounds. If you have a particularly large or heavy RV, you may need a jack with a higher weight capacity. For example, if your RV weighs more than 7,500 pounds, you’ll need a jack that can support at least 6,000 pounds.

When it comes to height capacity, most jacks can reach between 18 and 24 inches. However, some jacks have a maximum height of just 15 or 16 inches. If your RV is particularly tall, you may need a jack with a higher height capacity. For example, if your RV is more than 30 feet long, you’ll need a jack that can reach at least 27 inches.

Finally, think about any special features that might be useful. A built-in level can help ensure that your RV is level when parked. A quick release mechanism can make it easier to remove the jack from the RV when you’re ready to hit the road.

When it comes to choosing a jack for your RV, weight capacity and height capacity are the most important factors to consider. Be sure to choose a jack that can support the weight of your RV and is tall enough to reach the ground. You may also want to look for a jack with special features like a built-in level or quick-release mechanism.


One way to test your RV jack is to place a level on top of it. If the jack is level, then it's working properly. Another way to test your jack is to try raising and lowering it a few times. If the jack doesn't move smoothly or feels like it's getting stuck, then it may need to be replaced.

A few signs that your RV jack may be going bad include difficulty in raising or lowering the jack, a binding feeling when trying to operate the jack, and leaks from the hydraulic fluid reservoir. If you notice any of these symptoms, take your RV to a service center for further inspection.

Most RV jacks can last for many years with proper care and maintenance. However, if you use your jack frequently or if it's exposed to harsh weather conditions, you may need to replace it more often. It's a good idea to inspect your jack regularly for signs of wear and tear, and to have it serviced by a professional if necessary.
