Which RV Leveling Jack Is Best For My Trailer

Which RV Leveling Jack Is Best For My Trailer

Having adequate jacking systems is a critical part of RV functionality and enjoyment. As any seasoned RVer knows, recreational vehicles can easily become sloped or unstable when parked at campsites and overnight locations that lack perfectly flat, level ground. This tilting and shifting can make moving around inside uncomfortable, cause appliances to malfunction, and disturb sleep. That's where jacks become vital - they actively lift and support the camper to counteract the natural unevenness of most parking sites. Jacks provide a solid, stable base that RVers can depend on when settling in for the night. They serve as the foundation for pleasant camping and peaceful rest.

There are two main jacking systems that RVers rely on: stabilizing jacks that support slide-out rooms, and more robust leveling jacks that re-orient and lift the entire RV body. Understanding the difference between these two types ensures you choose the right jacking capabilities for your camper and travel style. Properly outfitted, jacks make leveling and stabilizing a breeze so you can relax and enjoy your site.

Why You Need to Level an RV?

Having your RV parked on a completely level plane is extremely important for several reasons. RVs parked on even a slight incline can cause major headaches and problems over time. The first main issue is comfort, trying to sleep in a tilted bed or relax on uneven furniture is uncomfortable. Spilled drinks and sliding cabinets make simple tasks frustrating. Appliances like refrigerators also require being level to operate efficiently, as do slide-out mechanisms.

But even more concerning is the strain that being parked at an angle puts on various RV components. The suspension and frame bear extra asymmetric loads that lead to premature wear. Seals and connections in the plumbing system are prone to developing leaks under the added stress. Doors and cabinets may fail to align properly. There is also the risk of appliances like fridges and furnaces malfunctioning if their level orientation is off. Even the tires undergo extra duress from an imbalanced weight distribution.

An un-leveled camper experiences forces and loads it was not designed for. This compounds over time resulting in expensive repairs and compromised performance. Having your RV precisely level when stationary eliminates these issues. So being level is about far more than just comfort, it preserves the structural integrity and function of your entire trailer for the long run.

What Is the Difference Between Stabilizing Jacks and Leveling Jacks?

RVs can easily become sloped or unsettled when parked on the naturally uneven ground of campsites. RVs are equipped with specialized jacks to counteract these concerns.

There are two main types of jacks that serve distinct purposes - stabilizing jacks to support, and more heavy-duty leveling jacks that re-orient the entire RV. Understanding the key differences between these two jack types will ensure you have the proper jacking capabilities for smooth travels.

Now let's explore exactly how stabilizing jacks and leveling jacks differ. We distinguish them on five points of difference.

  • Different Purposes:

    What is Stabilizing Jack?

    Stabilizing jacks are essential components of an RV's leveling and support system. Unlike leveling jacks that are primarily used to adjust the RV's height to create a level surface, stabilizing jacks are designed to minimize movement and swaying within the camper once it's parked and leveled. Stabilizing jacks are strategically placed at various points around the RV, typically near the corners, to distribute the weight evenly and counteract any potential rocking or swaying. They can be manually adjusted to apply pressure against the ground, effectively minimizing the trailer's movement.

    The primary purpose of stabilizing jacks is to enhance the overall comfort and safety of the RV occupants while stationary. When an camper is parked, even a slight movement inside can feel magnified due to the confined space. Stabilizing jacks counteract this motion by providing additional support and reducing the effects of vibrations caused by people walking around, appliances running, or external forces like wind gusts.

    What is Leveling Jack?

    Leveling jacks serve a different purpose, getting the entire RV chassis level when parked on an uneven surface. Leveling jacks must have high weight capacities to safely support thousands of pounds. They are mounted to the RV frame with reinforced welds.
    Leveling jacks lift the frame to counteract the slope of the site. The goal is to get all tires resting evenly on a flat plane to stabilize the trailer and keep the interior living space oriented horizontally. Level jacks must bear the entire loaded weight of the RV.
    Precisely leveling an RV with jacks allows refrigerators, slide-outs, and other appliances to function properly. It also prevents damage from frame stress and uneven wear. Leveling your trailer brings comfort when moving inside and ensures everything operates correctly.

  • Different Structures:

    Stabilizing Jacks typically have a scissor or X-shaped structure to increase height and support. The arms retract and fold together when being stowed for travel.
    Act to stabilize by simply extending straight down and applying pressure, not lifting the RV. Usually manually operated by a hand crank or chuck key to open and close the scissor arms.

    Leveling Jacks most often have a cylindrical screw or telescoping post design to provide maximum lifting force. The round vertical shape allows them to screw in and out of sleeves or tubes, raising and lowering the RV frame. Electric drive motors rotate the screw to lift each corner separately to attain level. Can adjust height more dynamically thanks to rotary rather than just up/down motion.

  • Different Weight Capacities:

    Stabilization jacks are designed and rated to only support the weight of the confined space, not the entire RV. It is still a few hundred pounds at most. However, the entire camper weigh nowhere near thousands of pounds. Therefore, the stability jack only needs to be of sufficient capacity to securely hold the confined space without lifting or orienting the RV itself. Their sole purpose is to minimize slip-out motion.

    Leveling jacks must be extremely robust to lift the entire loaded trailer weight, which can easily surpass several tons for large travel trailers or 5th wheels. All that vehicle weight presses down on the jacks as they lift and orient the frame. To reliably handle these heavy loads without buckling, leveling jacks are constructed from high-strength steel and have heavily reinforced mounting plates. The materials and structure must be over-engineered with an ample safety factor to prevent failures under thousands of pounds of force.

  • Different Operation:

    Stabilizing jacks are operated by simply rotating the hand crank to lower them vertically down until they firmly engage the ground, supporting that confined space.
    To level the RV, leveling jacks must be raised and lowered in a synchronized sequence to individually lift each low corner until all tires are on the same flat plane. This is a more complex lifting and stabilizing procedure.

  • Different Prices:

    Manual stabilizing jacks are relatively inexpensive auxiliary RV components. Slide-out rooms already require large motors and gears for extension, so simple stabilizers suffice.

    Leveling systems range from budget manual screw jacks to deluxe automatic computer-controlled systems costing thousands. Electric motors and automation increase costs over basic manual cranks.

Can I Level My RV With Use Stabilizer Jack?

Stabilizer jacks are not a substitute for proper RV leveling jacks. Mistakenly attempting to lift or level the entire camper chassis with stabilizers can lead to catastrophic failures. Stabilizer jacks lack of the structure, capacity, placement, and range of motion required to safely orient the vehicle’s weight.

Purpose-built leveling jacks have the muscle to lift thousands of pounds and adjust each corner’s height as needed to attain a level attitude. Operating stabilizers outside their intended use jeopardizes equipment, home structure, and personal safety. Take the time to install suitable leveling jacks that actively lift and distribute the RV’s weight. With an appropriate leveling system in place, stabilizer jacks can then provide their intended slide support function.

Types of RV Stabilizer Jacks & Leveling Jack

We'll shine a spotlight on some of the most common types of these essential tools, offering insights into their functionalities and advantages. Whether you're a seasoned RVer or new to the adventure, delving into these select stabilizer and leveling jacks will equip you with the knowledge needed to elevate your camping escapades to new heights of convenience and enjoyment.

Stabilizer Jacks

  • Scissor jacks

    Scissor jacks are a popular style of jack utilized for stabilizing. Their scissor-like arm structure that opens and closes to adjust the jack's height. A manual scissor jack uses a hand crank or detached chuck key to rotate a screw mechanism that pushes the arms apart, extending them vertically down to the ground. Weight on top presses it firmly into place. Reversing the crank lowers the jack by allowing the arms to fold back together. They can expand high enough to effectively stabilize the room when deployed. Weight ratings typically max out around 5,000 pounds. Scissor jacks deliver an ideal balance of strength, stability, ease of operation, and it is a popular choice among RV owners. However, while this type of jacks is sturdy, they aren’t designed to stabilize rather than lift the trailer.

  • Drop-Down Jacks

    Drop-down jacks are a type of mechanical support device used for stabilizing trailers and RVs. These jacks are designed to be adjustable, providing versatility in lifting and supporting loads of varying heights. They are typically operated using a crank mechanism or an electric motor. The crank mechanism allows users to manually raise or lower the drop leg to the desired position. Some modern drop-down jacks feature motorized operation, enabling users to adjust the height with the push of a button, which is particularly convenient for heavy loads. However, we need to make sure to avoid overloading jacks.

Leveling Jack

  • Manual Leveling Jacks

    Manual leveling jacks utilize a hand crank to turn a screw mechanism that raises and lowers each jack, providing a simple and practical leveling solution. However, the weight capacity of a single manual jack is limited, so a system of multiple jacks working in unison is needed to safely lift and stabilize the RV. Operation requires carefully adjusting each jack progressively to attain a level condition. With proper setup and use, they are easier to maintain and can bring savings to RVers on maintenance costs.

  • Electric Leveling Jacks

    Electric leveling jacks utilize 12-volt DC electric motors and gears rather than manual cranks to raise and lower each jack. This allows RVers to level the trailer chassis simply by pushing buttons on a wired remote or wireless control panel. Electric jacks make the leveling process far simpler, faster, and less physically demanding compared to manual jacking. While more expensive than manual jacks, power jacks greatly enhance ease of use and convenience. Their electric operation and automated features are perfect for today's large RVs.

  • Hydraulic Leveling Jacks

    Hydraulic leveling jacks utilize hydraulic fluid pressure to raise and lower jacks, allowing precise control. Hydraulic jacks have a higher weight capacity compared to manual or electric jacks, making them ideal for large, heavy RVs. They provide reliable leveling on all terrains for extra-large camper that electric jacks cannot safely handle.

How to Choose the Best Leveling Jack for Your RV

RV’s Specifications, Consider the Leveling System, Evaluate the Installation Process, Check the Warranty & Customer Support, Price.

  • Weight of RV: Leveling jacks come with weight ratings, so make sure to choose one that can handle the fully loaded weight of our camper. Go with a high weight capacity to give yourself a buffer.
  • Decide on electric vs manual operation: Electric leveling jacks require less physical effort but need a power source. Manual crank jacks don't rely on electricity but do require more manual labor
  • Look at lift height and stroke length: The lift height is how high the jack can raise your RV. The stroke length is how far the foot pad moves up and down. Make sure both meet your needs.
  • Make sure the jacks are designed to fit your camper properly. Look at where they need to mount on the frame.
  • Factor in ease of use features like auto-leveling, one-touch operation, and remote controls.

Why Put Blocks Under The Jack?

  • Placing blocks strategically underneath stabilizing jacks and leveling jacks when parking your RV can provide a number of worthwhile benefits.

  • Jack blocks protect the ground surface at the campsite or parking location from damage. Jacks that screw or dig directly into dirt or grass can leave ugly marks or holes, as well as tear up the area. Elevating them with blocks prevents this type of site disruption.

  • Blocks also give the jacks a much broader and stable base to operate on. Soft soils can allow jacks to shift and sink into the ground, causing the RV to rock unsteadily. Getting them situated on a solid block provides a reinforced foundation to keep jacks and the trailer from moving around.

  • In some cases, blocks can help compensate for minor ground unevenness by evening out the surface height under each jack. This aids in attaining a level RV orientation. Blocks also provide a bit of extra jack height if needed to lift the camper chassis higher. The less the jack is extended, the less it will flex and wobble.

  • Setting jacks on blocks gets them up out of any mud, sand, or debris on the site. This keeps the stabilizing and leveling mechanisms cleaner for smoother operation and extends equipment life. Ground debris can quickly wear down jacks.

  • Jack blocks dampen noise and vibration that result from jacks vibrating against the bare ground. Blocks provide acoustic isolation.

In summary, people put blocks under the jack for different reasons, but mainly for stability and load distribution. It’s a good practice to use blocks under the jack, as long as they are sturdy and large enough to support the weight of the RV or car.


Having the right jacking system is crucial for RVers to safely stabilize and level their motorhomes or trailers. In summary, RV jacks are complex systems with many types and operating mechanisms. Understanding the differences helps buyers select jacks tailored for their specific camper and camping needs. With quality jacks properly matched to the vehicle, owners gain stability, avoid tipping disasters, and enjoy leveled living spaces at each destination. Taking the time to learn about and invest in the right jacking system pays dividends for years out on the road.
