Choosing a stabilizer involves balancing your RV’s specific entry height against how much weight you need to support. Most options focus on either a permanent mount under the steps or a portable jack you place manually. The main difference lies in whether you prefer a hands-free folding design or a simple, adjustable post.
Best overall: Lippert Solid Stance offers a secure, permanent dual-leg design that stays attached to your steps for easy storage and handles uneven ground with its four adjustable angles.
Most reliable support: Camco Save-A-Step Brace uses heavy-gauge steel and a high load rating to provide a rock-solid, fixed-height support that’s built for long-term durability under heavy use.
Best for tall steps: **Stromberg Carlson JSS-85** provides the longest reach for coaches with higher entry points, ensuring you can stabilize steps that sit further from the ground than standard models.
This guide is for RV owners who want to stop their steps from rocking, sagging, or creating a safety hazard when entering and exiting their coach.

1. Lippert Solid Stance RV Step Stabilizer Kit
Best for: Owners of Lippert-equipped travel trailers and motorhomes.
This stabilizer attaches directly to your entry steps, meaning you don’t have to move it every time you arrive at a campsite. The dual-leg design provides a wide footprint, which helps keep the steps from bouncing or swaying while you move between the ground and your RV. Because it stays in place, setup is fast and requires no extra tools once installed.
The individually adjustable legs allow you to adapt to sloped or uneven ground without needing to carry extra blocks or shims. You can adjust the height between 5” and 14” to ensure a level entry regardless of the campsite grade. If you’re parked on a steep incline, use the four distinct adjustment angles to maintain a solid foundation.
Most users finish the initial setup in 15-20 minutes. Avoid the mistake of forcing the legs into a locked position before checking your step configuration; if you have a Lippert double or triple Steel Radius or Alumi-Tread step, the kit is a direct fit. If you’re using a competitor assembly, verify the bracket clearance first to prevent binding. Once attached, the unit folds away with the stairs, saving you the effort of dismantling the system during departure.
Pros
- Stays attached for easy storage
- Four individual adjustment angles
- Handles uneven ground effectively
Cons
- Requires specific step compatibility
- More complex initial installation
2. Camco Camper/RV Save-A-Step Brace
Best for: Those wanting a high-weight capacity support.
This brace is built from heavy-gauge steel and features a 3/4″ solid metal screw thread for height adjustments. It acts as a load-bearing column that sits under your bottom step to prevent sagging. With a 1,000 lb load rating, it’s one of the most robust options for supporting heavy foot traffic.
The unit is designed to swing up and store under your steps when you’re ready to hit the road. This keeps your storage space clear and ensures the brace is always ready for your next stop.
Check your step height before buying. The brace adjusts from 7 5/8″ to 14″. If your bottom step sits higher than 14″ from the ground, the brace won’t reach to provide support. It’s intended for use on stable, level surfaces. If you frequently camp on loose or extremely soft ground, the brace may sink rather than stabilize, rendering it ineffective. In those cases, use a wide, flat leveling block under the base to distribute the weight.
Pros
- High 1,000 lb weight rating
- Heavy-gauge steel construction
- Folds away for storage
Cons
- Requires firm, level ground
- Limited to single-point support
- Doesn’t reach steps higher than 14″
3. STROMBERG CARLSON JSS-7 RV Trailer Camper Stabil-Step Adjusts 8″
Best for: Standard height adjustments for smaller steps.
The JSS-7 is a straightforward, removable support that helps eliminate the sway common in many factory-installed RV steps. It features a round tube design with a square base, which provides a stable point of contact for the bottom step. By taking the weight off the step’s hinge and frame, it helps extend the lifespan of your entry mechanism.
Because it’s removable, it’s easy to tuck away in a storage bay once you’re packed up to leave. It’s rated to support up to 750 pounds, which is plenty for most travelers. If your steps require a height beyond 13.5 inches, you’ll need to look at a longer model to ensure the stabilizer can reach the ground.
Measure the distance from the ground to the bottom of your retracted step. If the gap is less than 8 inches, this model will be too tall to fit underneath. If the gap is between 8 and 13.5 inches, this support will effectively bridge the distance and stabilize the assembly.
Many owners make the mistake of leaving the support deployed while the steps are folded. Always remove the unit before travel to avoid damaging the step mechanism or the support itself.
Pros
- Simple, removable design
- Protects hinge mechanisms
- Lightweight and portable
Cons
- Lower height range than others
- Not a permanent mount
4. Quick Products QP-JSS-4 RV Step Stabilizer
Best for: Low-clearance entry steps.
This compact stabilizer is specifically designed for steps that sit closer to the ground, with an adjustable range of 4.75 to 7.75 inches. It eliminates the drooping, sagging, rocking, and swaying that make entering an RV feel unstable. By creating a firm base, it prevents mechanical fatigue and extends the overall life of your step unit.
Use this tool only on hard, level surfaces. If your campsite is soft dirt or gravel, the stabilizer may sink or tilt, rendering it ineffective. It supports up to 750 pounds, which covers most standard entry needs. If your steps are mounted higher than 7.75 inches off the ground, this model will be too short to reach the surface. Always measure the gap between your bottom step and the ground before purchasing to ensure a proper fit.
Pros
- Excellent for low-clearance steps
- Simple, universal fit
- Sturdy 750 lb capacity
Cons
- Short height range
- Requires hard, level ground for safety
5. RV Step Stabilizer – 4-8in Adjustable Height Step Tool
Best for: Users who want a quick, portable fix.
This Dumble stabilizer is designed for simplicity. You place it under your steps and spin the top counterclockwise until the metal top meets the bottom of your stair tread. This creates a solid support that prevents the coach from swaying as you walk in or out.
It features a 1,000 lb weight rating and is built with a 3/4-inch solid metal screw thread. Because it’s portable, it’s easy to move between different vehicles or stow away in a small area.
If your steps are bowing, this tool provides the necessary pressure to prevent further damage and extend their lifespan. Always ensure you’re using this on a flat surface to maintain the stability of the support column. If the ground is soft or sloped, the stabilizer will shift, causing the steps to remain unstable. You can adjust the height from 4 to 8 inches to accommodate most camper, RV, or motorhome models.
Pros
- High 1,000 lb weight rating
- Simple, tool-free setup
- Easy to store
Cons
- Manual adjustment required
- Not for uneven surfaces
6. Camco Self Stor RV Step Brace
Best for: Durability and long-term use.
The Self Stor is a heavy-duty option from Camco that prevents premature wear on your RV entry. It features a 1,000 lb weight rating and uses a 3/4-inch solid metal screw thread to dial in the exact height required. This steel construction ensures the unit stands up to the rigors of frequent travel and harsh outdoor exposure.
If your step height sits between 8.5 inches and 14 inches, this brace will fit your rig. Measure the distance from the ground to the underside of your bottom step before purchasing. If your clearance is less than 8.5 inches, this model won’t retract or fit properly.
A key feature is that it mounts directly under your entry steps. When you’re ready to move, it swings up and stores securely beneath the step. You never have to worry about losing the stabilizer or finding extra storage space inside your RV.
However, because it mounts permanently, you must ensure your step design allows for the bracket attachment. If your steps have a unique folding mechanism that interferes with the mounting plate, you’ll need a removable alternative.
Pros
- Mounts permanently under steps
- High 1,000 lb weight rating
- Durable steel construction
Cons
- Heavier than removable poles
- Needs specific mounting space
7. RV Step Stabilizer
Best for: Wide-ranging height needs.
This stabilizer offers a unique adjustment range, starting as low as 2.8 inches and reaching up to 11.4 inches. This versatility allows you to adapt to uneven campsite terrain or varying vehicle heights. If your campsite features a significant slope, this range ensures your steps remain level and secure.
The unit resists corrosion, making it a reliable choice for coastal regions or wet climates where metal parts often degrade. Because it requires no tools for assembly, you can deploy it in seconds upon arrival. Simply adjust the height to meet the bottom step and lock it in place to eliminate wobbling.
If you notice your steps flexing or shifting underfoot, this stabilizer provides the necessary rigid support to prevent accidents. Use it whenever you’re parked on soft ground or gravel where standard steps lack a firm foundation. While it’s highly portable, remember that it’s designed for temporary use rather than a permanent structural fix.
Pros
- Very low starting height
- Corrosion-resistant material
- Tool-free installation
Cons
- Mid-range maximum height
- Portable, not fixed
8. Stromberg Carlson JSS-85 RV Trailer Camper Steps & Ladders Step
Best for: Tall RVs with high step heights.
If your RV sits high off the ground, the JSS-85 is the support you need. It adjusts from 8.5 inches up to 16 inches, giving you the extra reach required for taller trailers and coaches. By placing this support under your assembly, you take the load off your step tread, the carrying mechanism, and the frame. This simple adjustment prevents premature metal fatigue and lengthens the life of your entire entry system.
It features a rectangular base for better stability compared to round-base models. It’s fully removable and folds for easy storage, so you don’t have to leave it attached while traveling. If your step sits lower than 8.5 inches, this model won’t fit under the assembly. Always measure the distance from the bottom of your lowest step to the ground before ordering. If that measurement is less than 8.5 inches, this stabilizer will be too tall to function.
Pros
- Extra-long reach
- Stable rectangular base
- Folds for storage
- Supports up to 750 pounds
Cons
- Too tall for low steps
- Removable, not permanent
9. RV Step Stabilizer Kit
Best for: 5th wheel and travel trailer owners.
This kit is very similar to the Lippert Solid Stance, offering dual-leg support that attaches directly to your entry steps. It’s compatible with many double and triple step configurations, including steel radius and alumi-tread hybrid designs. The ability to adjust each leg individually makes it perfect for campsites where the ground isn’t perfectly flat.
If your campsite pad slopes, use the multiple adjustment angles to level the platform. If you encounter soft grass or gravel, the dual-leg design prevents the sinking that causes entry steps to sag. This protection is vital for maintaining the structural integrity of your bottom step.
Installation is straightforward, usually taking around 15 to 20 minutes to complete. Once attached, it stays with your steps, folding up when you’re ready to go. It’s a great way to eliminate bounce and protect your steps from sagging without needing to carry extra equipment.
Before purchasing, verify your step type. This stabilizer fits all double and triple Steel Radius Entry Steps and Alumi-Tread Hybrid Aluminum configurations. If you have a different step material, this kit won’t mount correctly.
Pros
- Dual-leg stability
- Stays attached during travel
- Handles uneven ground
Cons
- Requires specific step compatibility
- Longer initial setup
10. TonGass RV Step Brace Stabilizer Adjustable Length from 7 5/8″
Best for: Universal compatibility with most RVs.
The TonGass stabilizer is a reliable, heavy-duty brace that fits a wide variety of RV entry steps. It uses a thick, heavy-duty threaded rod to provide a solid load-bearing column. This helps stop the rocking motion that can be so annoying when you’re trying to enter or exit your camper.
It’s simple to install, adjust, and remove as needed, making it a flexible choice for many different RV owners. It handles up to 1,000 pounds, which is among the highest in its class. Because it’s a center-support brace, it works best when placed on a hard, level surface to ensure maximum stability.
If your campsite is soft or uneven, the brace will lose its load-bearing effectiveness. Always verify your ground condition before deployment. If the gap between your step and the ground is less than 7 5/8 inches or exceeds 14 inches, this specific model won’t fit. Measure this distance carefully while the RV is parked on level ground to avoid buying an incompatible tool.
Pros
- Universal fit
- High 1,000 lb weight rating
- Easy adjustment
Cons
- Requires level ground
- Not a permanent mount
How to Choose the Best RV Step Stabilizer Jack
Which type of stabilizer is better: permanent or portable?
Permanent stabilizers, like the Lippert Solid Stance, attach directly to your steps. They’re excellent because they fold away with the stairs, meaning you never have to find a place to pack them. These are best for owners who want a consistent, “set it and forget it” experience. Portable stabilizers, such as the Camco Save-A-Step, are flexible if you have multiple RVs or want to use the stabilizer in different spots. However, you must remember to pack them before you leave. If you’re prone to leaving things behind at the campsite, a permanent mount is the safer bet.
How do I measure for the correct height?
You need to measure the distance from the bottom of your lowest step tread to the ground when the steps are fully deployed. Be sure to measure while the RV is parked on a flat, level surface. If you choose a stabilizer that’s too short, you won’t be able to reach the ground to provide support. If it’s too tall, you won’t be able to fit it under the step. Always look at the adjustment range provided in the product data. If you camp on uneven ground, choose a model with a slightly wider adjustment range to accommodate those differences.
Does weight capacity actually matter for steps?
Yes, weight capacity is crucial because these stabilizers take the physical load off the RV’s door frame and step hinges. By supporting the weight of the person stepping on the stairs, they prevent the metal from bending.

Frequently Asked Questions
What happens if I use my stabilizer on soft ground?
Most step stabilizers are designed for hard, level surfaces. If used on soft ground, the base can sink, causing the steps to lose support. Place a solid pad, such as a wooden block or leveling board, under the base to distribute weight and maintain stability.
Does a stabilizer fix steps that are already sagging?
A stabilizer provides a support point to stop movement, but it cannot repair steps that are already bent or damaged. If your steps are currently sagging, you may need to replace the assembly before adding a stabilizer to ensure they are safe for use.
Are these stabilizers enough to support the whole step assembly?
Yes, these stabilizers act as a vertical pillar to transfer weight directly to the ground, taking the load off your RV’s hinges and sidewall. This significantly reduces stress on the mounting frame. Always check the load rating of your model to confirm it meets your requirements.
Is the simplest model on the list enough for my needs?
Portable stabilizers like the Dumble or TonGass models provide essential support to stop swaying without requiring a permanent mounting system. They offer the same structural benefits as complex systems, provided you have a level surface to place them on.
Conclusion
Once you’ve picked the right support, take a moment to test it on level ground before your next trip. You’ll find that a stable entrance makes a huge difference in how your camper feels. Don’t wait until you’re at the campsite; set it up in your driveway to get comfortable.
