9 Stabilizing Gear to Keep a Parked Motorhome from Swaying

Step inside a parked motorhome, take three paces, and you will likely feel the entire rig rock like a boat on a choppy lake. This annoying, persistent sway is more than just a nuisance; it strains your chassis and ruins a good night’s sleep. Fortunately, equipping your mobile home with the right stabilizing gear can turn a shaky suspension into a rock-solid foundation.

Understanding Why Parked Motorhomes Sway

Let’s look at the basic physics of your rig. Motorhomes and travel trailers are designed to travel down highways, which means they ride on rubber tires and highly flexible suspension systems. When you park, those same leaf springs, coils, and rubber tires remain active, transferring every step you take inside directly into a swinging motion.

There is a massive difference between leveling a rig and stabilizing it. Leveling simply ensures your refrigerator operates correctly and your water drains properly. Stabilizing, on the other hand, dampens the movement of the suspension so that wind, footsteps, and shifting weight do not cause the cabin to pitch and roll.

External factors also play a major role in how much your home moves. High winds pushing against the flat sides of a motorhome act like a sail, while extended slide-outs shift the center of gravity outward. Understanding these leverage points helps you place your stabilizing gear where it will do the most good.

Wheel Stabilizer – BAL X-Chock Tire Locking Clutch

Standard wedge chocks stop a tire from rolling, but they do nothing to stop the slight forward-and-backward tire rotation that causes interior cabin rock. A specialized wheel stabilizer bridges the gap between tandem tires to lock them in place. By halting this micro-rotation, you eliminate a major source of annoying park sway at the ground level.

The BAL X-Chock Tire Locking Clutch works by applying opposing force to the tandem tires on dual-axle rigs. It features a heavy-duty scissor mechanism that expands outward, pressing firmly against both tires simultaneously. The included plated ratchet wrench allows you to easily snug the metal chocks into place without breaking a sweat.

Before buying, make sure to measure the distance between your tandem tires. This particular model fits spacing from 1-3/8 inches to 10 inches, making it incredibly versatile for most standard dual-axle travel trailers. Always remember to remove these chocks before pulling out of your campsite, as driving over them will damage both the tool and your tires.

• Best for: Owners of tandem-axle travel trailers and fifth wheels seeking to eliminate tire-rotation bounce.
• Not for: Single-axle trailers, Class B camper vans, or motorhomes with wide axle spacing exceeding 10 inches.

Scissor Jack – Libra 5000lb RV Scissor Jack Set

When your built-in stabilizers cannot handle the load, auxiliary scissor jacks step in to take the weight off your suspension. They connect the RV’s metal frame directly to the ground, bypassing the bouncy springs and tires altogether. Without them, the ends of your trailer will sag and bounce whenever someone walks near the perimeter.

The Libra 5000lb RV Scissor Jack Set stands out due to its high-strength steel construction and wide bow-tie base plates. This broad base prevents the jack from sinking into soft turf or hot asphalt during summer trips. The kit includes a speed crank handle along with a 3/4-inch hex magnetic socket that fits standard power drills for rapid deployment.

Keep in mind that these jacks are strictly designed for stabilization, not lifting. Trying to lift your wheels completely off the ground to level your rig will strip the threads or bend the frame. Use them to apply firm upward pressure against the frame rails after the rig is already level.

• Best for: Travel trailers and lightweight fifth wheels needing sturdy, frame-mounted vertical stabilization.
• Not for: Heavy Class A diesel motorhomes or situations requiring structural wheel lifting.

Leveling Blocks – Camco Heavy Duty Leveling Blocks

Stabilizers work best when they do not have to extend very far. The longer a scissor jack or landing leg is extended, the more leverage it has to flex and wiggle. Leveling blocks solve this issue by raising the ground level under your tires and jacks, keeping your stabilizing equipment in its stiffest configuration.

The Camco Heavy Duty Leveling Blocks utilize an interlocking design that resembles giant toy building blocks. This modular system allows you to build custom-height ramps or solid platforms under your jack pads. Their bright yellow color ensures they remain highly visible so you never accidentally leave them behind in the grass.

When stacking these blocks, always build a pyramid shape if you go higher than two tiers. This distributes the massive weight of your rig safely and prevents the stack from tipping under load. Make sure to clean dirt and gravel out of the interlocking joints before storing them to preserve their structural integrity.

• Best for: Any RVer who frequently camps on uneven terrain or soft ground.
• Not for: Campers who exclusively visit paved, perfectly level RV resorts and have self-leveling hydraulic systems.

Step Stabilizer – Lippert SolidStep Stabilizer Kit

Every time someone steps into your RV, their entire body weight acts as a lever on the entry steps. This downward force causes a sudden, violent shake that vibrates through the entire living space. A dedicated step stabilizer transfers this sudden impact directly into the ground before it can shake the chassis.

The Lippert SolidStep Stabilizer Kit is engineered to mount directly to the bottom of Lippert SolidStep systems. It features adjustable legs with quick-release pins, allowing you to set the perfect height for various campsite terrains. This direct ground contact stops the entry steps from flexing and prevents the annoying springboard effect.

Ensure you verify your step brand and model before purchasing, as this kit is tailored specifically to Lippert systems. Additionally, clear any large rocks or debris from the landing area under the steps to ensure the stabilizer feet sit flat.

• Best for: Owners of Lippert SolidStep entry systems looking to stop the rig from shaking during entry and exit.
• Not for: Traditional hover-style pull-out metal steps or non-Lippert entry configurations.

Rubber Wheel Chock – MaxxHaul 50019 Heavy Duty

Safety and stability go hand in hand when parking a large motorhome. A heavy-duty wheel chock physically blocks tires from rolling on inclines while wedging them tightly to minimize micro-movements. Plastic chocks often slip on wet grass or asphalt, but heavy rubber chocks bite into the surface to hold the rig firm.

The MaxxHaul 50019 Heavy Duty Rubber Wheel Chock is constructed from durable, traction-grip rubber that stands up to weather and heavy loads. It features an integrated eyebolt handle, making it easy to carry or secure with a rope for quick removal. The ribbed surface pattern prevents tire slippage even in muddy or wet conditions.

These chocks are heavy and carry a distinct rubber smell when brand new, so storing them in an exterior bumper bay is recommended. Always place them tightly against the tire tread on both sides of the axle to ensure complete immobilization.

• Best for: Motorhomes, travel trailers, and heavy toy haulers parked on sloped or slick terrain.
• Not for: Ultralight campers where saving every single ounce of cargo weight is the top priority.

Jack Pad – RV SnapPad Xtra Permanent Jack Pads

Metal jack feet are prone to slipping on wet concrete and sinking deep into soft mud. Standard plastic pads work, but they require you to crawl under your dirty rig to place them every single time you set up camp. A permanent jack pad solves this hassle by remaining securely attached to your landing feet.

The RV SnapPad Xtra Permanent Jack Pads are made from recycled American tire rubber, offering incredible durability and vibration dampening. Once snapped onto your hydraulic jack feet, they stay on during travel, protecting the metal pads from rust and rock damage. The textured rubber bottom creates a massive, high-grip footprint that virtually eliminates slippage.

Before ordering, you must carefully measure your existing jack feet, as these pads are custom-sized for specific leveling systems. A tight fit is required for them to stay attached, so the installation process involves lubricating the lip and using the weight of the rig to snap them into place.

• Best for: Class A, B, and C motorhomes equipped with round hydraulic or electric leveling jack feet.
• Not for: Manual scissor jacks or tongue jacks that require small, square pad dimensions.

Stabilizer Bar – Lippert JT Strong-Arm Jack Kit

Even with jacks extended, standard landing legs can sway side-to-side due to the play in their telescoping segments. Stabilizer bars solve this by creating a rigid triangular truss system between your RV frame and the jack legs. This triangulation locks the suspension in place, neutralizing both lateral and longitudinal sway.

The Lippert JT Strong-Arm Jack Kit utilizes heavy-duty telescoping steel tubes that bolt directly to your existing jacks. Once your jacks are deployed, you simply tighten the T-handles on the stabilizer bars to lock the inner and outer tubes together. This simple action turns a flexible frame into a rock-solid structure.

This kit requires a one-time, hands-on installation that involves drilling into your frame and jack feet. It adds a minor step to your camp setup routine, as you must remember to loosen the T-handles before retracting your jacks to prevent bending the steel bars.

• Best for: Fifth-wheels and travel trailers parked for extended periods that experience persistent wind or interior movement.
• Not for: Casual weekend campers who prefer automated, push-button setups with zero manual intervention.

Slide-Out Support – Camco Heavy Duty Support Jack

Slide-outs add immense living space to your motorhome, but they also act as long levers hanging off the side of your chassis. Every time someone steps inside the slide-out, the weight shifts, causing the entire cabin to tip and sway. A slide-out support jack props up the outer edge, neutralizing this leverage and protecting your slide-out mechanism.

The Camco Heavy Duty Support Jack is made of durable steel and features a wide top saddle that safely cradles the slide-out frame. It adjusts easily from 19 to 47 inches using a simple screw-thread mechanism. This wide adjustment range makes it compatible with varying rig heights and uneven campsites.

Crucial warning: These supports must be used with extreme caution. If your RV tires lose air or your main leveling jacks sink into the ground, the entire weight of your coach will transfer to the slide-out supports, which can cause severe structural damage to your slide walls.

• Best for: Stationary RVers parked on concrete pads who want to protect their slide-out mechanisms from long-term sag.
• Not for: Campers parked on soft, shifting ground or those who do not regularly monitor their rig’s level.

Frame Stabilizer – Valterra 020106 RV Stabilizer

When permanent stabilizers are not enough, a portable frame stabilizer can fill the gaps in your system. Placing support directly under the frame rail near high-traffic areas, like the entry door or rear kitchen, absorbs local bounce before it travels through the rest of the coach. It acts as an adjustable pillar that you can position exactly where you need it most.

The Valterra 020106 RV Stabilizer is a universal system that utilizes a heavy-duty ratchet strap to pull two steel leg brackets tight against the frame. This design creates an immediate, rigid bridge between the chassis and the ground. It folds down flat for easy storage in your exterior compartments.

Setting this up requires crawling under the edge of your rig to hook the brackets onto the frame rails and tighten the ratchet strap. It works best on solid ground, so you may need to place a wooden block or leveling pad beneath the feet on soft turf.

• Best for: Budget-conscious RVers looking for a highly portable, non-permanent way to cure mid-coach bouncing.
• Not for: Individuals with limited mobility who cannot safely crawl or bend down to adjust under-chassis equipment.

How to Properly Position Your Stabilizing Gear

An organized, step-by-step approach is essential when setting up your stabilizing system. Always level your motorhome completely before deploying any stabilizing gear. Trying to level your rig using stabilizers can bend the stabilizer arms, twist your chassis, or crack your windshield.

Once the rig is level, drop your main leveling jacks or scissor jacks onto solid pads. Keep the extension of your stabilizers as short as possible by stacking leveling blocks underneath them. A short, thick stack of blocks with a half-extended jack is vastly more stable than a fully extended jack stretching to its physical limit.

Finally, place your wheel chocks, step stabilizers, and any under-frame supports. Target the high-leverage areas of your coach, such as the space directly beneath the entry steps and near the rear bumper. This systematic approach ensures every piece of gear works in harmony to lock down your mobile home.

Tips for Maintaining Your RV Stabilizing System

Keeping your stabilizing gear clean is the easiest way to prevent mechanical failures. Road grime, salt, and dust act as abrasive sandpaper on the threaded screws of scissor jacks and slide supports. Regularly spray these moving metal parts with a high-quality dry silicone lubricant, as wet grease will attract dirt and clog the threads.

Regularly inspect the welds, bolts, and rubber components of your stabilizing system. Check rubber wheel chocks for signs of dry rot and ensure your jack pads have not cracked from resting on sharp rocks. Tighten any loose mounting bolts on your frame-mounted stabilizers before hitting the road.

Proper storage is just as important as on-site maintenance. Store your blocks, jacks, and straps in clean, dry bays to prevent rust and mildew from taking hold. Shake off any mud, grass, or water before packing your gear away to keep your storage compartments clean and dry.

Eliminating the frustrating sway in a parked motorhome transforms your living space from a shaky trailer into a solid, comfortable home. By selecting the right combination of wheel chocks, frame stabilizers, and jack pads, you can enjoy peaceful nights and steady mornings. Invest in proper stabilizing gear today and experience the true comfort of a rock-solid mobile lifestyle.
