10 Essential Leveling And Stabilizing Kits For Full-Time RVers

Few things ruin the peace of a beautiful campsite faster than a cabinet door swinging open on its own or a shower that refuses to drain. Setting up an RV for long-term living requires transforming a rolling box on suspension into a solid, motionless home. Investing in the right leveling and stabilizing tools is the single best way to protect your appliances, preserve your slide-outs, and ensure a good night’s sleep.

Understanding RV Leveling vs. Stabilizing Systems

Leveling and stabilizing are two entirely different tasks, and confusing them is a quick way to damage an RV frame. Leveling is the act of bringing the rig parallel to the horizon, both front-to-back and side-to-side. This step is critical for comfort, proper drainage, and the operation of absorption refrigerators, which rely on gravity to circulate cooling fluids.

Stabilizing, on the other hand, is about eliminating the bounce and sway caused by suspension travel and wind. Stabilizers are designed to support a level rig and stop it from wiggling when people walk inside. They are not built to lift weight; attempting to level an RV using only stabilizing jacks can warp the chassis or strip the jack mechanisms entirely.

To achieve a rock-solid foundation, a full-time setup requires a combination of both systems. Heavy-duty blocks or curved levelers handle the heavy lifting, while stabilizers, chocks, and pads lock everything into place.

Curved Leveler – Andersen Hitches 3604 Camper Leveler

   _____ (Leveler)   /                 /  O    ____  <-- Drive wheel up the curve [_____________] <-- Chock locks it in place 

Curved levelers simplify the tedious process of side-to-side leveling on uneven campsites. Instead of guessing how many blocks to stack and repeatedly driving on and off them, these ramp-style levelers allow for precise adjustments. The rolling design lets the driver pull forward or back up until the rig is perfectly level, saving time and reducing stress.

The Andersen Hitches 3604 Camper Leveler stands out for its heavy-duty construction and intuitive design. Molded from high-density, durable polymers, this system provides up to four inches of lift and can support rigs weighing up to 30,000 pounds. The kit includes the curved leveler itself and a matching wheel chock that wedges underneath once the correct height is reached.

• Weight Capacity: Up to 30,000 lbs
• Lift Height: 1/2 inch to 4 inches
• Material: Heavy-duty nylon polymer
• Compatible Uses: Dual-axle travel trailers, fifth wheels, and single-axle trailers

Before buying, measure the distance between the tandem tires. If the tires are closer than three inches, the levelers may need to be trimmed by about an inch to fit between the wheels. They also require relatively firm ground to prevent the plastic from slipping or sinking during setup.

This kit is ideal for travel trailer and fifth-wheel owners who want a fast, one-person leveling solution. It is not suitable for large Class A motorhomes, which generally require hydraulic leveling jacks or wider wood and plastic block systems.

Leveling Blocks – Camco Heavy Duty Leveling Blocks

Leveling blocks are the Swiss Army knife of RV site setup. They stack together like interlocking plastic bricks, allowing the user to build custom ramps under tires or solid platforms under stabilizer jacks. By raising the height of the ground under jack feet, these blocks reduce the distance jacks must extend, which inherently increases overall stability.

The Camco Heavy Duty Leveling Blocks are a staple for full-time travelers because of their reinforced structure and high-visibility yellow design. They feature a solid bottom grid that resists sinking into soft soil or sand, a common failure point for cheaper, hollow-core blocks. The integrated carrying handle makes them easy to pack, stack, and store in tight basement compartments.

• Pack Size: 10 blocks per pack
• Material: UV-stabilized resin
• Design: Interlocking puzzle-style with a solid bottom
• Compatible Uses: Under tires, scissor jacks, tongue jacks, and hydraulic levelers

When stacking these blocks, always build a pyramid shape rather than a straight vertical column. A straight stack of blocks can slide or crack under the lateral forces of a rolling tire. Over time, UV exposure will degrade plastic, so keeping them clean and stored out of direct sunlight when not in use is key to their longevity.

These blocks are an essential purchase for every RVer, regardless of rig size. They are perfect for budget-conscious travelers and those who frequently camp on grass, gravel, or dirt. However, they are not a good fit for those who prefer automated setups and dislike manual labor.

Wheel Chock – BAL X-Chock Wheel Stabilizer

Traditional ground chocks prevent a trailer from rolling, but they do nothing to stop the front-to-back rocking motion caused by walking inside the coach. Tandem-axle trailers are prone to this movement because the tires act as pivot points. A specialized chock that fits between the tires is required to lock the suspension in place.

The BAL X-Chock Wheel Stabilizer works by applying outward pressure against both tires on a tandem axle. This scissor-action design locks the wheels in place, virtually eliminating the forward and backward movement of the trailer. Constructed from rust-resistant plated steel, it features a textured surface that grips the tire tread without causing damage.

• Adjustment Range: 1-3/8 inches to 10 inches
• Material: Zinc-plated heavy-duty steel
• Inclusions: Hand wrench (can be used with a drill adapter)
• Compatible Uses: Dual-axle travel trailers and fifth wheels

A critical safety rule is to always install ground chocks before unhitching, and only apply the X-Chocks after the trailer is disconnected and rough-leveled. Conversely, always remove the X-Chocks before hitching up to tow; driving with them installed can damage both the chocks and the trailer’s suspension.

This product is an absolute necessity for full-time tandem-axle trailer owners who want to eliminate annoying interior sway. It is useless for single-axle trailers, motorhomes, or rigs with wide-spread axle designs that exceed a ten-inch tire gap.

Scissor Jack – Maxxhaul 70115 Steel Scissor Jack

Many travel trailers come equipped with lightweight, factory-installed stabilizer jacks that bow under moderate wind or movement. Upgrading to a heavier, aftermarket scissor jack provides a stiffer point of contact with the ground. This upgrade reduces frame flex, especially on longer trailers with significant overhangs.

The Maxxhaul 70115 Steel Scissor Jack is a heavy-duty replacement option built to handle demanding use. Made from stamped steel with a black rust-resistant coating, each jack in this pair is rated to support 5,000 pounds. The large bow-tie base plate offers excellent stability on soft surfaces, preventing the jack from tipping or shifting.

• Weight Capacity: 5,000 lbs per jack
• Lift Range: 4 inches to 24 inches
• Material: Heavy-duty powder-coated steel
• Mounting: Bolt-on or weld-on installation

Keep the worm gear clean and lubricated with dry graphite spray rather than wet grease, which attracts road grime and dirt. Using a cordless drill with a 3/4-inch socket adapter speeds up the deployment process significantly, though the user must take care not to over-torque the jacks at the end of their travel.

These jacks are perfect for DIYers looking to upgrade weak factory stabilizers on travel trailers and toy haulers. They are not designed for lifting tires off the ground during tire changes, nor are they suitable for heavy Class A motorhomes.

Tripod Stabilizer – BAL 25067 King Pin Jack

Fifth-wheel trailers feature a massive front overhang that houses the main bedroom suite. Because this section sits high above the ground and is supported only by the landing gear, it acts as a giant lever arm. Every movement in the bedroom causes the entire trailer to shake, making front-end stabilization a high priority.

The BAL 25067 King Pin Jack is a tripod stabilizer that mounts directly under the trailer’s kingpin. By adding a third point of contact in a triangular configuration, it channels lateral forces directly into the ground. The heavy-gauge steel tubing and adjustable threaded screw pad allow for fine-tuned tensioning once set up.

• Height Range: 34 inches to 51 inches
• Material: High-grade steel with a rust-inhibiting finish
• Footprint: Large triangular base plates to prevent sinking
• Compatible Uses: Standard fifth-wheel kingpin hitches

This tripod is bulky and takes up a notable amount of space in storage compartments. Setting it up requires lifting the heavy steel frame into position under the hitch, which can be awkward for a single operator. Regular lubrication of the cup and screw assembly is required to prevent binding over time.

This tool is a must-have for full-time fifth-wheelers who spend extended periods parked in one spot and want to eliminate bedroom bounce. It is not suitable for bumper-pull travel trailers or motorhomes.

Jack Pad – RV SnapPad Xtra Multi-Pack

Standard metal jack feet are relatively small and can easily sink into soft asphalt, mud, or gravel. Traditional solution involves placing loose wood blocks or plastic pads under the jacks during every single setup. Permanent jack pads solve this chore by snapping directly onto the existing metal feet, staying attached during transit.

The RV SnapPad Xtra Multi-Pack is made from recycled utility-grade rubber tires, providing a durable, slip-resistant barrier. They cushion the impact of metal jacks on concrete, prevent rust on the metal feet, and increase the footprint of the jack by up to 60 percent. This extra surface area distributes the rig’s weight more evenly, preventing sinking.

• Material: Recycled heavy-duty tire rubber
• Footprint Increase: Up to 60% larger surface area
• Installation: Permanent snap-on (one-time installation)
• Compatible Uses: 9-inch round landing feet (LCI, Equalizer, and others)

Before purchasing, measure the shape and diameter of the existing jack feet precisely, as SnapPads are engineered to tight tolerances for specific brands. Installing them requires soapy water as a lubricant and the weight of the RV to press the feet down into the pads until they snap into place.

These pads are a premium, convenient upgrade for motorhomes and fifth wheels with automatic hydraulic leveling systems. They are not designed for manual scissor jacks or small, non-standard leveling feet.

Electronic Level – LogicBlue LevelMatePRO+

Traditional bubble levels require looking at the side of the trailer, adjusting blocks, and jumping back into the tow vehicle to check the progress. This process often takes multiple attempts, especially on highly uneven terrain. An electronic leveling system brings real-time, digital precision directly to a smartphone screen.

The LogicBlue LevelMatePRO+ is a wireless vehicle leveling system that mounts inside the RV. It calculates the exact height required for each wheel to reach a perfect level, displaying the measurements in inches or centimeters on a phone. The “+” version features a micro-USB power port alongside a backup battery, ensuring the unit is always powered.

• Connectivity: Bluetooth (long-range)
• Power Source: Micro-USB or CR2032 battery
• Accuracy: Within 0.1 degrees
• Compatible Uses: Travel trailers, fifth wheels, and drive-on motorhomes

[Phone Screen: LevelMatePRO App] ----------------------------- Left Rear:  +1.50"  [Raise] Right Rear:  0.00"  [Level] ----------------------------- 

The initial calibration must be done on a perfectly level surface, as the unit memorizes this baseline to make all future calculations. If the unit is mounted securely on a wall that flexes, the readings will drift over time.

This device is ideal for solo travelers and those who boondock frequently on rough, uneven public lands. It is less necessary for those who only stay in paved, level RV resorts.

Electric Tongue Jack – Husky 81077 Brute Power Jack

Using a manual hand-crank to lift the tongue of a heavy travel trailer is exhausting, especially after a long day of driving. An electric tongue jack automates this process, handling the heavy lifting of the trailer tongue and the tension of weight-distribution hitch bars with the push of a button.

The Husky 81077 Brute Power Jack features a high-efficiency ball-screw design that reduces friction compared to standard Acme thread screws. This design translates to less wear on the motor, quieter operation, and faster lift speeds. With a 4,500-pound capacity, it handles heavy tongue weights without straining the RV’s 12V battery system.

• Lift Capacity: 4,500 lbs
• Travel Distance: 18 inches of full travel
• Lighting: 3-sided LED light system
• Drive Type: Low-friction ball-screw mechanism

The jack draws significant power, so it must be wired directly to a healthy house battery using heavy-gauge wire. It is also wise to keep the manual override crank handy and know how to access the port on top of the housing in case of an electrical failure.

This jack is a great upgrade for anyone towing a bumper-pull travel trailer or toy hauler over 24 feet. It does not apply to fifth-wheel trailers or motorhomes.

Slide-Out Support – Camco Eaz-Lift 48866 Support

On older or exceptionally large slide-outs, the weight of the slide can cause the RV frame to lean slightly when extended. Over weeks or months in one location, this constant off-center load can strain the slide mechanism and wear out the seals. Slide-out supports provide temporary vertical relief to the outer edge of the slide box.

The Camco Eaz-Lift 48866 Support is made from heavy-duty steel and features a wide base plate for stability. The threaded screw top allows for fine height adjustments, while the soft polyurethane saddle protects the bottom frame of the slide-out from scratches.

• Weight Capacity: Up to 5,000 lbs per jack
• Height Adjustment: 19 inches to 47 inches
• Material: Heavy-duty powder-coated steel
• Saddle Design: Protective non-marring top pad

   [RV Wall] ======[ Slide-Out Box ]======                       ||                       || <-- Place Support Here                       ||                      /    <-- Wide Base on Solid Ground 

Crucial Warning: These supports must only be used on completely stable, leveled rigs. If the RV’s main tires lose pressure, sink into the ground, or settle over time, the weight of the entire coach will transfer to the slide-out support, which can crush the slide-out frame or ruin the rack-and-pinion gear system.

These supports are suitable for stationary, long-term full-timers with older, heavy slide-outs parked on solid concrete pads. They are not recommended for weekend campers, soft-ground camping, or rigs with modern hydraulic slide systems.

Step Stabilizer – Lippert SolidStep Stabilizer Kit

Modern fold-down RV steps provide a solid feel, but they can still flex and bounce when a heavy load is applied. This “diving board” effect transfers movement directly into the RV frame, shaking the entire coach whenever someone enters or exits. Supporting the step from underneath eliminates this nuisance.

The Lippert SolidStep Stabilizer Kit mounts directly to the underside of Lippert SolidStep systems. It features dual adjustable legs that extend to meet the ground, creating a solid truss that stops the steps from flexing. The quick-release pins allow for fast adjustment on uneven terrain like gravel or sloped campsites.

• Compatibility: Fits Lippert SolidStep models
• Material: Powder-coated steel
• Adjustability: Multi-position pin lock
• Installation: Bolt-on mounting under the step tread

Keep the adjustment pins clean and free of mud to prevent them from seizing. If camping on soft ground, place a small plastic block under the stabilizer feet to prevent them from sinking and losing their support tension.

This kit is perfect for RVers with high-clearance entryways who want to stop the coach from rocking during daily foot traffic. It will not work on traditional pull-out steel steps that retract into the chassis.

Safety Tips for Leveling Your Rig on Uneven Ground

Leveling an RV on a steep incline requires strict adherence to a specific order of operations to prevent runaway accidents. Always level side-to-side first while the trailer is still securely hitched to the tow vehicle. Only after the tires are chocked on both sides should you disconnect the hitch and proceed with front-to-back leveling.

Step 1: Level Side-to-Side (Hitched) -> Step 2: Chock Wheels -> Step 3: Unhitch -> Step 4: Level Front-to-Back 

Never lift the wheels of a motorized coach or a trailer completely off the ground to achieve a level state. RV brakes and parking gears work through the tires; if the drive wheels are suspended in the air, the entire rig can slide off the jacks with catastrophic results. If a site is so unlevel that a tire must leave the ground, find a different site or use robust, wide ramp blocks to support the tire’s weight.

Finally, monitor the ground conditions throughout your stay. Heavy rain can turn firm soil into soft mud, causing jacks to sink and the rig to shift. Check your bubble levels or electronic monitoring app once a week during long-term stays, and make minor adjustments to your jacks to compensate for natural ground settling.

Conclusion

Achieving a stable, level foundation is the quiet cornerstone of successful full-time RV living. By investing in quality leveling blocks, robust chocks, and proper stabilizers, you protect your RV’s slide mechanisms, keep your appliances running safely, and eliminate the constant swaying that makes a mobile rig feel temporary. Take the time to set up your foundation correctly at every site, and your home on wheels will reward you with years of reliable, rattle-free comfort.
