Andersen Camper Leveler: For Fast Precise Leveling

The Andersen Camper Leveler is the gold standard for those who value speed and infinite adjustability. Its curved design allows you to drive up until the rig is perfectly level, then simply slide the included chock under the edge to lock it in place. It eliminates the “trial and error” guesswork of stacking plastic blocks, making it ideal for solo travelers or those who want to minimize setup time.

If you are tired of backing up, checking a level, moving forward, and repeating the cycle, this is the solution. It works best on firm, packed ground where the base can grip effectively. Because it provides a continuous surface rather than a stepped one, it feels more secure under the tire.

However, be aware that this system requires enough clearance to slide the chock under the wheel once leveled. If your tires are very close together or your rig has minimal ground clearance, verify the fit before heading out. For most standard travel trailers, the Andersen is the most intuitive and satisfying way to achieve a perfect level.

Camco FasTen Leveling Blocks: Best Overall Value

Camco FasTen blocks represent the classic “Lego-style” approach to leveling that has served the RV community for decades. These interlocking blocks are lightweight, affordable, and incredibly versatile, as they can be configured into a pyramid or a simple flat runway depending on how steep the site is. They are the utility player of your storage bay.

These blocks are particularly well-suited for soft ground, as they provide a wider footprint that prevents the tire from sinking into mud or sand. Because they are modular, you can tailor the height precisely to the specific slope of the campsite. It is a foolproof system that handles almost any terrain variation you might encounter.

The trade-off is the physical labor involved in stacking and aligning them, especially if you have to readjust. If you are budget-conscious and want a reliable, no-nonsense system that works on both asphalt and soft dirt, these are the best value you will find.

BAL Light Trailer Tire Leveler: For Single Axles

For owners of single-axle trailers or pop-up campers, the BAL Light Trailer Tire Leveler is a unique, highly effective piece of hardware. Instead of driving onto blocks, this device uses a scissor-jack mechanism to mechanically lift the tire by squeezing it from both sides. It is essentially a custom-fit lift for your specific wheel.

This method allows for incredible precision, as you can dial in the level using a wrench to raise or lower the trailer by fractions of an inch. It is an excellent choice for smaller, lighter rigs that do not have the mass to drive onto heavy plastic blocks easily. It also serves as a secondary locking mechanism, adding a layer of stability that loose blocks cannot provide.

The downside is that it is strictly for single-axle trailers and requires a bit of muscle to operate the screw-jack. If you have a tandem-axle trailer, this is not the right tool for you. For the right owner, however, it offers a level of control and security that is unmatched by simple ramps.

Lynx Levelers: The Original Interlocking Block

Lynx Levelers are the industry benchmark for interlocking plastic blocks, known for their durability and high-visibility color. They are engineered to handle the immense weight of larger travel trailers and fifth wheels without cracking or deforming. When stacked in a pyramid, they provide a stable, wide base that gives the driver confidence when pulling onto them.

These blocks are ideal for those who prefer a standardized system with a proven track record. They interlock tightly, reducing the risk of shifting when pulling the rig into position. They also integrate seamlessly with optional caps and accessories, allowing you to create a “flat” top surface that saves wear and tear on your tires.

While they are slightly more expensive than generic store-brand blocks, the longevity of the plastic usually justifies the cost. If you want a “buy it once, keep it forever” solution, Lynx Levelers are the clear choice. Their reputation is built on reliability, making them a safe bet for any campsite.

Beech Lane Camper Leveler: A Heavy-Duty Ramp

The Beech Lane Camper Leveler is the heavy-duty evolution of the ramp-style system. It features a robust, reinforced design that can handle significantly higher weight ratings than standard plastic levelers, making it an excellent match for larger, heavier travel trailers. The grippy texture ensures that the tire stays exactly where you place it, even on loose gravel.

This leveler is perfect for the traveler who is frustrated by the flexibility of thinner plastic ramps. It provides a solid, uncompromising platform that feels secure the moment the trailer stops moving. Because of the heavy-duty construction, it is less prone to cracking under high heat or extreme cold.

It is worth noting that this is a heavier unit, taking up more space in your storage compartment. However, for those with heavier rigs who refuse to compromise on stability, the added weight and size are a fair price to pay. It is a high-performance tool for those who take their campsite setup seriously.

Valterra Stackers: The Heavy-Rig Solution

Valterra Stackers are designed specifically for the big rigs that require extra support and surface area. These are wider and thicker than standard leveling blocks, providing a significantly larger footprint to prevent sinkage on uneven or damp ground. They are the go-to for fifth wheels and larger motorhomes that put significant pressure on the ground.

The primary advantage here is the stability afforded by the wider design; there is less “tip” risk when driving a heavy rig up onto a stack. They also feature a convenient storage strap system, which helps keep them organized in a bay that is likely already filled with other gear. They prioritize structural integrity above all else.

These are not the most compact option, so they are best suited for rigs with large pass-through storage. If you are struggling with a heavy, top-heavy trailer that makes standard blocks feel unstable, transitioning to Valterra Stackers will provide an immediate and noticeable improvement in your setup process.

Ramp vs. Block Levelers: Which Style Is for You?

Choosing between a ramp and a block system usually comes down to your rig’s weight and your personal patience level. Ramps, like the Andersen or Beech Lane, offer a continuous, smooth adjustment that makes leveling a one-pass process. They are incredibly fast but require a bit more attention to clearance and tire positioning.

Blocks, conversely, offer a modular, “any-shape-you-need” flexibility. If you are camping on rocky, uneven terrain where a ramp might tip or slide, blocks can be configured into a custom stack that fits the ground perfectly. They are the Swiss Army knife of leveling.

Consider your storage space as well. Ramps are often bulkier and harder to pack efficiently, whereas blocks can be stacked in any corner. If you are in a smaller van conversion or a compact travel trailer, space-saving might dictate your choice more than ease of use.

How to Safely Level Your Rig on a Steep Slope

Leveling on a steep slope requires more than just the right gear; it requires a disciplined safety protocol. Always place your levelers on the ground first, then pull the trailer up onto them—never try to “force” the rig onto them if the slope is so steep that you lose traction. Traction is the enemy on a steep pad, so ensure your leveling surface has high-friction contact.

Once the rig is positioned, always engage your parking brake and put the transmission in park before exiting the vehicle to check your level. If you are using a travel trailer, ensure the tongue jack is lowered to the appropriate leveler height before you start unhitching. Moving too quickly here is the most common cause of trailer runaway.

Lastly, never rely solely on your levelers to hold the rig’s weight for an extended stay. Once the rig is level, use your stabilizers—or preferably, jack stands if the site is exceptionally steep—to take the weight off the suspension. This protects your frame and prevents the rig from shifting as you move inside.

Don’t Forget Chocks Jacks and Stabilizers

A level rig is only as good as its foundation, and that foundation requires proper chocking. No matter how good your leveling blocks are, they do not replace the need for wheel chocks on the opposite side of the trailer. Chocks prevent the trailer from rolling backward or forward, which is a critical safety factor when you are dealing with an incline.

Stabilizers are often confused with leveling jacks, but they serve two very different purposes. Stabilizers are meant only to stop the “rocking” motion of the rig, not to lift it. If you try to use stabilizers to level your rig, you risk bending the mounting brackets or damaging the frame entirely.

Always carry a set of heavy-duty rubber chocks and a collection of hardwood or plastic jack pads. Even if your campsite pad is concrete, placing a pad under your stabilizers prevents the metal feet from cracking the asphalt or sinking into soft soil. It is a small investment that preserves your gear for years to come.

Leveling Shim FAQs: Your Top Questions Answered

• Can I leave my rig on leveling blocks for weeks at a time? Yes, provided the blocks are rated for your rig’s weight and are set on a stable, flat surface. However, always ensure the weight is distributed properly and the blocks are not showing signs of stress.
• Do I need to level side-to-side and front-to-back? Always level side-to-side first using your ramps or blocks, then use the trailer’s tongue jack or the motorhome’s leveling jacks to finalize the front-to-back level.
• What if my leveling blocks sink into the dirt? Use a wider base plate or a piece of plywood underneath the blocks to distribute the weight across a larger surface area. This is a common requirement on sandy or muddy sites.
• Is it better to use a bubble level or a digital one? A standard bubble level mounted to the side of the rig is usually sufficient, but digital levels on your smartphone can offer more precision if you are particularly sensitive to slope.

Mastering the art of the level is a rite of passage for any mobile dweller, and it is the single most effective way to ensure your living space feels like a true home. While no leveling system can fix an excessively dangerous slope, the right equipment will save your sanity and protect your rig’s vital systems. Invest in gear that matches your trailer’s weight and your own patience level, and you will find that even the most uneven sites become manageable in no time.
