Why Quality Leveling Blocks Are Non-Negotiable
Being level isn’t just a creature comfort; it’s a mechanical necessity for any RV. Your absorption refrigerator, which uses gravity and heat to circulate coolant, can be permanently damaged if operated off-level for extended periods. Water won’t drain correctly from your sinks and shower, and holding tank sensors will give you false readings. It even affects your sleep and overall sense of balance inside your own home.
Many new RVers are tempted to use scrap lumber they have lying around. This is a mistake. Wood splits under the immense pressure of an RV, rots when left on wet ground, and can easily slip, creating a serious safety hazard. It’s an unstable, unpredictable foundation for a multi-ton vehicle.
Purpose-built leveling blocks are engineered for this exact task. They are made from high-density, UV-resistant polymers that won’t crack or degrade in the elements. Their interlocking designs distribute weight evenly and create a wide, stable footprint that resists sinking into soft ground. Investing in a quality set isn’t about buying an accessory; it’s about ensuring the safety and proper function of your entire rig.
Andersen Camper Leveler: The Ultimate Fast Setup
The Andersen Leveler isn’t a block at all—it’s a curved plastic ramp. The concept is brilliantly simple: place the ramp under the low-side tire, drive forward until your level reads perfect, and slide the included chock under the high point of the ramp. That’s it. You’re done in under a minute.
The major advantage here is speed and infinite adjustment. Unlike stacking blocks, you aren’t limited to one-inch increments. You can achieve a precise level up to four inches of lift with zero guesswork. For solo travelers or anyone who hates the back-and-forth of traditional blocks, the Andersen system is a game-changer. It turns a frustrating chore into a simple, one-person job.
However, there are tradeoffs. The Andersen system works best on dual-axle trailers, where one leveler can be placed between the tires. On some surfaces, like wet grass or slick pavement, they can sometimes slip as you drive onto them. They’re also one of the more expensive options on the market. But for those who prioritize speed and precision above all else, many nomads swear they are worth every penny.
Camco FasTen Blocks: A Versatile, Classic Choice
Level your RV easily with these interlocking blocks for customizable height. The integrated handle makes carrying and storing the blocks simple and secure.
If you’ve spent any time in a campground, you’ve seen Camco’s iconic yellow (or orange) blocks. These interlocking "Lego-style" blocks are a staple in the RV world for good reason. They are lightweight, relatively inexpensive, and incredibly versatile. A standard 10-pack is easy to store and provides enough lift for most common campsite situations.
Their strength lies in their adaptability. You can build a small pyramid for a tire, use a single block under a stabilizer jack, or place one under your tongue jack on soft ground. The interlocking design makes them secure when stacked, and their open-grid construction helps shed mud and water. They are the multi-tool of the leveling world—not always the fastest, but always capable of getting the job done.
The downside is the setup process. It often involves some trial and error: drive onto a stack, check your level, realize you need one more, back off, add a block, and try again. They can also become brittle and crack in extreme cold or under the weight of a very heavy Class A motorhome. Despite this, their balance of cost, weight, and versatility makes them the go-to choice for a huge number of RVers.
Lynx Levelers: The Original Interlocking System
Level your RV easily and securely with the Tri-Lynx Lynx Levelers. This 10-pack supports up to 40,000 pounds and features a modular design for customized leveling on any terrain.
Lynx Levelers are the originators of the interlocking block system, and they carry a reputation for uncompromising quality. While they look similar to other brands, many seasoned RVers insist the proprietary polymer and reinforced design make them noticeably more durable. They feel solid, resist crushing, and hold up for years of constant use.
What sets Lynx apart is the complete system they’ve built around the blocks. They offer "Lynx Caps" that create a flat, secure top surface, "Stop ‘N Chock" pieces that integrate with the blocks, and even a "Lynx Lites" version for smaller rigs. This ecosystem approach means all your components work together seamlessly, creating a more stable and secure foundation than a mix-and-match setup.
Choosing Lynx often comes down to a belief in buying something once and having it last forever. They are priced as a premium product, and you’re paying for that robust engineering and brand reputation. For full-timers or those with heavy rigs who can’t afford a failure, the peace of mind offered by the original interlocking leveler is a powerful draw.
BAL Tire Leveler: Precision for Single-Axle Rigs
Effortlessly level your light trailer with this tire leveler, eliminating the need for blocks or ramps. It fits 13", 14", and most 15" wheels and includes a ratchet wrench for easy adjustment.
The BAL Tire Leveler is a unique tool designed for a specific job: leveling single-axle trailers with absolute precision. It’s not a block or a ramp, but a heavy-duty steel device that fits around the tire. You use an included ratchet wrench to raise a set of pads that lift the entire tire and wheel assembly off the ground, allowing for micro-adjustments until you are perfectly level.
This is the ultimate solution for anyone who demands perfection. You can dial in the level to the millimeter without ever moving your trailer back and forth. It also serves as a very effective wheel chock, locking the tire in place and adding significant stability. For owners of A-frames, pop-ups, or smaller travel trailers, it’s a remarkably effective piece of engineering.
The BAL Leveler’s specialization is also its main limitation. It is not designed for dual-axle trailers or motorhomes. It’s also significantly heavier and bulkier than a stack of plastic blocks. Think of it as a specialist’s tool: if you have a single-axle rig and hate the guesswork of blocks, this is hands-down the best product you can buy. For everyone else, it’s a non-starter.
Valterra Stackers: Heavy-Duty Support Solution
Valterra Stackers enter the interlocking block market with a focus on heavy-duty performance. They are engineered to support the immense weight of large Class A motorhomes and fifth wheels. Each block has a thick, ribbed structure designed to prevent crushing and provide a solid, wide base that distributes the load effectively, especially on soft surfaces like sand or gravel.
Like other block systems, they are modular and can be configured for use under tires, jacks, or stabilizers. They often come in a convenient zippered storage bag, making them easy to transport and keep organized. Users frequently praise their durability, noting they withstand the weight of 30,000+ pound rigs without showing signs of stress.
The primary reason to choose Valterra over competitors is for that heavy-duty assurance. If you own a large, heavy RV, you simply can’t risk a block failing under load. While the setup process involves the same trial-and-error as other blocks, the confidence that comes from placing your home on a foundation built for the task is invaluable.
Hopkins FloTool Ramp: Simple, Graduated Lifting
Easily access your vehicle's underside with these durable RhinoRamps MAX. Featuring a 17-degree incline for low clearance vehicles and a non-skid base for stability, they support up to 16,000 lbs. GVW.
For those who want something simpler than stacking blocks but less expensive than an Andersen, the Hopkins FloTool Ramp is an excellent middle ground. This is a single, solid piece of molded plastic with several built-in tiers, typically offering three different lift heights in one unit. You simply identify which side of the RV is low and drive onto the appropriate step.
The beauty of this design is its simplicity. There are no interlocking pieces to manage, nothing to assemble, and no parts to lose. It’s an incredibly durable, no-fuss solution that’s perfect for smaller travel trailers, truck campers, or conversion vans. It’s often one of the most affordable options available, making it a great choice for new RVers.
The tradeoff for that simplicity is a lack of precision. You are limited to the three or four pre-set heights on the ramp. If you need a 2.5-inch lift and the steps are at 1.5 and 3.5 inches, you have to choose the one that’s "close enough." For many, this is perfectly acceptable, but for those who want a perfectly level setup every time, the lack of fine-tuning can be a drawback.
Choosing Your Blocks: Weight, Lift, and Material
Ultimately, the "best" leveling system is the one that best matches your RV and your travel style. A full-time RVer in a 40-foot motorhome has very different needs than a weekend warrior in a pop-up camper. Don’t just buy what’s popular; buy what’s right for your specific situation.
To make the right choice, focus on these key factors:
- Weight Capacity: This is non-negotiable. Your levelers must be rated to support the weight of your rig. Check your RV’s Gross Vehicle Weight Rating (GVWR) and ensure your chosen blocks can handle it with a margin of safety.
- Lift Height & Precision: How off-level are the sites you typically visit? If you frequent primitive boondocking spots, you’ll need more lift height than someone who stays in paved RV parks. Decide if "close enough" is good enough, or if you need the perfect precision of a ramp or mechanical leveler.
- Setup Style: Are you a solo traveler who values speed? The Andersen might be for you. Do you prefer a versatile, multi-purpose tool and don’t mind a little trial and error? Classic blocks from Camco or Lynx are a great fit.
- Storage Space: Blocks are generally easy to store, but heavy-duty ramps or mechanical levelers like the BAL can take up significant space and add weight. Consider where you’ll keep them when you’re on the move.
Your leveling blocks are the literal foundation of your mobile home. Skimping here can lead to appliance damage, discomfort, and even safety issues. Invest in a quality system that you trust, and you’ll be rewarded with a stable, comfortable, and worry-free experience at every campsite you visit.
Finding that perfectly level, rock-solid feeling is one of the great satisfactions of setting up camp. Whether you choose the speed of a ramp, the precision of a mechanical jack, or the versatility of classic blocks, the right system makes all the difference. Choose wisely, and you’ll build your home on a solid foundation, no matter where the road takes you.
