7 Best Heavy Duty Chocks For Steep Driveways RV Nomads Swear By

You’ve backed your rig into that perfect, secluded spot, but the ground slopes away more than you’d like. A standard yellow plastic chock feels terrifyingly inadequate against the sheer mass of your home on wheels. On a steep grade, your wheel chocks aren’t just a parking accessory; they are your most critical piece of safety equipment.

Why Steep Grades Demand Heavy-Duty RV Chocks

Gravity is a relentless force. On a steep driveway or a sloped campsite, that force is constantly trying to pull thousands of pounds of RV downhill. The small, hollow plastic chocks that come with many rigs are designed for flat, level pavement. They simply lack the mass and grip to counteract the immense, sustained pressure an incline creates.

Under this kind of load, lightweight chocks can slip on gravel, deform on hot asphalt, or even crack under the strain. The physics are simple but unforgiving. The steeper the angle, the more of your RV’s weight is converted into forward-rolling force. Heavy-duty chocks are designed with superior materials and aggressive designs to fight that specific force.

Look for chocks made of solid, high-density rubber or reinforced steel. These materials don’t just block the tire; they grip it and the ground. Solid rubber has the added benefit of conforming slightly to imperfections in the surface, creating more contact and friction. This isn’t about over-engineering; it’s about respecting the forces at play and ensuring your home stays exactly where you parked it.

BAL X-Chock: Ultimate Tandem Axle Security

For any rig with tandem axles, an X-Chock is a game-changer for stability and security. Unlike a traditional chock that sits on the ground, the BAL X-Chock fits between the tires. You use an included ratchet wrench to expand it, which applies opposing force to both tires, effectively locking the wheels in place.

This mechanism does more than just prevent rolling. It virtually eliminates the fore-and-aft shifting that makes an RV feel bouncy when you walk around inside. On a steep grade, this stabilization becomes a powerful safety feature. By locking the tires against each other, it leverages the trailer’s own suspension to create an incredibly secure hold that ground chocks alone can’t replicate.

Here’s the crucial, non-negotiable rule: X-Chocks are a supplement to, not a replacement for, standard ground chocks. Always set your ground chocks first before unhitching. Then, install the X-Chocks to add that next level of rock-solid security. Removing them is the last step you take before pulling out.

Andersen Camper Leveler: Chock and Leveler

The Andersen Camper Leveler is an ingenious solution that tackles two jobs at once. It’s a single, curved plastic ramp you drive onto to level your rig side-to-side, offering up to four inches of lift. Once you’re level, you slide a corresponding curved chock under the low side of the leveler, locking the entire system—and your tire—firmly in place.

The genius is in the design. Because the leveler is curved, the entire weight of the RV is pressing down and trying to flatten it. The chock piece prevents this, creating a system under constant compression. This makes it exceptionally secure on inclines, as the RV’s own weight is the primary force holding it steady. There is a massive amount of surface contact with the tire, which is far more secure than a small chock just touching the bottom edge.

This system is particularly loved by nomads who move frequently. It’s faster than stacking blocks and provides a very precise level. Its ability to double as a highly effective chock makes it one of the most efficient pieces of gear you can carry, saving both time and storage space.

MaxxHaul Solid Rubber Chock for Maximum Grip

Sometimes the best solution is the simplest and most robust. The MaxxHaul Solid Rubber Chock is exactly that: a hefty, durable block of high-density rubber. There are no moving parts to fail and no hollow plastic to crack. It’s pure, brute-force stopping power.

The key advantage is the material itself. Solid rubber is heavy, which helps it stay put, and it has a natural high coefficient of friction. Paired with an aggressive ribbed texture, these chocks bite into both the tire and the ground surface, whether it’s asphalt, gravel, or dirt. They provide a level of grip that lightweight plastic simply cannot match.

While their weight is a drawback for those counting every ounce, it’s also a feature. You can feel the quality and know it won’t fail. Many models include a built-in steel handle or eyelet, making it easy to position them or pull them out with a rope. For maximum peace of mind on a serious grade, the simplicity of a massive rubber block is hard to beat.

Camco Super Wheel Chock: A Trusted RV Classic

If you’ve spent any time in a campground, you’ve seen Camco products. Their Super Wheel Chock is a significant step up from the basic yellow pyramids. It’s a larger, more robustly designed chock made from durable, UV-stabilized plastic, offering a good balance of performance and weight.

This is the reliable workhorse for moderate grades and for RVers who need more security without committing to the weight of solid rubber. The ribbed design is more aggressive than on smaller chocks, and its larger footprint provides better stability. It’s a well-understood and widely trusted product in the RV community for good reason.

However, it’s important to understand its place. While it’s labeled "Super," it’s still a plastic chock. On a truly steep, slick driveway, it won’t provide the same level of absolute grip as a solid rubber or steel system. Think of it as the perfect heavy-duty option for most common situations, or as an excellent secondary chock in a multi-layered safety system.

Fastway ONEstep: The All-in-One Stabilizer

Similar in principle to the X-Chock, the Fastway ONEstep is a between-the-wheel chock for tandem axles, but with a focus on incredible ease of use. Instead of needing a ratchet, the ONEstep uses a clever scissor mechanism that you can set and tighten with your foot. You simply slide it between the tires and step on the central arm to lock it securely in place.

This convenience is a massive quality-of-life improvement. For full-timers or frequent weekenders, eliminating the need to kneel on wet or rocky ground with a wrench is a huge win. The chocks lock the tires together, creating the same motion-dampening stability as other between-the-wheel systems, making the entire rig feel more solid.

On a steep grade, that stability translates directly to safety. By immobilizing the wheels against each other, you’re adding a powerful layer of protection against rolling. Like all between-the-wheel chocks, the ONEstep must be used with ground chocks, but its combination of speed, convenience, and security makes it a top choice for nomads on the move.

ROBLOCK Heavy Duty Chock: Industrial Strength

When you need absolute, uncompromising stopping power, you look to the industrial sector. ROBLOCK and similar brands produce heavy-duty chocks that are essentially scaled-down versions of what you’d see holding a semi-truck at a loading dock. They are often made from thick, reinforced rubber or high-impact polyurethane and are significantly larger and heavier than typical RV chocks.

These chocks are designed for extreme loads and conditions. Their oversized, aggressive designs are meant to hold vehicles weighing many times more than even the largest Class A motorhome. The sheer mass and surface area provide a level of security that is unmatched by anything else designed for the consumer market.

The tradeoff is obvious: size and weight. These are not small, and they are not light. Storing a pair can be a challenge in an already-cramped RV. This is the choice for the RVer who prioritizes safety above all else, especially if they plan to park a heavy rig on a questionable slope for an extended period.

Ultra-Fab Super Grip: No-Slip Tandem Chocking

The Ultra-Fab Super Grip Chock offers another excellent take on the between-the-wheel stabilizer concept for tandem axle trailers. It provides the same fundamental benefit as its competitors—locking the tires together to prevent shifting and rolling—but often in a simpler, more streamlined package.

Functionally, it operates with a straightforward screw mechanism. You place the chock between the tires and turn the central screw, which pushes two textured pads outward against the tire treads. It’s a simple, robust, and highly effective design that provides a ton of holding power and stability.

The Super Grip often comes in at a more accessible price point than some other brands, making it a fantastic way to get into the world of tandem-axle stabilization. It delivers the core safety and comfort benefits of a between-the-wheel system without the premium price tag, making it a smart, practical choice for any nomad looking to upgrade their chocking game.

Ultimately, your chocks are the foundation of a safe and stable camp, especially when gravity is working against you. Don’t treat them as an afterthought; invest in a system that matches the weight of your rig and the challenges of the terrain. Always chock both sides of at least one wheel, and never, ever unhitch without them securely in place.
