6 Best Chocks For Tiny House On Wheels Foundation Nomads Swear By

That subtle but unnerving wiggle you feel when walking around your tiny house isn’t just in your head. It’s a constant reminder that your home, weighing thousands of pounds, is sitting on rubber tires. Your foundation isn’t concrete; it’s a dynamic system of wheels, axles, and suspension that needs to be properly secured.

Why Your Tiny House Foundation Needs Solid Chocks

Your tiny house on wheels (THOW) is significantly heavier than the average travel trailer. A cheap, hollow plastic chock designed for a 3,000-pound camper is a liability when tasked with holding a 14,000-pound home. The forces at play are entirely different, and failure isn’t just an inconvenience—it’s a serious safety risk.

Solid chocks are the first and most critical component of a stable foundation. They do more than just prevent your house from rolling away on a slope. They are the primary defense against the subtle, constant movement that can stress your plumbing connections, throw your level off, and create that "living on a boat" feeling every time someone moves.

Think of it this way: every step you take, every gust of wind, every time the washing machine hits its spin cycle, that energy transfers into the suspension. Without robust chocks locking the wheels in place, your entire home shifts and sways. Good chocks transform your tiny house from a vehicle into a stable dwelling.

BAL X-Chock: Ultimate Tandem Axle Stabilization

For tiny houses with tandem or triple axles, the BAL X-Chock is legendary for a reason. Instead of just wedging against the front or back of a tire, this device expands between two tires, applying opposing force to both. This locks the tires against each other and effectively freezes that entire side of your suspension.

The result is a dramatic reduction in the front-to-back rocking motion that standard chocks can’t prevent. If you’ve ever felt the whole house lurch when someone walks from the loft to the kitchen, an X-Chock is your solution. They provide a level of stability that makes your house feel significantly more grounded and solid.

The main consideration is fit. X-Chocks are designed for specific axle spacings, so you must measure the gap between your tires before buying. They also take a minute to install with the included ratchet wrench, so they’re best for people who plan to stay parked for more than a few days at a time. For long-term parking, they are an absolute game-changer.

Camco Super Wheel Chock: Simple, Heavy-Duty Grip

Sometimes, the simplest solution is the best one. The Camco Super Wheel Chock is a no-frills, heavy-duty wedge that gets the job done without any complexity. Made from a durable, UV-stabilized polymer, it’s designed to be bigger and more robust than standard RV chocks, making it a suitable choice for the weight of a tiny home.

This chock’s strength lies in its straightforward design and aggressive grip. The ribbed construction provides traction on various surfaces, from asphalt to packed gravel. It’s a classic "wedge it and forget it" tool that provides reliable protection against rolling. You simply can’t install it wrong.

However, a wedge-style chock only prevents rolling. It won’t do much to stop the subtle jiggle and sway that comes from the suspension. For this reason, many nomads use these in conjunction with X-Chocks—the Camco chocks provide the primary safety against rolling, while the X-Chocks add the stabilization for better livability.

Andersen Camper Leveler: Leveling and Chocking

The Andersen Camper Leveler is a brilliant two-in-one tool for nomads who value efficiency. It’s a curved ramp that allows you to level your tiny house with incredible precision—up to four inches—simply by driving onto it. Once you’re level, a second curved wedge tucks under the leveler, effectively chocking the wheel in place.

This system eliminates the need for carrying stacks of leveling blocks and separate chocks, saving a significant amount of storage space. The process is fast and intuitive: drive on, check your level, and pop in the chock. It’s especially useful for those who move frequently and need to set up on uneven ground quickly.

The key tradeoff is that the Andersen leveler only chocks the wheel it is leveling. You will still need a traditional chock for the wheel on the opposite side to ensure your home is secured from rolling in both directions. But for combining two essential tasks into one simple motion, it’s one of the most popular and effective solutions out there.

MaxxHaul Solid Rubber Chock for Max Security

When you want absolute, unquestionable holding power, you turn to solid rubber. The MaxxHaul Solid Rubber Wheel Chock is essentially a smaller version of what you see holding semi-trucks and aircraft in place. It’s heavy, dense, and built for one purpose: to stop a wheel from moving, period.

The high-density rubber provides an incredible amount of friction, gripping pavement, concrete, and even dirt far better than plastic. Its sheer weight helps it stay put, resisting the tendency to slip out from under the tire under load. For anyone parking on a noticeable grade or who simply wants maximum peace of mind, these are the gold standard for pure stopping power.

Their weight is also their main drawback. They are heavier and bulkier to store than their plastic counterparts. They also don’t offer any of the sway-reducing benefits of an X-Chock. But for raw, brute-force security, nothing beats a big block of solid rubber.

Fastway ONEstep: Quick Between-Tire Locking

The Fastway ONEstep is a direct competitor to the BAL X-Chock, designed to solve the same problem of between-tire stabilization but with a focus on speed. Instead of using a ratchet to slowly expand the device, the ONEstep uses a lever-based system. You place it between the tires and simply step on the lever to lock it into place.

This design makes setup and removal significantly faster, which is a huge advantage for tiny house owners who move every few weeks. You get nearly all the stabilization benefits of an X-Chock with a fraction of the setup time. It’s an elegant solution for the frequent traveler.

The primary consideration is ensuring you get the right size for your axle spacing, as the ONEstep has a more limited adjustment range than the screw-style X-Chock. While it provides excellent stability, some users feel the screw-driven X-Chock allows for a slightly tighter, more customized fit. It’s a classic tradeoff: perfect fit versus ultimate speed.

ROK BLOCK Chock: Innovative Curved Design Grip

The ROK BLOCK is a clever re-imagining of the traditional wedge chock. Instead of a flat, angled surface, it features a curved face that is designed to contour to the shape of your tire. This design significantly increases the surface area contact between the chock and the tire.

More contact means better grip and a lower likelihood of the chock slipping, especially on uneven or loose surfaces where a traditional wedge might struggle to find purchase. The curved design "hugs" the tire, distributing the force more evenly. This makes it an excellent choice for parking on grass, dirt, or gravel.

Like other wedge-style chocks, the ROK BLOCK primarily prevents rolling and doesn’t address side-to-side or front-to-back sway. However, for its intended purpose, its innovative design provides an extra layer of security that many tiny dwellers appreciate, especially when parking in less-than-ideal spots.

Choosing Chocks: Axle Spacing & Weight Rating

There is no single "best" chock; there is only the best chock for your specific setup and lifestyle. Trying to use a system that doesn’t fit your home or your travel habits will only lead to frustration and potential safety issues.

Start by evaluating these key factors:

• Total Weight: Your tiny house’s GVWR (Gross Vehicle Weight Rating) is non-negotiable. Ensure any chock you buy is rated to handle that weight. Don’t guess.
• Axle Spacing: If you’re considering an X-Chock or ONEstep style stabilizer, measure the distance between your tires when the house is parked and level. This measurement will determine which model you need.
• Tire Size: While most chocks fit standard tire sizes, ensure the height and curve of your chosen chock are appropriate for your specific tires.
• Travel Frequency: If you move weekly, the speed of the Andersen or Fastway ONEstep systems is a massive quality-of-life improvement. If you’re stationary for months, the rock-solid stability of a manually-tightened BAL X-Chock combined with rubber wedges is worth the extra setup time.

Ultimately, most seasoned nomads use a combination system. They might use Andersen levelers on one side, a solid rubber chock on the other, and add X-Chocks on both sides for long-term stability. Your foundation is too important to cut corners—invest in a system that gives you both safety and comfort.

Your chocks are more than just safety equipment; they are the crucial link that turns your house on wheels into a stable, comfortable home. By choosing the right system for your rig and travel style, you can eliminate the wiggle, reduce stress on your structure, and park with confidence wherever your journey takes you.
