Quick Answers to Common Questions

Can I use wood for travel trailer stabilizer blocks?

Yes, wooden blocks can be used, especially if they are sturdy and treated to resist moisture. However, pre-made plastic or rubber travel trailer stabilizer blocks generally offer better durability and weather resistance.

Do stabilizer blocks help with leveling?

While their primary role is stability, travel trailer stabilizer blocks can assist with initial rough leveling, especially on slightly uneven terrain, by reducing the extension needed from your leveling jacks.

How many travel trailer stabilizer blocks do I need?

You typically need one block or a stack of blocks for each stabilizer jack on your trailer. Most travel trailers have four jacks, so a set of four blocks is a common starting point.

Are heavy-duty stabilizer blocks necessary for small trailers?

For smaller travel trailers, standard plastic or rubber stabilizer blocks are usually sufficient. Heavy-duty options are more crucial for larger, heavier rigs that exert more pressure.

Should I use stabilizer blocks on all types of surfaces?

Absolutely! Travel trailer stabilizer blocks are beneficial on almost any surface, from concrete to grass, preventing jacks from sinking, improving grip, and always reducing overall jack extension.

What are Travel Trailer Stabilizer Blocks and Why Do You Need Them?

Imagine trying to build a tall, sturdy tower on a bouncy castle. It wouldn’t work, would it? Your travel trailer, even when parked, is somewhat similar. While its built-in leveling jacks provide support, they often extend quite far, making them susceptible to movement. This is where travel trailer stabilizer blocks step in.

Travel trailer stabilizer blocks are essentially solid, supportive platforms designed to be placed under your trailer’s leveling jacks or sometimes directly under the frame. Their primary purpose is to minimize the distance your leveling jacks need to extend, thus creating a shorter, more rigid support column. This significantly reduces the trailer’s ability to sway, rock, or bounce, especially when people are moving around inside.

The Benefits of Using Stabilizer Blocks

Using travel trailer stabilizer blocks offers a multitude of advantages that go beyond just eliminating the wobble.

• Unmatched Stability: This is the most obvious benefit. By providing a solid base for your jacks, travel trailer stabilizer blocks create a much more stable foundation for your RV. You’ll notice a drastic reduction in movement, making your trailer feel far more secure and comfortable.
• Protection for Your Jacks: When jacks extend to their maximum length, they are more vulnerable to bending or damage from strong winds, uneven ground, or excessive internal movement. Blocks reduce this extension, lessening the strain on the jack mechanisms and prolonging their lifespan.
• Prevents Sinking: On soft ground like sand, mud, or even damp grass, your leveling jacks can sink, causing your trailer to become unlevel or unstable. Travel trailer stabilizer blocks distribute the weight over a larger surface area, preventing your jacks from disappearing into the earth.
• Enhanced Comfort: A stable trailer means a better night’s sleep, a more enjoyable cooking experience, and less seasickness for those sensitive to motion. No more feeling like you’re on a boat every time someone gets up!
• Increased Safety: A stationary trailer is a safer trailer. Reduced movement means less chance of items falling, less strain on connections like water and sewer hoses, and a generally more secure environment for you and your family.
• Easier Leveling: In some cases, especially on moderately uneven terrain, travel trailer stabilizer blocks can also be used as initial leveling aids to get your trailer roughly level before fine-tuning with your jacks.

Just like there are different types of travel trailers, there are various kinds of travel trailer stabilizer blocks, each with its own characteristics and best uses. Understanding these differences will help you choose the right set for your specific needs.

Plastic/Polymer Blocks

These are perhaps the most common and widely recognized travel trailer stabilizer blocks. Made from high-density polyethylene (HDPE) or other durable plastics, they are lightweight, stackable, and often brightly colored for visibility.

• Pros: Lightweight, easy to clean, weather-resistant, often interlocking for secure stacking, good weight distribution.
• Cons: Can be prone to cracking under extreme weight or cold temperatures if not high quality, might slip on very slick surfaces unless they have a non-slip design.
• Common Use: Ideal for most casual to moderate campers, available in various sizes and weight capacities.

Rubber Blocks

Rubber travel trailer stabilizer blocks are usually heavier and offer superior grip, especially on concrete or asphalt. They are often made from recycled rubber.

• Pros: Excellent grip, very durable, resistant to cracking, absorbs some vibration, good for heavy trailers.
• Cons: Heavier than plastic, can be more expensive, might degrade over many years if exposed constantly to harsh UV rays.
• Common Use: Excellent for all types of trailers, particularly those seeking maximum grip and durability, or for heavier rigs.

Wooden Blocks

Before plastic and rubber became prevalent, wooden blocks were the standard. Many experienced RVers still swear by them. They can be custom-made from scrap lumber.

• Pros: Inexpensive (especially if DIY), strong, readily available, can be cut to custom sizes.
• Cons: Can absorb moisture leading to rot or mold, heavier, less durable than plastic/rubber in the long run if not treated, can split.
• Common Use: Budget-conscious campers, DIY enthusiasts, or as supplementary blocks for specific situations.

Specialized Stabilizer Blocks and Pads

Beyond the basic types, there are also specialized products. Some travel trailer stabilizer blocks are designed with unique interlocking patterns, or feature integrated leveling ramps. Others are simply robust pads specifically made to go under jacks. You might also find combination kits that include both leveling ramps and flat stabilizer pads.

How to Properly Use Travel Trailer Stabilizer Blocks for Maximum Stability

Having the best travel trailer stabilizer blocks won’t do you any good if you don’t use them correctly. The process is straightforward, but attention to detail makes all the difference in achieving that rock-solid feeling.

Step-by-Step Guide to Stabilizing Your Trailer

Follow these steps for optimal stability when setting up your travel trailer.

1. Park and Chock Your Wheels: Before anything else, park your travel trailer on as level a spot as possible. Once parked, immediately place sturdy wheel chocks on both sides of at least one wheel on each side of the trailer (or both wheels if you have a tandem axle) to prevent any accidental movement. This is non-negotiable for safety.
2. Rough Leveling (if needed): If your site is significantly unlevel side-to-side, use leveling ramps or additional blocks under the low-side wheels to get your trailer mostly level before deploying your jacks. Do not use your stabilizer jacks for primary leveling.
3. Identify Jack Points: Locate all your trailer’s leveling or stabilizer jacks. Most travel trailers have four – one at each corner. Some might have additional center jacks.
4. Position Your Stabilizer Blocks: Place your chosen travel trailer stabilizer blocks directly under each jack point. The goal is to minimize the extension of the jack. Stack blocks if necessary to reach the desired height, ensuring they are stable and flat on the ground. For plastic blocks, interlock them securely. For wooden blocks, ensure they are flush.
5. Extend Jacks to Meet Blocks: Slowly extend your leveling jacks until they make firm contact with the stabilizer blocks. Do not lift the trailer off its wheels with the stabilizer jacks; they are for stabilizing, not lifting the entire weight. The wheels should always remain firmly on the ground, bearing the majority of the trailer’s weight.
6. Apply Gentle Pressure: Once all jacks are in contact with their respective travel trailer stabilizer blocks, apply gentle, even pressure. You’ll feel the trailer begin to firm up. Avoid over-tightening, as this can twist the frame or damage the jacks. The idea is to take the “play” out of the suspension, not to lift the trailer.
7. Test for Stability: Once you believe the trailer is stable, walk around inside, checking for any remaining wobble. If you detect movement, slightly adjust the jacks, perhaps extending them a tiny bit more, or re-evaluating the block placement.
8. Consider X-Chocks (Optional but Recommended): For even greater stability, especially on tandem axle trailers, consider adding X-chocks between the wheels. These expand to apply pressure against the tires, further reducing movement.

Important Tips for Optimal Results

• Start with Level Ground: The flatter your starting point, the less work your travel trailer stabilizer blocks and jacks have to do.
• Solid Surface is Best: Always place your blocks on the most solid part of the ground. Avoid placing them directly on loose gravel, soft dirt, or muddy spots without a larger, rigid base plate underneath.
• Don’t Over-Extend Jacks: Remember, jacks are for stability, not for lifting the trailer off the ground. Minimize extension as much as possible.
• Use All Jacks: Utilize all available stabilizer jacks on your trailer, in conjunction with your travel trailer stabilizer blocks, for the best results.
• Regular Inspection: Periodically check your blocks and jacks during your stay, especially after heavy winds or if the ground gets wet and soft.

Choosing the Right Travel Trailer Stabilizer Blocks for Your Rig

With so many options, how do you pick the perfect set of travel trailer stabilizer blocks? Consider these factors to make an informed decision.

Weight Capacity

The most critical factor is ensuring your travel trailer stabilizer blocks can safely support the weight of your trailer. While the jacks primarily carry the weight, the blocks provide the foundation. Always check the manufacturer’s specified weight capacity for both your jacks and the blocks. For larger, heavier trailers, opt for robust, heavy-duty blocks.

Material and Durability

Think about where and how often you’ll be camping.

• Plastic: Great all-around, good for most conditions. Look for high-quality, UV-resistant plastic to prevent brittleness.
• Rubber: Excellent for grip and extreme durability, especially on hard surfaces. A good investment if you camp frequently or have a heavy rig.
• Wood: Best for occasional use or as a budget-friendly option, but requires more care to prevent rot.

Stackability and Storage

Travel trailer stabilizer blocks can take up valuable storage space.

• Interlocking Designs: Many plastic blocks interlock, making them stable when stacked high and easy to store compactly.
• Nesting Blocks: Some designs allow smaller blocks to nest inside larger ones.
• Size: Consider the overall dimensions when stacked versus the available storage compartments in your trailer.

Grip and Surface Compatibility

Where do you typically camp?

• Smooth Surfaces (asphalt, concrete): Rubber blocks offer superior grip. Plastic blocks with textured or ribbed surfaces also work well.
• Soft Surfaces (grass, dirt): Larger footprint blocks or those designed to spread weight broadly are beneficial to prevent sinking.
• Uneven Terrain: A combination of different sized travel trailer stabilizer blocks or those with an integrated ramp can be useful.

Cost

Travel trailer stabilizer blocks range from very affordable DIY wooden options to premium rubber or specialized plastic sets. While it’s tempting to go for the cheapest, consider them an investment in your comfort and safety. A good quality set will last for many years.

Maintenance and Storage Tips for Your Travel Trailer Stabilizer Blocks

Like any piece of camping gear, a little care goes a long way in ensuring your travel trailer stabilizer blocks last for many seasons.

Cleaning

After use, especially if they’ve been in mud or dirt, give your blocks a quick rinse. A simple hose-down is usually sufficient for plastic and rubber blocks. For stubborn grime, a brush and mild soap can be used. Ensure they are dry before storing to prevent mildew or unpleasant odors, particularly for wooden blocks.

Inspection

Before and after each trip, take a moment to inspect your travel trailer stabilizer blocks.

• Plastic: Check for cracks, chips, or significant deformation. A severely damaged block should be replaced.
• Rubber: Look for deep cuts, tears, or signs of dry rot (though less common).
• Wood: Check for splinters, significant cracks, or signs of rot/insect damage. Consider applying a wood sealant annually if you use wooden blocks frequently.

Proper Storage

• Cool, Dry Place: Store your blocks in a place that’s not exposed to extreme temperatures or direct sunlight for prolonged periods, especially for plastic which can become brittle.
• Organized: Many travel trailer stabilizer blocks come with storage bags or straps. Utilize these to keep them together and prevent them from rattling around in your storage compartments.
• Away from Chemicals: Avoid storing them near petroleum products, strong solvents, or acids, as these can degrade certain plastics and rubbers.

Beyond Blocks: Complementary Stability Solutions

While travel trailer stabilizer blocks are incredibly effective, they are just one part of a comprehensive stability strategy. Combining them with other accessories can create an unshakeable foundation for your RV.

Wheel Chocks

As mentioned earlier, wheel chocks are the first and most critical step in stabilizing your trailer. They prevent your wheels from rolling. There are basic wedge chocks and more advanced models that grip the tire. Always use them!

X-Chocks (for Tandem Axles)

If your travel trailer has two axles (a tandem axle), X-chocks are a game-changer. These devices fit between the two tires on the same side and expand to apply opposing pressure to both wheels. This locks the wheels, preventing them from rotating even slightly, which eliminates a significant source of trailer movement. When used in conjunction with high-quality travel trailer stabilizer blocks, X-chocks provide an unparalleled level of stability.

Scissor Jacks and Tripods

Some larger or older travel trailers might use scissor jacks as their primary stabilizers, or you might choose to add heavy-duty tripod stabilizers under the tongue of your trailer for extra front-to-back stability. Just like with regular jacks, placing travel trailer stabilizer blocks under these can enhance their effectiveness and protect them.

Frame-Mounted Stabilizers

These are often factory-installed or can be aftermarket additions. They are permanently attached to the trailer’s frame and deploy directly to the ground. Even with these, using travel trailer stabilizer blocks underneath can provide additional height and protection from soft ground.

King Pin Stabilizers (for Fifth Wheels)

While this article focuses on travel trailers, it’s worth noting that fifth-wheel owners often use king pin stabilizers, which are large tripods placed under the trailer’s king pin (the hitch point). These, too, benefit from solid footing provided by sturdy travel trailer stabilizer blocks.

In conclusion, travel trailer stabilizer blocks are far more than just optional accessories; they are fundamental to a comfortable, safe, and enjoyable RV experience. By understanding their purpose, choosing the right type, and using them correctly, you can transform your bouncy mobile home into a wonderfully stable sanctuary. No more waking up to the feeling of a mild earthquake when someone gets a glass of water! Invest in a good set of travel trailer stabilizer blocks, learn to use them well, and get ready to enjoy the calm, steady comfort of your perfectly stable home away from home. Happy camping!

Frequently Asked Questions

What’s the main difference between leveling blocks and stabilizer blocks?

Leveling blocks are primarily used under the wheels to adjust the trailer’s height and achieve a level stance from side-to-side. Travel trailer stabilizer blocks, on the other hand, are placed under the stabilizer jacks to reduce sway and movement once the trailer is level and chocked, minimizing jack extension.

How do travel trailer stabilizer blocks prevent trailer sway?

By providing a solid, elevated foundation for your trailer’s stabilizer jacks, these blocks significantly reduce how far the jacks need to extend. Shorter, more rigid support columns are far less prone to bending, flexing, or swaying, which translates to a much more stable trailer body.

Can I stack stabilizer blocks?

Yes, many travel trailer stabilizer blocks are designed to be stacked. When stacking, ensure they interlock securely or are placed on a flat, stable surface to prevent slippage. Always stack only as high as necessary to keep jack extension to a minimum.

Are travel trailer stabilizer blocks necessary if I have auto-leveling jacks?

Even with auto-leveling jacks, using travel trailer stabilizer blocks is highly recommended. They still reduce the extension of the jacks, protecting the mechanisms, preventing sinking into soft ground, and ultimately improving the overall stability that the auto-leveling system provides.

How do I know what size travel trailer stabilizer blocks to get?

The size depends on your trailer’s weight and the typical terrain you camp on. For general use, blocks with a surface area of about 8×8 inches or larger are good. Heavier trailers benefit from larger, more robust blocks, and you’ll need enough blocks to stack to the height required for your jacks.

Where should I store my travel trailer stabilizer blocks?

Store your travel trailer stabilizer blocks in a dedicated storage compartment on your RV or in a sturdy bag to keep them organized. Ensure they are clean and dry to prevent mildew and prolong their lifespan. Avoid leaving them exposed to prolonged direct sunlight when not in use.
