Picture this: You’ve finally arrived at your dream campsite with a stunning view. You unhitch, set up camp, and get ready to relax—only to realize your trailer is tilted at an awkward angle. The doors won’t stay shut, your refrigerator is struggling, and every step feels like you’re on a ship in rough seas.
This is where travel trailer leveling blocks become your best friend. These simple yet essential accessories transform uneven terrain into a stable, comfortable living space. Let’s explore everything you need to know about choosing and using them.
Why Leveling Your Travel Trailer Matters
Leveling isn’t just about comfort—it’s about safety and equipment protection. Here’s why getting it right matters :
Appliance Protection: Most RV refrigerators, especially absorption-style units, must operate within specific angles (typically within 3 degrees front-to-back and 6 degrees side-to-side). If your trailer isn’t level, the refrigerant mixture separates, leading to poor cooling or permanent damage .
Safety and Comfort: An unlevel trailer creates fall hazards inside your RV. Doors and cabinet doors may swing open unexpectedly. Sleeping becomes uncomfortable when you’re constantly sliding to one side .
Structural Integrity: Proper leveling prevents stress on your trailer’s frame, slide-outs, and stabilizer jacks. Improper leveling can cause window and door frames to warp over time, leading to sealing problems .
Slide-Out Operation: Slide-outs function best when the trailer is level. Deploying them on uneven ground can bind mechanisms or damage seals .
Types of Travel Trailer Leveling Blocks
Not all leveling blocks are created equal. Understanding your options helps you choose the right solution for your setup.
Interlocking Plastic Stacking Blocks
These are the most popular choice for good reason. Typically made from durable polypropylene, these blocks feature a Lego-like design that allows precise height adjustments . Most have a uniform thickness (often 1.5 inches per block) and lock together securely .
Pros: Lightweight, easy to store, customizable height, weather-resistant, and affordable .
Cons: Some models can crack under heavy loads, especially on rough terrain. Manufacturer recommendations typically limit stacking to 4.5 inches total height for safety .
RV Leveling Ramps
Ramps offer a quick, straightforward solution. You simply drive your trailer onto the tapered ramp until it reaches the desired height .
Pros: Fast setup, works well for solo campers, and designed for gradual tire ascent .
Cons: Limited height adjustment (typically up to 4 inches), may slip on some surfaces, and less precise than stacking blocks .
Wood Blocks
Some RVers opt for DIY wood blocks, often cutting pressure-treated lumber into appropriate sizes .
Pros: Inexpensive and readily available .
Cons: Heavy, bulky, susceptible to rot and splintering, and difficult to store efficiently. Most experienced campers eventually switch to plastic alternatives .
Solid Rubber or Composite Blocks
These provide excellent grip and stability, often featuring nonslip surfaces .
Pros: Durable, good traction, and resist weather damage .
Cons: Typically more expensive and less customizable for height adjustments.
How to Level Your Travel Trailer: Step-by-Step Guide
Before You Start: Essential Tools
- Leveling blocks (interlocking or ramp-style)
- Bubble level or digital level (LevelMatePRO offers helpful wireless guidance)
- Wheel chocks
- Tongue jack
- Jack pad or solid board for soft ground
Step 1: Position Your Trailer
Park your travel trailer about 2-3 feet ahead of your final position. Choose a spot that’s as level as possible and ensure all utility hookups (electric, water, sewer) can reach their connections .
Step 2: Level Side-to-Side
This is the most critical step and must be done before unhitching from your tow vehicle .
- Check the level: Place a bubble level on your trailer floor or use a LevelMatePRO app to determine which side is lower.
- Place your blocks: Position the leveling blocks in front of the tires on the lower side. If using interlocking blocks, stack them like stepping LEGOs—creating a gentle ramp up . Start with a conservative height (1-2 layers) because you can always add more.
- Drive onto the blocks: Slowly and carefully drive your trailer forward onto the blocks until the tires rest securely on them. Have someone guide you if possible .
- Recheck your level: Step out and check your bubble level again. If you’re not level, repeat the process—back off, add or remove blocks, and try again .
Pro Tip: If you have tandem axles, you’ll need enough blocks to support both tires on the same side. Some RVers use ramp-style levelers specifically designed for tandem setups .
Step 3: Chock the Wheels
Once you’ve achieved side-to-side level, immediately chock the wheels before doing anything else. Place chocks in front of and behind the wheels on the ground to prevent any movement .
Step 4: Unhitch the Tow Vehicle
Now you can safely unhitch your trailer:
- Place a jack pad or additional leveling block under your tongue jack to prevent it from sinking into soft ground .
- Lower the tongue jack until it firmly contacts the pad.
- Unhitch the trailer from your tow vehicle.
Step 5: Level Front-to-Back
With the trailer now off the tow vehicle, use your tongue jack for final front-to-back adjustment :
- Place your bubble level perpendicular to the side-to-side direction.
- Raise or lower the tongue jack gradually while monitoring the level.
- Work slowly—small adjustments at the tongue create noticeable changes at the rear of the trailer.
Step 6: Deploy Stabilizer Jacks
After achieving proper level, deploy your stabilizer jacks to eliminate bouncing and swaying:
- Lower each stabilizer jack until it just contacts the ground with light pressure.
- Important: Stabilizer jacks are meant to stabilize, not level the trailer. Using them for leveling can damage your jacks and trailer frame .
- Start with the jack diagonal to your tongue jack, then alternate corners to maintain even weight distribution .
What to Look for When Buying Leveling Blocks
Weight Capacity
Ensure your leveling blocks can support your trailer’s weight plus a safety margin. Single-block capacities range from 2,000 lbs to over 8,800 lbs, with some well-known brands being compatible with virtually any RV .
Material Quality
Look for blocks made from high-strength polypropylene or durable nylon polymers that resist UV rays, water, oil, and temperature extremes . Some interlocking models show durability issues when used on rough terrain, so consider your typical camping conditions when choosing .
Height Adjustability
The ability to stack blocks in precise increments (typically 1-1.5 inches per layer) allows you to fine-tune your leveling. Most manufacturers recommend not exceeding 4.5 inches of total lift for safety .
Storage and Portability
Lightweight, compact designs with carrying handles or storage bags make a significant difference when you’re setting up and breaking down camp regularly .
Common Mistakes to Avoid
Using Stabilizer Jacks for Leveling
This is the most dangerous and common mistake. Stabilizer jacks are designed to reduce bounce, not to lift or level your trailer. Using them for leveling can damage both the jacks and your trailer frame .
Over-Stacking Blocks
Safety and stability decrease with each added layer. If you need more than 4-5 inches of lift, consider repositioning your trailer to a more level spot or using ramp-style levelers designed for greater height .
Forgetting to Chock the Wheels
Even with leveling blocks, unsecured trailers can roll. Always chock wheels—on both sides of each wheel remaining on the ground—before unhitching or entering your trailer .
Deploying Slide-Outs Before Leveling
Always complete the entire leveling process before extending any slide-outs. Slide-outs operate best on level surfaces and can bind or suffer seal damage when deployed on unlevel ground .
Popular Leveling Block Brands
While specific product recommendations can be helpful, remember that the best choice depends on your specific trailer’s weight, your typical camping terrain, and your budget. Brands like Anderson, Lynx, Camco, and Beech Lane are commonly mentioned, each with different strengths and features .
Final Thoughts: Leveling for Peace of Mind
Investing in quality travel trailer leveling blocks and learning proper leveling techniques transforms your camping experience. No more worrying about refrigerators failing, doors swinging open, or uncomfortable sleeping. Instead, you’ll enjoy stable, comfortable camping—whether you’re at a state park, a national forest campground, or boondocking in the backcountry.
Take time to practice your leveling routine at home, and you’ll soon be setting up camp like a pro in under 10 minutes. Happy camping!
