6 Best Chocks For National Park RV Site Leveling That Nomads Swear By
Leveling your RV in a national park? We reveal the 6 best chocks that seasoned nomads swear by for maximum stability and safety on uneven ground.
You finally pull into that perfect, secluded campsite in a National Park after a long day of driving. The view is incredible, but the parking pad slopes more than a ski hill. This is the reality of camping in the wild—pristine nature rarely comes with a perfectly paved, level spot. Getting your rig level isn’t just a luxury; it’s a fundamental requirement for comfort and for keeping your RV’s systems running correctly.

Why Leveling is Crucial in National Park Sites
Being unlevel is more than just a minor annoyance. It’s the reason your coffee cup slides off the counter, the bathroom door swings shut on its own, and you feel like you’re constantly sleeping on a hill. These daily frustrations can quickly turn a dream trip into a chore.
More importantly, your RV’s core systems depend on being level. The single most critical component is an absorption refrigerator, common in most travel trailers and motorhomes. These fridges use a gravity-fed ammonia system to create cold, and operating them more than a few degrees off-level can cause the cooling unit to overheat and fail permanently. That’s a multi-thousand-dollar repair caused by a simple mistake.
Beyond the fridge, being unlevel puts undue stress on your entire rig. Slide-outs can bind and strain their motors if the frame is twisted. Water tanks won’t read accurately, and your grey and black tanks may not drain completely, leaving you with unpleasant surprises down the road. Leveling isn’t just about comfort; it’s about protecting your investment.
Andersen Levelers for Precision on Uneven Ground
Level your camper or fifth wheel quickly and precisely with the Andersen Camper Leveler. This easy-to-use system levels at any increment from 1/2" to 4" and works on trailers up to 30,000 lbs with tires up to 32" diameter.
When you need to be perfectly level, nothing beats the precision of a curved ramp. The Andersen Leveler is the original and most well-known in this category. It’s a simple, brilliant design: a crescent-shaped plastic ramp you drive onto.
The magic is in its infinite adjustability. Unlike blocks that lift you in one-inch increments, you just drive up the ramp until your level reads perfectly, then slide the included chock under the high side of the ramp. It provides a lift from half an inch up to four inches, hitting every possible measurement in between. This eliminates the frustrating guesswork of adding or removing one more block.
The main tradeoff is storage space. These are bulky, oddly shaped pieces that don’t stack neatly like blocks. They also might be too long to fit between the tires on some dual-axle trailers, so measure your rig before buying. While they cost more than basic blocks, nomads swear by them for their speed and dead-on accuracy, especially on seriously uneven ground.
Camco Tri-Leveler: Simple, Fast, and Reliable
Level your RV up to 3-7/8 inches with the durable Camco Tri-Leveler. Its lightweight, non-slip design and built-in handle make leveling easy, supporting up to 3,500 lbs.
Sometimes, "good enough" is all you need, and you need it fast. The Camco Tri-Leveler is a classic for a reason: it’s a single, rugged piece of plastic with three built-in height levels. There are no parts to assemble, stack, or lose in the gravel.
This is the ultimate tool for a quick overnight stop. You just eyeball the slope, place the Tri-Leveler in front of the low-side tire, and drive onto the step that gets you closest to level. It’s durable, straightforward, and gets the job done with zero fuss.
Of course, its biggest strength is also its weakness. With only three fixed heights, you can’t dial in perfect levelness. You’re choosing between 1.3, 2.6, or 3.9 inches of lift (on their popular model), and nothing in between. It’s also a single, large unit, which can be awkward to store. But for simplicity and speed, it’s a reliable workhorse.
Lynx Levelers: The Ultimate Modular Block 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.
Think of Lynx Levelers as the LEGOs of the RV world. These bright orange, interlocking blocks are the go-to solution for anyone who values modularity and multi-purpose gear. You stack them into a pyramid shape to build a custom ramp for your tires.
Their versatility is their superpower. You can use them for leveling, of course, but they also serve as excellent jack pads to keep your stabilizer or tongue jack from sinking into soft ground. Because they are individual blocks, you can configure them in countless ways. They store in a compact zippered bag, taking up far less dedicated space than ramp-style levelers.
The downside is the setup process. It can be a bit of a dance: get out, check the level, realize you need one more block, get back in, and try again. Doing this in the rain is nobody’s idea of a good time. It requires more effort than a simple drive-on ramp, but their small storage footprint and multi-use flexibility make them a nomad favorite.
BAL X-Chock: Essential for Dual-Axle Stability
Stabilize your RV or trailer with this American-made X-Chock pair. Its durable, rust-resistant steel construction adjusts from 1-3/8" to 10" to reduce tire sway and improve balance. Includes a ratchet wrench for quick, secure setup.
Let’s clear up a common point of confusion: the BAL X-Chock is not a leveling device. It is a stabilizing device you use after you are leveled, and it is an absolute game-changer for any dual- or triple-axle trailer.
After you’ve leveled your rig side-to-side with blocks or ramps and unhitched, you place the X-Chock between the tires and use the included ratchet to expand it. This locks the tires together, working against the suspension and completely eliminating the fore-and-aft rocking motion that makes a trailer feel like a boat. The difference is immediate and profound.
Think of it as the final step in setting up a rock-solid camp. Your leveling blocks handle the side-to-side tilt, your tongue jack handles the front-to-back, and your stabilizer jacks handle the corners. The X-Chock ties it all together by stopping tire movement. Always place standard wheel chocks before installing or removing the X-Chocks for safety.
Level your RV on uneven terrain with these durable, interlocking blocks. The set includes 12 heavy-duty blocks (10 standard, 2 top) and a convenient carrying bag for easy storage.
Beech Lane Leveler: A Top Andersen Alternative
Level your RV precisely with this USA-made wireless system. The user-friendly phone app provides real-time leveling measurements, guiding you to perfect balance with its intuitive display.
If the concept of the Andersen curved leveler appeals to you, but you want to explore other options, the Beech Lane Leveler is your top contender. It operates on the exact same principle: a drive-on ramp that offers precise, incremental leveling for a perfect setup every time.
Beech Lane often comes in at a more competitive price point and includes some thoughtful features, like rubber grip mats that go under the levelers. These mats are surprisingly effective at preventing the ramps from sliding forward on slick surfaces like wet asphalt or loose gravel—a common frustration with the original design.
Ultimately, choosing between Beech Lane and Andersen comes down to brand loyalty, current pricing, and whether you value small feature enhancements like the grip mats. Both are exceptionally well-made and deliver on the promise of fast, frustration-free, and perfectly precise leveling. For many, the Beech Lane offers comparable performance for less money, making it a smart buy.
Hopkins FloTool Kit: All-In-One Leveling Value
For the RVer on a budget or someone just dipping their toes into the lifestyle, a comprehensive kit is a fantastic starting point. The Hopkins FloTool "Leveling Kit" is a perfect example of this. It’s a block-based system, similar in concept to Lynx Levelers, but packaged for maximum value.
These kits typically include a set of ten interlocking blocks and a wheel chock, often with a carrying handle or bag. This gives you everything you need to tackle moderately unlevel sites right out of the box. You get the same modular benefits of a block system without having to buy all the components separately.
The primary tradeoff is often in the material quality. The plastic may not feel as robust or durable as the premium-priced Lynx blocks, and they might be more prone to cracking under the weight of a heavy rig over time. However, for smaller trailers, pop-up campers, or weekend use, they represent an unbeatable value and a great, low-risk way to get your leveling system started.
Choosing the Right Leveling System for Your Rig
The best leveling system isn’t about which one is "best," but which one is right for you. The decision boils down to a core tradeoff: precision and convenience versus modularity and storage space. Understanding your priorities will point you to the perfect solution.
Here’s a simple framework to guide your choice:
- For Maximum Precision & Speed: If you have a larger rig, value a perfectly level setup, and hate guesswork, a curved ramp like the Andersen or Beech Lane is your answer. The higher cost and bulky storage are worth the convenience.
- For Ultimate Flexibility & Compact Storage: If you’re in a smaller rig where every inch of storage counts, or if you want gear that can do multiple jobs, the Lynx Levelers are unmatched. They require more effort but pay you back in versatility.
- For Simplicity or a Tight Budget: If you just want a no-fuss, fast solution for moderate slopes, the Camco Tri-Leveler is a workhorse. If you’re just starting out and want an all-in-one package, a Hopkins kit provides incredible value.
And remember, if you have a dual-axle trailer, a set of BAL X-Chocks is a non-negotiable upgrade for stability, regardless of which leveling system you choose. Don’t overthink it—pick the system that best matches your rig, budget, and the patience you have at the end of a long travel day.
A reliable leveling system is one of the best investments you can make in your RV. It transforms a challenging, sloped piece of nature into a stable and comfortable home base. By choosing the right gear, you spend less time fussing with setup and more time enjoying the incredible views from that perfect national park campsite.
