One of the first tasks you face after arriving at the campground with your camper is leveling it. Leveling an RV is not only important to ensure you can walk around in it normally, it also is important for the proper functioning of many of the appliances in an RV, including the refrigerator and range. While some campsites are on level terrain, the fact is that most are not, which means you need to level the RV yourself. 

Without the proper equipment to do so, leveling a camper, which should be fairly simple, can become a frustrating effort, setting a negative tone for what should be a relaxing retreat into nature. 

To level an RV you need a good set of leveling blocks. These blocks are made of high-grade plastic capable of holding the thousands of pounds a travel trailer or motorhome weighs. These blocks are designed to allow you to roll the RV onto them, raising one side of the trailer to bring it level. 

While all types of blocks perform the same basic function, they come in a surprisingly broad range of shapes and sizes, which can make selecting the right set for your RV confusing. We’ll help make sense of these critical RV accessories by discussing what features are crucial to consider when shopping for a set of leveling blocks. 

How We Picked These Products

Methodology

As an owner of a 30-foot travel trailer, I’ve spent quite a bit of time working with leveling blocks. It’s truly a rare campsite that is perfectly level. I used my personal experience leveling my RV coupled with the criteria below to create my list of the top leveling blocks.

  • Design: Since leveling a trailer usually follows a long day of road travel, I’ve found that it’s best to go with blocks that make leveling easy. With that in mind, I chose blocks that would allow the user to level the trailer efficiently.
  • Height: Leveling blocks must be able to raise the trailer at least a few inches to level it. With that in mind, I only chose leveling blocks that could raise a trailer at least 4 inches.
  • Construction: RVs weigh thousands of pounds and must endure resting on surfaces ranging from dirt to gravel. I only chose leveling blocks that are durable enough to repeatedly handle all of that weight and abuse without cracking.
  • Value: Although I leaned towards quality over price, leveling blocks can get surprisingly expensive. I looked for models that are reasonably priced for what they offer.

The Best Leveling Blocks: Reviews and Recommendations

Best Overall: Andersen Camper Levelers

Convenient and Versatile

These leveling blocks allow the user to make height adjustments on the fly. Andersen Hitches

Check Price

Why It Made The Cut: We love that this leveling kit allows the user to adjust the height of the RV without leaving the driver’s seat. 

Specs:

  • Weight Capacity: 30,000 pounds
  • Max height: 4 inches
  • Max tire size: 32 inches

Pros: 

  • Design allows for on-the-fly adjustments
  • Blocks stabilize as well as raise wheels
  • High weight capacity suits most RVs

Cons: 

  • Only works with RVs with wheels up to 32 inches
  • Max height of only 4 inches 

The beauty of this leveling kit from Anderson is that it allows you to adjust height without having to leave the driver’s seat. That’s because it uses a curved ramp shape as opposed to stackable blocks. The further the RV’s wheels roll over them, the higher they get. This takes the guesswork out of leveling the RV. The wheels are a bit too high? Pull forward a few inches. They’re a bit too low? Inch backward. 

Another nice feature is that these levelers also function as a stabilizer. Once the right height is found, simply slide the included chocks under the opposite side of the tires to lock the wheels in place. The levelers plus the chocks cradle the wheels, preventing the RV from shifting forward or backward. 

While this design makes leveling the wheels a much more efficient process, this set won’t work with all RVs. Their curved shape is only compatible with wheels up to 32 inches in diameter, and they aren’t wide enough to work with dual-wheeled motor homes. 

Best Value: Tri-Lynx Lynx Levelers

Effective and Affordable

This set of 10 leveling blocks offer 4 inches of leveling ability and a 40,000-pound max weight at an affordable price. Tri-Lynx

Check Price

Why It Made The Cut: This leveling kit boasts a high weight capacity while still managing to cost just a fraction of high-end leveling kits.

Specs:

  • Weight capacity: 40,000 pounds
  • Max height: 4 inches
  • Max tire size: N/A

Pros: 

  • More affordable than other leveling kits
  • High weight capacity suits most RVs
  • Easy to use

Cons: 

  • No on-the-fly leveling
  • Not quite as durable as other leveling kits

Leveling blocks can be an expensive RV accessory with some kits costing well over $100. These blocks by Tri-Lynx are a well-made affordable option. The pack consists of 10 stackable interlocking leveling blocks each of which raises an RV by 1 inch. To use, simply stack the blocks to the desired height in a pyramid shape, then back the RV over them. 

When you create a pyramid about three layers high, these levels will raise a single wheel about 4 inches. While you’ll need to purchase two packs to reach that maximum height for two-axle RVs, the total cost is still well under that of a premium leveling kit. And, despite its low price, this kit has one of the higher weight capacities at 40,000 pounds. 

That said, like other stackable leveling blocks, there’s no on-the-fly leveling here. You must use a trial and error method of adding and removing blocks to attain the right height, which can be time-consuming. 

Best for Small RVs: Camco Yellow Drive On Tri-Levelers

Easy to Use

An affordable price and on-the-fly height adjustment make these leveling blocks ideal for smaller RVs. Camco

Check Price

Why It Made The Cut: The low price and easy-to-use design of this leveling block make it a great choice for small RVs. 

Specs:

  • Weight capacity: 3,500 pounds
  • Max height: 3-7/8 inches
  • Max tire size: N/A

Pros:

  • Design allows for on-the-fly adjustments
  • Single-piece design makes it easy to store and use
  • Affordably priced

Cons: 

  • Low max weight of 3,500 pounds
  • Long length makes it suitable for single axle trailers only

This simple-to-use block from Camco is a great option for quickly leveling smaller RVs. One of the things we love about it is a one-piece design that makes it easy to level the trailer simply. Similar to ramp-style levelers, this block allows you to make adjustments from the driver’s seat by simply pulling forward or backing up. There’s no need to add and remove blocks. 

And, since it’s a single piece, you don’t need to spend time fitting multiple pieces into a bag. Simply throw this block in one of the RV’s storage bins or the back of a truck when it’s time to break camp. 

This leveling block is also one of the least expensive levelers on the market, making it a great pick for RVers on a budget. Just keep in mind that it’s only suitable for smaller RVs due to its weight max of 3,500 pounds. And, at nearly 2 feet long, it will only work with single-axle RVs. With its sloped design, you’ll also need to make sure the opposite wheel is properly chocked to prevent the RV from rolling down the leveler once it’s unhitched from the tow vehicle.

Best for Dual Axles: Camco FasTen RV Leveling Blocks

For Wide Tires

With their 17-inch width, these blocks will work with dual-tire RVs. Camco

Check Price

Why It Made The Cut: Unlike many narrower leveling blocks, these broad leveling blocks will work with the dual tires found on many RVs.  

Specs:

  • Weight Capacity: N/A
  • Max height: 4 inches
  • Max tire size: Works with dual tires

Pros: 

  • Works with dual tires 
  • Storage system makes blocks easy to store and carry
  • Easy to use

Cons: 

  • Length makes them unsuitable for dual-axle RVs

It can be difficult finding leveling blocks for RVs with wider tires or dual tires. At 4 feet wide, this set of block-style levelers from Camco provide a sturdy base for wider tires. Similar to other block levelers, they stack in a pyramid shape to add up to 4 inches of height under the wheels. 

A set with 10 pieces could easily become a mess to store. Camco uses a handle with a pole that slides through the center hole of each block and screws into a base, holding all 10 pieces neatly and securely together for easy transport and tidy storage. 

To use this kit, stack the blocks to the desired height, then drive the RV on top of the blocks. Like all block-style levelers, it does require some guesswork and adding and removing layers to reach the desired height. The total length required to use the blocks also makes them unsuitable for dual-axle trailers. 

Best for Traction: Carmtek Camper Leveler Kit

Prevent Slippage

The thick rubberized coating and anti-slip joint system ensure these leveling blocks will stay put. CARMTEK

Check Price

Why It Made The Cut: With its heavy tread and chocks that interlock with the leveling blocks, this kit is one of the best anti-slip sets of leveling blocks we could find.  

Specs:

  • Weight Capacity: 35,000 pounds
  • Max height: 4 inches
  • Max tire size: 32 inches

Pros: 

  • Rubber treads prevent slipping
  • Curved shape allows for on-the-fly leveling
  • Included chocks stabilize the wheels

Cons: 

  • More expensive than other block types

One of the biggest problems campers can run into when leveling an RV is blocks that slip out from under the wheels as it’s being moved into place. Carmtek addresses this issue with its set of levelers by covering them in thick rubber that grips both tires and the ground to prevent slippage. 

These levels work similarly to other curved levels on the market, allowing the user to adjust the height of the trailer while backing it into position, eliminating the need to add or remove blocks. And, once the proper height is reached, it includes a set of chocks that serve as stabilizers, locking the wheels into position. Carmtek uses what it calls a split joint system with small cleats on the chocks that fit into treads on the blocks, preventing them from slipping out. 

This kit also offers some of the best range on the market in terms of height and weight capacity. They can hold up to 35,000 pounds and elevate a trailer up to 4 inches. 

Things to Consider Before Buying Leveling Blocks

Weight

First and foremost, a set of leveling blocks needs to work with the specific trailer. Make sure the leveling blocks are rated to handle the weight of your RV. Leveling blocks only rated for 3,500 pounds will crumble under the weight of a 7,500-pound trailer. When considering weight capacity, consider how much the trailer weighs when loaded with people, food, supplies, and full tanks.

Compatibility

Not all blocks will work with all RV types. Consider the set-up of your rig’s wheels. Does it have dual axles with two wheels side by side? Some leveling blocks are too long to suit some double-axle trailers because the wheels are too close together. How big are the wheels? Most ramp-style levelers will only work with wheels up to 32 inches in diameter. Does your RV have dual wheels? If so, you’ll need wider blocks. Whatever the style of wheels your trailer has, make sure to choose blocks that are compatible.

Ease of Use

There is plenty of setup to do once you arrive at the campsite. Leveling the camper shouldn’t take a lot of time. If it’s in the budget and is compatible with your RV, consider going with ramp-style levelers that allow you to level your RV more efficiently than pyramid-style leveling blocks that require more time and effort.  

FAQs

Q: What is the best way to level an RV?

Follow the manufacturer’s instructions and set up the leveling blocks behind the wheel or wheels that are on the low side. Back the RV onto the blocks. Rest a carpenter’s spirit level on the back bumper of the RV to determine if it’s level. If not, make adjustments to the blocks to either raise or lower the height until it is level. 

Q: How high can you stack RV leveling blocks?

The maximum height most leveling blocks will raise an RV is about 4 inches.

Q: Do I need leveling blocks?

While there are some campsites that are level, the fact of the matter is most are not. In fact, many campsites are intentionally sloped to allow water to drain off of them more easily. And while you may be able to tolerate walking around inside an RV that sits on a slope, it’s bad for the RV. It’s unsafe to operate the refrigerator when the RV is not leveled and can be bad for other equipment, such as the slide-out.

Final Thoughts

Selecting a set of leveling blocks is really based on two main factors, what will work with your RV and what you’re willing to pay. While curved leveling blocks that make leveling easier by enabling you to make adjustments to the RV height on the fly are perhaps the best option for most RVs, the high-grade plastic required to create this style of leveling block makes them an expensive option, costing two or three times that of traditional leveling blocks. A traditional leveling block may be a more affordable way to go but keep in mind they do take longer to set up and may not work with dual-axle RVs due to their overall length.
