I'll never forget the night I learned just how important proper RV leveling is. It was my second year as an RV owner, camping in the mountains of Colorado. I'd been a bit casual about leveling—eyeballing it rather than using proper tools.
Around 2 AM, I woke to a strange gurgling sound followed by the unmistakable smell of propane. My refrigerator had shut down because the RV was too far out of level, causing the cooling system to malfunction and release that telltale odor.
Standing outside in the chilly mountain air, manually resetting the refrigerator and adjusting my leveling at that hour wasn't exactly the camping experience I'd envisioned. But that night taught me a lesson I've never forgotten: proper leveling isn't just about comfort—it's about safety, functionality, and protecting your investment.
Over my two decades of RV experience, I've seen countless examples of problems caused by improper leveling, from minor annoyances like doors that won't stay open (or closed) to major issues like damaged slide mechanisms and refrigerator failures. I've also helped dozens of fellow RVers solve leveling challenges at campgrounds across the country.
In this guide, I'll share everything I've learned about why leveling matters and how to do it right. Whether you're a weekend warrior or a full-time RVer, these insights and product recommendations will help you achieve perfect leveling every time—and avoid that middle-of-the-night refrigerator reset I experienced!
Before diving into the how-to, let's talk about why leveling your RV properly is so important.
These aren't theoretical concerns—they're real issues I've either experienced personally or helped other RVers address.
Most RV refrigerators use absorption cooling technology, which relies on gravity to circulate the cooling solution. When your RV isn't level, this circulation is compromised.
I learned this lesson the expensive way when my three-day-old refrigerator stopped cooling during a summer trip to Lake Havasu. The temperature inside reached 78°F, spoiling about $200 worth of groceries.
The culprit?
My RV was sloping 3 degrees to the left—just enough to disrupt the refrigerator's operation but not enough to be obvious without measuring tools.
Modern RV refrigerators can typically handle being off-level by 3 degrees for short periods, but manufacturers recommend staying within 1-2 degrees for optimal performance and longevity.
Consistent operation while significantly off-level can permanently damage your refrigerator's cooling unit—a repair that can cost upwards of $1,000.
Have you ever tried sleeping on a bed that's not level? It's surprisingly disruptive. You'll find yourself constantly rolling to one side, waking up with a stiff neck, or sliding off your pillow.
During a family trip to the Grand Canyon, my wife and I spent three nights sleeping with our heads noticeably lower than our feet because I hadn't properly leveled our RV.
By the third morning, we both had headaches and sore necks that put a damper on our hiking plans. A simple fix with proper leveling equipment would have prevented this discomfort entirely.
Beyond sleeping, an unlevel RV makes everyday activities frustrating. Cooking becomes an adventure as eggs roll to one side of the pan—shower water pools in the corner instead of draining properly. Cabinet doors swing open or closed on their own. These small annoyances quickly compound to create a less enjoyable camping experience.
Your RV wasn't designed to be consistently off-level, especially when slides are extended. Improper leveling puts stress on the frame, walls, and slide mechanisms.
I once helped a fellow camper who couldn't retract his slide-out at the end of a weekend trip. After some investigation, we discovered that his unlevel setup had caused the slide to twist slightly in its track.
The repair cost him over $2,000 and delayed his departure by three days while waiting for a mobile technician.
Over time, this stress can lead to:
These aren't just theoretical concerns—they're expensive repairs I've seen firsthand at RV service centers across the country.
All the plumbing systems in your RV are designed with gravity in mind. When your RV isn't level, water may not drain properly from sinks, showers, and toilets.
During a rainy week in the Pacific Northwest, I noticed water backing up in our shower pan despite the clear drain.
The culprit was our slightly off-level position, which prevented proper drainage. This created ideal conditions for mold and mildew to develop—a problem I didn't discover until weeks later when a musty smell led me to investigate.
Proper leveling ensures that:
While the refrigerator is the most sensitive appliance to leveling issues, other systems can also be affected.
My air conditioner developed a noisy vibration that I initially attributed to age or wear. After properly leveling my RV, the noise disappeared completely. The unit had been working harder than necessary because it wasn't sitting level, which could have shortened its lifespan significantly.
Other appliances affected by leveling include:
Now that we understand why leveling matters, let's talk about the equipment that makes it possible. Over the years, I've tried numerous leveling solutions, from DIY approaches to high-end automated systems.
Here are my recommendations based on real-world experience.
These stackable, interlocking blocks are the workhorses of RV leveling. I've used the same set of Ultra Leveling Blocks for over five years, and they're still going strong despite being subjected to all kinds of weather conditions and weight loads.
Why They're Essential:
I once watched in horror as a neighboring RVer tried to level his motorhome using stacked pieces of lumber.
Halfway up the makeshift ramp, the wood shifted, causing the RV to slide sideways. The potential for damage (or worse, injury) was significant. Quality leveling blocks eliminate this risk with their stable, interlocking design.
Pro tip: I keep a small hammer in my leveling kit to help separate the blocks when they're stuck together after being under pressure. This simple addition has saved me countless minutes of frustration.
For travel trailers and smaller RVs with single axles, the LIGHT TRAILER TIRE LEVELER offers a simple yet effective solution. I recommend these to new RVers because they're incredibly intuitive to use.
What Makes Them Special:
A friend with a small teardrop trailer swears by these levelers. He can set up his entire campsite in under 10 minutes, with perfect leveling every time. For single-axle trailers, these are hard to beat for simplicity and effectiveness.
While wheel levelers address the initial leveling, scissor jacks provide additional stability once you're in position. The Eaz-Lift 48810 Leveling Scissor Jack has proven itself as a reliable option that balances quality and value.
Why I Recommend Them:
I learned the importance of stabilizing jacks during a windy night in New Mexico. Despite being properly leveled with blocks, our RV swayed noticeably with each gust. After installing scissor jacks, the difference was remarkable—rock-solid stability even in high winds.
Pro tip: Apply a silicone lubricant to the screw mechanism at the beginning of each camping season. This simple maintenance step keeps the jacks operating smoothly and extends their life significantly.
You can't achieve proper leveling without accurate measurement. The Graduated RV Levels provide clear, easy-to-read indicators that take the guesswork out of leveling.
What Sets Them Apart:
Before installing these levels, I used a standard bubble level placed on the floor inside my RV.
The problem?
Floor flexion and manufacturing variations meant I wasn't getting accurate readings. Dedicated RV levels mounted to the exterior provide consistent, reliable measurements regardless of internal factors.
I place one level on the front of my RV and one on the side, allowing me to check both front-to-back and side-to-side leveling from outside the vehicle. This positioning lets me make adjustments without constantly entering and exiting the RV to check my progress.
For those seeking the pinnacle of convenience, the Bigfoot Automatic Leveling System for Mercedes Class C RVs represents the gold standard.
While it's a significant investment, the time saved and precision gained make it worth considering for frequent travelers.
Why It's Worth the Investment:
I upgraded to an automatic leveling system after calculating that I was spending approximately 20 minutes per campsite on manual leveling.
For someone who moves frequently, that time adds up quickly. Over a typical 30-night camping season, that's 10 hours spent just on leveling—time I'd rather spend enjoying my surroundings.
The system has paid for itself in convenience alone, but I've also noticed that the precision of automatic leveling has eliminated the occasional refrigerator issues I used to experience with manual methods.
Even with the right equipment, proper technique is crucial for effective leveling. Here's my tried-and-true process, refined over hundreds of setups:
Pro tip: For motorhomes, turn off the engine but leave the transmission in neutral while checking your level. This prevents transmission fluid from pooling at one end while you're taking measurements.
A word of caution: I once made the mistake of using stabilizing jacks to level my RV rather than just for stabilization. This put excessive stress on the jacks and the RV frame, resulting in a bent jack and a costly lesson. Always level with blocks or built-in leveling systems before deploying stabilizing jacks.
Even with the right equipment and technique, you'll occasionally encounter challenging leveling situations.
Here are solutions to common problems I've faced:
Some campsites, particularly in state parks and rustic campgrounds, can have significant slopes or depressions.
Solution: Layer your Ultra Leveling Blocks to create a stable ramp. I once needed to stack blocks four high to achieve proper leveling at a mountain campsite. The interlocking design kept them stable despite the significant height.
For extreme cases, consider carrying a small shovel to level out minor ground irregularities before positioning your RV.
Leveling blocks can sink into soft ground, especially after rain or in sandy areas.
Solution: Place a solid base under your blocks to distribute weight more evenly. I use 12"x12" patio pavers under my blocks when camping on soft ground. These pavers provide a stable foundation and prevent sinking.
During a rainy week in Florida, I watched a neighboring RV slowly sink into the soft ground over several days, becoming increasingly unlevel. The owner hadn't used any base material under his jacks or blocks. By the time he noticed the problem, his door was binding in the frame and his refrigerator had shut down.
Sometimes you might find yourself needing more height than your blocks can provide.
Solution: In a pinch, you can use your stabilizing jacks on the low side to slightly lift that corner, then place all available blocks under the wheels. Lower the RV onto the blocks, then properly deploy the stabilizing jacks for their intended purpose.
This is not an ideal long-term solution but can work for a night or two until you can purchase additional blocks.
If your motorhome has hydraulic leveling jacks but they're not functioning properly:
Solution: The Bigfoot Automatic Leveling System offers a reliable replacement that often integrates with existing hydraulic systems. For temporary manual leveling, follow the side-to-side and front-to-back procedures using blocks.
I helped a fellow camper whose hydraulic system had failed mid-trip. Using a combination of Ultra Leveling Blocks and careful positioning, we achieved proper leveling manually until he could get the system repaired.
Over the years, I've heard many misconceptions about RV leveling. Let's address some of the most common myths:
Reality: Even slight leveling issues can cause refrigerator damage over time. Additionally, the stress on your RV's frame and components accumulates, potentially leading to structural problems.
I once spoke with an RV technician who could tell which side of an RV had been consistently unlevel by examining wear patterns on the slide mechanisms—even when the owner wasn't aware of a leveling problem.
Reality: Interior surfaces aren't always parallel to the true frame of the RV. Manufacturing variations, floor flexion, and counter installation can all create misleading readings.
I learned this lesson when I installed my first set of Graduated RV Levels. Despite my interior bubble level showing perfect alignment, the exterior levels revealed I was consistently off by nearly 2 degrees—enough to affect refrigerator performance.
Reality: While manual leveling can achieve the same results with careful effort, automatic systems like the Bigfoot Automatic Leveling System provide consistent precision that's difficult to match manually. For frequent travelers or those with physical limitations, they can be a genuine necessity rather than just a convenience.
Reality: For side-to-side leveling, you should level while still hitched to avoid movement. Only unhitch after achieving side-to-side level, then use the tongue jack for front-to-back leveling.
I've witnessed the consequences of unhitching too early—a trailer rolling off blocks because it wasn't properly secured during the leveling process. Thankfully, no one was injured, but the potential for disaster was significant.
Different RV types require slightly different leveling approaches. Here's what I've learned about each:
Fifth wheels typically require more precise front-to-back leveling due to their design. I've found that small adjustments to the landing gear can make a significant difference in interior comfort.
For motorhomes with hydraulic or automatic leveling systems like the Bigfoot Automatic Leveling System, follow the manufacturer's specific instructions, which typically involve:
Your leveling approach may need to adapt to seasonal conditions:
In hot weather, be mindful of how your RV might settle as asphalt or soft ground warms up. I've had perfectly level setups become noticeably off-kilter by mid-afternoon on hot days.
Check your levels periodically during extreme heat and make adjustments if necessary. The Graduated RV Levels make this quick visual check easy to perform.
In freezing conditions, ground that seems solid can shift as it freezes and thaws. Additionally, snow and ice can melt under your blocks or jacks, causing unexpected settling.
I learned this lesson during an early spring trip when overnight temperatures dropped below freezing. By morning, one side of my RV had settled nearly two inches as the previously muddy ground froze solid in a compressed state beneath my blocks.
For winter camping:
When camping during rainy periods, position your RV with drainage in mind. Even a perfectly level RV can experience problems if it's sitting in a puddle.
I try to maintain a very slight nose-down attitude (less than 1 degree) when heavy rain is expected. This helps water run off the roof toward the back rather than pooling. The precision of the Graduated RV Levels helps achieve this subtle adjustment without affecting appliance operation.
Proper leveling is one of those RV skills that separates seasoned travelers from beginners. It might not be the most exciting aspect of RV life, but it's foundational to comfort, safety, and protecting your investment.
I still think about that night in Colorado when my refrigerator failure taught me the importance of proper leveling. What could have been a costly repair was fortunately just an inconvenient reset procedure, but the lesson was invaluable. Now, achieving precise leveling is the first priority at every campsite, before any other setup tasks.
The products highlighted here—from the Ultra Leveling Blocks to the Bigfoot Automatic Leveling System—represent solutions to real challenges I've encountered during my RV travels. Each addresses a specific aspect of the leveling process, and together they create a comprehensive system for achieving perfect leveling in virtually any situation.
Remember that leveling isn't just about comfort—though sleeping on a level bed is certainly more restful. It's about protecting your refrigerator and other appliances from damage, preventing structural stress on your RV's frame and components, ensuring proper function of drainage systems, and creating a stable living environment regardless of the terrain you're parked on.
With the right equipment, technique, and attention to detail, you can achieve perfect leveling at every campsite, ensuring your RV adventures are comfortable, safe, and free from the kinds of middle-of-the-night surprises that no one wants to experience.
