Few things feel worse than walking around your RV and feeling it rock with every step, or realizing your fridge isn’t quite happy because the rig isn’t level. Learning how to use and maintain RV leveling jacks and stabilizers keeps your coach more solid, protects appliances and slide-outs, and makes camping way more comfortable.
If you’d rather have a technician inspect or repair your leveling system, you can always schedule RV service with the team at Daisy RV.
Why Leveling Matters So Much for Your RV
Getting your RV level isn’t just about comfort or “being picky.” Proper leveling affects:
- Absorption refrigerators – many are designed to operate near level
- Slide-outs – less stress on mechanisms when the frame is straight
- Shower and sinks – better drainage and less chance of standing water
- Doors and cabinets – they close and latch properly
- Overall stability – less rocking and motion sickness inside
That’s why knowing how to use and maintain RV leveling jacks and stabilizers is part of basic RV care, not just a fancy upgrade.
Types of RV Leveling Jacks and Stabilizers
Different rigs use different systems. Knowing what you have is step one.
Manual or Electric Tongue Jacks (Towable RVs)
- Mounted on the A-frame of the trailer
- Raise and lower the front of the trailer
- Used along with wheel chocks and level blocks to get the coach roughly level front-to-back
Scissor or Drop-Down Stabilizer Jacks
- Mounted at the corners of many travel trailers and fifth wheels
- Designed for stabilizing, not lifting the RV
- Can be manual (crank or drill attachment) or electric
Hydraulic or Electric Leveling Jack Systems (Auto-Level)
- Common on motorhomes and higher-end fifth wheels
- Use hydraulic cylinders or heavy-duty electric jacks to lift and level the entire coach
- Often controlled by a touch pad with manual and “auto level” modes
Each style plays a different role in how to use and maintain RV leveling jacks and stabilizers safely.
Step-by-Step: How to Properly Level Your RV
Exact procedures vary by RV, but the basic logic is the same.
1. Start With a Good Parking Spot
- Choose the flattest site you reasonably can
- Avoid big dips or humps under axles or jacks
- Position so slides have space and jacks won’t land in soft mud if possible
A better starting point makes the rest of how to use and maintain RV leveling jacks and stabilizers much easier.
2. Chock Your Wheels First
Before you touch jacks:
- Place wheel chocks snugly against the tires on both sides (for trailers)
- This prevents rolling when you adjust height or unhook the tow vehicle
Chocks are your first safety device. Never rely on jacks alone to keep a rig from moving.
3. Level Side-to-Side
For towable RVs:
- Use leveling blocks or boards under the low-side tires to raise that side
- Drive the trailer or fifth wheel slowly onto the blocks
- Check with a small level (on the floor, countertop, or inside the door)
Motorhomes often use their leveling jacks to do both side-to-side and front-to-back leveling.
4. Level Front-to-Back
For travel trailers:
- Once side-to-side is okay, use the tongue jack to raise or lower the front
- Adjust until the bubble level reads good front-to-back
For fifth wheels:
- Use the front landing gear to set height and unhook the truck, then fine-tune level
For motorhomes with auto-level systems:
- Follow the manufacturer’s sequence (often ignition in ACC, parking brake set, then hit “Auto Level”).
Using Stabilizer Jacks the Right Way
Stabilizer jacks support stability, not weight.
What Stabilizer Jacks Are For
- Reducing movement and wobble when walking around
- Helping the RV feel more “solid” underfoot
- Supporting, not lifting, the rig
What Stabilizer Jacks Are Not For
- They are not designed to lift wheels off the ground
- They should not be used to aggressively compensate for huge uneven sites
- Over-extending them or using them as primary lifting points can bend frames or damage mounts
To use them correctly:
- Place jack pads or blocks under each stabilizer if the ground is soft or uneven.
- Extend the stabilizer until it just contacts the pad.
- Add a little more turn to snug it up, but don’t over-crank it to the point you’re lifting the RV.
That balance is a key part of how to use and maintain RV leveling jacks and stabilizers safely.
Caring for Manual and Electric Stabilizer Jacks
A little maintenance keeps them running smoother for years.
Cleaning and Lubrication
- Periodically wash off dirt, sand, and road grime from jack threads and pivots.
- Use a dry lube or light spray lubricant on screw threads and pivot points (avoid coating everything in heavy grease that traps dirt).
- Wipe off excess so dust doesn’t cake onto the mechanism.
Inspecting for Damage
Look for:
- Bent jack tubes or screw mechanisms
- Loose mounting bolts or cracked welds
- Rust spots that might weaken the structure over time
If you see anything concerning, have a technician at Daisy RV inspect and repair or replace the affected jack.
Maintaining Hydraulic and Electric Auto-Level Systems
Automatic leveling systems are incredibly convenient—but they’re also more complex.
Hydraulic Systems
Key components:
- Hydraulic pump and reservoir
- Steel lines or hoses
- Cylinders at each jack position
- Solenoid valves and control unit
Maintenance basics:
- Periodically check fluid level in the reservoir (use the correct fluid type).
- Inspect for leaks at hose connections, cylinders, and fittings.
- Keep jack rods clean, wiping off mud or road grime that could damage seals.
If jacks start to drift, won’t fully extend/retract, or there’s visible fluid loss, it’s time for professional service.
Electric Systems
Electric jacks rely on:
- 12V power from your house batteries
- Motors and gearboxes at each jack
- Control modules and wiring
Maintenance basics:
- Ensure batteries are healthy—low voltage can cause jacks to stall or error.
- Listen for unusual grinding or straining sounds.
- Inspect wiring and connectors for corrosion or damage.
Any error codes or persistent issues should be diagnosed before continuing heavy use. The crew at Daisy RV can test, calibrate, and repair both hydraulic and electric leveling systems.
Avoiding Common Leveling and Jack Mistakes
A big part of how to use and maintain RV leveling jacks and stabilizers is avoiding the classic “don’ts.”
Lifting Wheels Off the Ground
- Completely lifting wheels (especially on trailers) can reduce stability and stress the frame.
- You generally want tires in solid contact with the ground, with jacks supporting the frame—not carrying everything alone.
Using Jacks on Very Soft Ground Without Pads
- Jacks can sink into soft soil, gravel, or hot asphalt.
- Always consider using jack pads or blocks to spread the load and keep jacks stable.
Running Jacks With a Weak Battery
- Low voltage causes slow or jerky motion, incomplete extension, and error faults.
- If power seems weak, charge the batteries or connect to shore power before operating jacks.
Retracting With Slide-Outs in the Wrong Order (On Some Rigs)
Some manufacturers specify:
- Slides in, then level or
- Level first, then slides out
Follow your owner’s manual sequence. Getting this wrong can stress both slide mechanisms and jacks.
Storing and Traveling With Jacks and Stabilizers
Good habits here prevent damage and noise on the road.
- Always fully retract leveling jacks and stabilizers before traveling.
- Double-check visually that nothing is hanging low enough to catch on speed bumps or curbs.
- If your jacks have rubber feet or pads, inspect them occasionally for wear or cracking.
- For manual systems, store crank handles or drill attachments where they’re easy to reach when you arrive at camp.
A quick walk-around before leaving a site is cheap insurance against expensive jack or frame repairs.
When to Get Professional Help With Your Leveling System
You should have a technician take a look if:
- Jacks are bent, slow, or noisy
- You see hydraulic fluid leaks or oil on the jacks
- The system shows error codes or refuses to complete a level cycle
- The RV never feels stable, even when you think you’ve done everything right
- The frame creaks or pops dramatically when leveling
A pro can:
- Inspect and adjust jack mountings and alignment
- Service hydraulic pumps and cylinders or electric motors
- Check battery health and wiring feeding the leveling system
- Teach you a leveling process tailored to your specific rig
If your jacks or stabilizers are already acting up, getting them checked at Daisy RV before your next big trip can save you from battling a stuck or broken jack at a campsite.
Understanding how to use and maintain RV leveling jacks and stabilizers turns setup from a stressful guessing game into a quick, repeatable routine. With good chocking, proper leveling sequence, regular cleaning and lubrication, and the right respect for the limits of your equipment, your RV will sit solid, level, and comfortable wherever you park it.
