Why Leveling Your RV Matters
A level RV isn't just about comfort - it's critical for refrigerator operation, slide-out function, door operation, and preventing long-term frame damage. Most RV refrigerators require level within 3° to operate safely. This calculator helps you level quickly and safely.

Leveling Requirements
Step-by-Step Leveling Guide
Check the Site
Before parking, walk the site. Look for low spots, drainage, tree roots, and overhead clearance. Use your bubble level app to check general slope.
Level Side-to-Side First
Always level side-to-side first, then front-to-back. Side-to-side leveling is critical for refrigerator operation. You need 2 blocks for this.
Stack Blocks Securely
Place blocks on solid ground. Stack 2 blocks (2" each = 4" total). Offset seams like bricks. Never exceed 6" total height without extra support.
Drive Up Slowly
Have a spotter guide you. Drive up the blocks slowly in a straight line. Stop when the wheels are centered on the blocks. Use wheel chocks immediately.
Level Front-to-Back
Use tongue jack (trailers) or front jacks (motorhomes) to level front-to-back. Check your bubble level in both directions.
Deploy Stabilizers
Extend all stabilizer jacks until snug (not lifting). Place jack pads under each jack for solid contact with ground.
Final Check
Walk through RV. Check bubble level in multiple locations. Open/close doors and slides. Turn on refrigerator and verify it's level.
Leveling Methods Comparison
Leveling Blocks
Lynx Levelers
Anderson Levelers
Wood Blocks (DIY)
Hydraulic Jacks
Electric Stabilizers
Considering Auto-Leveling?
For your Class C Motorhome, a complete auto-leveling system costs approximately $NaN installed.
Saves 10-15 minutes every setup. Worth it if you move frequently or have mobility concerns.
Common Leveling Mistakes to Avoid
Leveling Front-to-Back First
Always level side-to-side first. Refrigerators are more sensitive to side-to-side leveling.
Stacking Blocks Too High
Never stack more than 6" without support plates. At 4", you're within safe limits.
Forgetting Wheel Chocks
Always use wheel chocks on wheels not on blocks. RVs can roll off leveling blocks.
Using Jacks on Soft Ground
Always use jack pads. Jacks can sink into soft ground, unlevel your RV, and cause frame damage.
Over-Extending Stabilizers
Stabilizers stabilize, not lift. Don't over-extend trying to lift RV - you'll damage the frame.

Frequently Asked Questions
How level does my RV really need to be?
For overnight stays: within 3-4° is acceptable. For extended stays: aim for less than 2°. RV refrigerators require level operation (within 3° side-to-side, 6° front-to-back) or they can be damaged. Slide-outs also function better when level.
Can I use wood blocks instead of plastic levelers?
Yes, 2x6 or 2x8 treated lumber works well. Cut to 12-18" lengths. Wood is cheaper but heavier. Stack with grain perpendicular for strength. Many RVers carry both - plastic for convenience, wood for serious leveling.
What's the maximum safe slope for an RV?
Most manufacturers recommend no more than 6-8% grade (about 3-4°). Beyond 10% is unsafe - risk of tipping, jack failure, and appliance damage. If your site exceeds this, find another spot or reposition your RV.
Should I level before or after extending slides?
Always level BEFORE extending slides. Slides can bind or malfunction if extended on an unlevel RV. Level your RV, deploy stabilizer jacks, then extend slides. Retract slides before moving.
How do I know if my refrigerator is too unlevel?
Check your fridge manual - most require within 3° off level. Signs of problems: not cooling properly, unusual sounds, yellow flame (gas models), or frost buildup. Long-term unlevel operation can permanently damage absorption refrigerators.
Is auto-leveling worth the cost?
If you move frequently (weekly or more), have mobility issues, or camp in challenging terrain, yes. Auto-leveling saves 10-15 minutes and is much easier. For weekend warriors who camp monthly, manual leveling is usually sufficient.
Can I drive on leveling blocks in reverse?
Generally no - most leveling blocks are designed for forward approach only. Driving off in reverse risks damage to blocks and your tires. Some specialty ramps (like Camco Fasten) allow reverse, but check manufacturer specs.
What do I do if the ground is too soft for jacks?
Use larger jack pads or boards under each jack/leveling block. 12x12" plywood works well. In very soft conditions, use 2ft x 2ft pads. Never extend jacks/stabilizers without pads on soft ground - they'll sink and damage your RV frame.
Leveling Tips by RV Type
Class A Motorhomes
- Usually have air suspension - can help with minor leveling
- Most come with built-in hydraulic levelers (if not, retrofit is expensive)
- Heavy weight requires solid ground - always use large jack pads
- Check level before extending slides - they're heavy and can bind
Class B/C Motorhomes
- Lighter weight makes manual leveling easier
- Focus on getting refrigerator side level first
- Use 4-6 leveling blocks typically sufficient
- Front cab can make front-to-back assessment tricky
Travel Trailers
- Disconnect from tow vehicle before leveling
- Level side-to-side first with blocks or jacks
- Use tongue jack for front-to-back leveling
- Deploy stabilizer jacks last - don't use to level
Fifth Wheels
- Level side-to-side before unhitching from truck
- Use truck to help position on blocks
- Auto-leveling systems popular due to weight
- Front landing gear handles front-to-back adjustment
Real Leveling Experiences
Tom M. - Weekend RVer
32' Travel Trailer, 8 years experience
"I learned the hard way about leveling. Camped on a 5° slope without properly leveling. Refrigerator stopped working after 2 days - repair cost $800. Now I never skip leveling, even for one night. I use a smartphone level app and Lynx levelers. Takes 5 minutes, saves thousands."
Lesson: Always level, even for short stays
Jennifer L. - Full-timer
42' Class A, 3 years full-time
"We splurged on auto-leveling when we bought our Class A. Best $8,000 we spent. We move every 1-2 weeks. Press a button, wait 2 minutes, done. No more arguing with my husband about leveling! Worth every penny for full-timers. Manual leveling a 42-footer was exhausting."
Lesson: Auto-leveling worth it for frequent movers
Rick K. - Boondocker
28' Fifth Wheel, desert camping
"Boondocking means uneven terrain. I carry 12 leveling blocks, 4 jack pads, and several 12x12 plywood boards. In sand, I place boards under everything. My system: level side-to-side first, disconnect truck, adjust landing gear for front-to-back. Check level with app in 3 places. Takes 15 minutes, but I sleep soundly knowing I'm safe."
Lesson: Bring extra equipment for challenging terrain
