Auto-Leveling System
A push-button hydraulic leveling system that automatically deploys jacks to level the RV at the campsite. Standard on most Class A motorhomes.
Also called: auto-leveling, automatic leveling, hydraulic auto-level, push-button leveling
An auto-leveling system is a push-button hydraulic leveling system that automatically deploys jacks to level the RV at the campsite. Standard on most modern Class A motorhomes and increasingly common on larger Class C rigs.
How it works
- Park on the most level ground available
- Engage parking brake
- Press the auto-level button
- System extends jacks in sequence to level the rig
- Indicator shows level achieved
- Hydraulic pump continues to maintain level
- At departure: press retract button to lift jacks before driving
The whole process takes 1-3 minutes typically.
Safety considerations
Before activating
- Verify no obstacles under or beside the jacks
- Ensure no people or pets near the jacks
- Check ground stability (very soft ground requires blocks under jacks)
- Confirm parking brake engaged
During operation
- Don’t move inside the rig while leveling (changes weight distribution)
- Don’t deploy slide-outs until leveling complete
- Listen for unusual sounds (slow hydraulics indicate fluid leak)
Before retracting
- Retract slide-outs first
- Close door, secure interior
- Verify no one is near jack locations
- Confirm parking brake engaged
Auto-level vs. manual jacks
| Auto-leveling | Manual jacks | |
|---|---|---|
| Convenience | Push button | Crank each jack |
| Time | 1-3 minutes | 10-20 minutes |
| Common in | Class A, larger Class C | Travel trailers, fifth wheels, older rigs |
| Failure mode | Electronic + hydraulic | Mechanical, simpler |
Auto-leveling is luxury at the rental level. Most renters appreciate it; some prefer manual control for steep terrain.
Common failure modes
- Hydraulic fluid leak — jacks slow or won’t lift
- Solenoid failure — buttons don’t activate
- Battery drain — hydraulic pump won’t operate
- Sensor failure — system can’t detect level
Renter precautions
- Test the system during walkthrough — extend and retract
- Confirm fluid level in the reservoir
- Note operating sound to detect changes
- Know the manual override in case of electronic failure
- Confirm jacks fully retracted before driving
What if it fails mid-trip
Most auto-leveling systems have a manual override:
- Individual jack control buttons (rather than auto)
- Sometimes a manual pump handle
- Emergency retract that uses gravity if the system fails
The walkthrough should cover these alternatives. Take notes during pickup.
Driving with jacks deployed
Most modern RVs prevent this electronically — won’t start the engine until all jacks confirm retraction. But some older systems can be tricked.
Always do a walk-around inspection before driving away from a campsite. Verify all 4 jacks are fully up.
Block requirements
On soft ground, jacks need additional support:
- Plastic leveling blocks (typically 4-piece set)
- Wooden boards (2x10 cut to size)
- Specifically designed blocks for the rental
If you’ll be camping on dirt/grass, ask the rental company about provided blocks or buy a set at any RV store ($30-$60).
