Leveling and stabilizing are related, but they are not the same job. Leveling establishes the RV’s position; stabilizers are generally used to reduce movement after the trailer is properly positioned.
1. Choose the site carefully
Before unhitching, inspect the campsite for slope, soft ground and obstacles. Follow your RV manufacturer’s instructions and use equipment rated for the trailer.
2. Level side to side
For many travel trailers, side-to-side leveling is done while still hitched by positioning appropriate leveling equipment under the low-side tires. Never improvise with unstable materials.
3. Chock the wheels
Secure the trailer against movement using suitable wheel chocks before unhitching, following the RV manufacturer’s sequence.
4. Level front to back
After unhitching, use the tongue jack according to its instructions to bring the trailer level front to back.
5. Stabilize
Deploy stabilizer jacks according to the manufacturer’s procedure. Unless specifically designed and rated for lifting, stabilizers should not be used to lift or level the trailer. Pads can provide a broader footing on appropriate surfaces.
