An RV can be perfectly level and still move when someone walks, turns in bed, or climbs the steps. That happens because leveling and stabilization solve different problems: leveling corrects side-to-side and front-to-back angle, while stabilizing reduces suspension and frame movement.
Start with a firm foundation
Park on the firmest available surface. Soft soil, loose gravel, and wet ground allow tires, jacks, and blocks to settle. Use load-rated pads or blocks large enough to spread the weight, and never exceed the equipment manufacturer’s limits.
Chock the wheels correctly
Chock the wheels before unhitching. On tandem-axle trailers, properly fitted between-the-wheel chocks can reduce fore-and-aft tire movement. Standard ground chocks remain important and should be used as directed.
Use stabilizer jacks for stabilization
Extend stabilizer jacks until they make firm contact, then apply only the amount of tension recommended by the RV manufacturer. Most stabilizer jacks are not designed to lift or level the RV. Overextending them can reduce rigidity and damage equipment.
Keep extensions short
Use approved blocks under stabilizers so the jack does not need to extend as far. A shorter extension is generally more stable, but blocks must be strong, flat, correctly positioned, and rated for the load.
Check common movement sources
- Unchocked or poorly chocked wheels
- Loose stabilizer feet on uneven ground
- Long jack extensions
- Flex in entry steps
- Fifth-wheel pin-box movement
- Slide-out movement
- Settling pads after rain or temperature changes
Add purpose-built stabilization if needed
Depending on the RV, cross-brace stabilizers, tripod systems, slide-out stabilizers approved by the manufacturer, or step supports may help. Confirm compatibility and never use an accessory that transfers loads to a component not designed to carry them.
Recheck after setup
Walk through the RV, inspect every contact point, and recheck the setup after the first few hours. If a jack repeatedly loses contact or the RV shifts, reposition on firmer ground and inspect the equipment before continuing.
