After your RV is leveled, you’ll want to stabilize it so it doesn’t rock back and forth when you walk around inside. You should use stabilizing jacks to accomplish this.
Note: These should never be used to level a rig, as they weren’t designed for that purpose.
Stabilizing jacks come in several configurations. The most common is the scissor jack, which is usually bolted or welded to the trailer’s frame at the front and rear.
Pop-up tent trailers are frequently equipped with a drop-down style jack, which, as the name implies, drops down from the frame.
To use the stabilizing jacks after you’ve leveled the RV:
1. Lower the jacks following the manufacturer’s instructions. To save time and give the foot of each jack a larger base, slide a couple of short 2×4- or 2×6-inch boards beneath each foot. This is especially helpful if the ground is loose or sandy.
2. Once the jack foot is in contact with the ground, give the crank a few extra turns to provide the trailer a secure footing. Check the bubble level to make sure your RV remains level. Do this for all four corners.
