Stack jacks are designed to provide extra support and stability for your RV, trailer, or camper when parked. By placing them under the frame, they help minimize rocking and movement caused by walking or shifting inside the vehicle.

• They’re adjustable, so you can match the height to uneven ground.
• Aluminum construction makes them lightweight and easy to move.
• Using multiple jacks distributes weight for better balance.

While stack jacks aren’t meant for lifting, they’re a great option for keeping your RV level and comfortable during your stay.

Stack jacks are intended for stabilizing and leveling your RV or trailer, not for lifting vehicles during tire changes.

• They’re designed to support weight and reduce movement, but don’t replace a proper car jack.
• For tire changes, use a dedicated car jack or scissor jack that’s rated for lifting.
• Always follow safety instructions and use the right tool for the job.

Stack jacks are best used for keeping your RV steady when parked, rather than for maintenance tasks like tire changes.

Setting up stack jacks on uneven terrain is simple with a few precautions.

• First, place the jacks under solid points of your RV’s frame.
• Adjust each jack’s height so they make firm contact with the ground.
• If the ground is soft or sloped, use a sturdy board or pad under each jack for extra stability.

Take your time to ensure all jacks are secure and evenly supporting your RV. This helps prevent unwanted movement and keeps your setup safe.

Most stack jacks are rated to support up to 6,000 lbs per jack, but always check the product details for your specific model.

• Never exceed the listed weight capacity.
• Distribute the load across multiple jacks for better stability.
• Stack jacks are for support and leveling, not for lifting the entire vehicle.

Following these guidelines helps keep your RV safe and prevents damage to the jacks or your vehicle.

Stack jacks are compact and easy to store.

• Clean off any dirt or debris before packing them away.
• Collapse or stack them to save space.
• Store them in a dry area, like your RV’s storage compartment or garage, to prevent corrosion.

Keeping your stack jacks clean and dry ensures they’ll be ready for your next adventure and helps extend their lifespan.
