6 Best RV Jacks For Storage That Prevent Costly Repairs

Parking your RV for the season seems simple enough, but letting it sit for months on its tires is a slow-motion disaster for your suspension and frame. Many owners don’t realize that the very thing designed for movement—the tire and suspension system—is what suffers most from standing still under thousands of pounds of static load. The right set of storage jacks isn’t just an accessory; it’s a crucial piece of preventative maintenance that separates a well-cared-for rig from one facing a spring full of costly repairs.

Why RV Storage Jacks Protect Your Investment

Letting an RV sit on its tires for an entire offseason is one of the most common mistakes I see. Your tires aren’t designed to hold the full, concentrated weight of your rig in one spot for months. This leads to flat spots, weakened sidewalls, and premature cracking, forcing you to replace expensive tires far sooner than you should.

But the damage goes deeper than the rubber. The entire suspension system—leaf springs, shocks, and axles—remains under constant, unmoving tension. This sustained load can cause springs to sag and lose their resilience. Over time, this stress can even transfer to the RV’s frame, leading to subtle warping that causes issues with slide-outs, doors, and overall structural integrity.

Storage jacks solve this by becoming the RV’s skeleton while it hibernates. By placing jacks at strategic points along the frame, you transfer the rig’s weight off the suspension and tires and onto the solid jacks. This allows the suspension to relax and the tires to hold only their own shape, not the weight of a house. It’s a simple action that prevents a cascade of expensive, long-term problems.

Eaz-Lift Scissor Jacks: A Versatile Option

When you need a reliable, no-nonsense solution, the Eaz-Lift Scissor Jack is a classic for a reason. These jacks are workhorses, built from heavy-duty steel with a wide, stable base that prevents them from sinking into soft ground like gravel or asphalt on a hot day. Their simple screw mechanism is robust and easy to operate.

Their true value lies in their versatility. Available in various weight capacities (typically 24" or 30" models with 5,000 lb ratings), they can handle everything from a small travel trailer to a mid-size fifth wheel. While their primary job is long-term stabilization, they’re also sturdy enough to help you with a roadside tire change in a pinch. You’re getting more than just a storage tool.

The main tradeoff is the manual operation. Using the included hand crank can be a bit of an arm workout, especially when you’re setting up four of them. However, most people use a simple adapter that lets them raise and lower the jacks in seconds with a cordless drill. This small accessory turns a chore into a quick and easy task.

Camco Olympian Aluminum Stack Jacks: Lightweight

If you’re piloting a lighter pop-up camper or a small travel trailer, or if storage space in your tow vehicle is at a premium, the Camco Olympian Stack Jacks are a fantastic choice. Made entirely of cast aluminum, they are incredibly lightweight and easy to handle. You can carry all four at once without breaking a sweat.

Their design is simple and effective: a central screw raises and lowers the support pad. When you’re done, they nest inside each other, taking up a minimal amount of space in a storage bay or garage. This makes them ideal for anyone who wants a solution that is as easy to store as it is to use.

The key consideration here is their capacity. While each jack is rated for 6,000 lbs, their lightweight construction makes them better suited for stabilizing and taking a partial load off lighter rigs. For a heavy fifth wheel, I’d use these to supplement beefier jacks for added stability, not as the primary load-bearing supports. They excel at preventing sway but aren’t the best choice for lifting a 12,000 lb rig completely off its suspension.

LIBRA TRUE 7500 lb Heavy-Duty Scissor Jacks

For owners of heavier travel trailers and fifth wheels, there’s no room for compromise. The LIBRA TRUE Heavy-Duty Scissor Jacks are built for exactly this scenario. With a massive 7,500 lb capacity per jack, a set of four provides a 30,000 lb support system, which is more than enough for the vast majority of towable RVs on the market.

What sets these apart is the robust construction. They use thick-gauge steel and a rust-inhibitive coating that stands up to the elements during long, wet winters. The wide bow-tie base provides a solid footing on various surfaces, which is critical when you’re trusting them with the full weight of your investment. This isn’t just a jack; it’s peace of mind.

These are an upgrade in every sense. They are heavier and bulkier than standard-duty jacks, but that’s the price of security. If you have a rig that’s pushing the limits of standard 5,000 lb jacks, investing in a set of LIBRA jacks is a smart move. You’ll feel the difference in stability the moment you set them.

BIG RED Torin Steel Jack Stands: Max Support

Sometimes, the best tool for the job isn’t a jack at all—it’s a jack stand. The BIG RED Torin Steel Jack Stands represent the gold standard for secure, long-term support. It’s important to understand their function: you use a separate bottle or floor jack to lift the RV, then place these stands under the frame to hold the weight. They are for holding, not lifting.

Their strength is in their simplicity and safety. A forged steel ratchet bar locks into place with a satisfying clunk, creating a fail-safe support that cannot slip or slowly lower over time like a hydraulic jack might. This is the same technology mechanics trust their lives to when working under a vehicle, and it provides unmatched stability for a stored RV.

This is the solution for the owner who wants absolute, unquestionable security. It’s a two-step process that takes a few extra minutes, but the result is a rock-solid rig that won’t budge. For very heavy fifth wheels or for anyone who might be doing maintenance under the rig during storage, using jack stands is the safest and most reliable method.

BAL Light Trailer Stabilizing Jacks: C-Jack

The BAL C-Jack is a common sight, often found permanently mounted to the corners of light and mid-weight travel trailers. Their primary design purpose is right in the name: stabilizing. They are fantastic at eliminating the side-to-side and front-to-back motion that makes a parked RV feel wobbly.

While they do take some of the load off the suspension, they aren’t designed to lift the entire weight of the rig off the tires. Their C-shaped channel design is excellent for triangulation and preventing movement, but it’s not as robust for pure vertical lifting as a scissor jack or jack stand. Think of them as braces, not pillars.

These are a great option if your main goal is to stop the rig from rocking in the wind or when you walk around inside during storage. They can be used on their own for lighter trailers or, in a perfect world, used in conjunction with other jacks placed closer to the axles to handle the heavy lifting. This combination provides both vertical support and lateral stability.

Stromberg Carlson J-2000 Jack-in-a-Box Kit

For the RVer who wants a straightforward, effective solution without over-analyzing a dozen different options, the Stromberg Carlson Jack-in-a-Box kit is perfect. It’s an all-in-one package that includes two high-quality, 5,000 lb capacity scissor jacks and the crank handle to operate them. You just buy two boxes, and you’re ready to go.

These are well-made, standard-duty jacks with a durable black powder-coat finish to resist rust. They feature the same reliable screw-type mechanism and stable base as other top scissor jacks. The convenience of the kit removes the guesswork and ensures you have everything you need to get the job done right out of the box.

This kit is an excellent choice for most travel trailers and smaller fifth wheels. It strikes a great balance between capacity, durability, and ease of use. It’s a trusted name in the RV industry, and this product delivers on that reputation by providing a simple, reliable way to protect your rig’s tires and suspension during storage.

How to Choose the Right RV Jack for Your Rig

Picking the right jack isn’t complicated, but it requires you to get a few key details right. Don’t just buy the first thing you see online. Your decision should be based on your specific rig and your needs.

First and foremost, know your RV’s weight. Look for the Gross Vehicle Weight Rating (GVWR) on the sticker on the side of your rig. Your jacks’ total capacity should comfortably exceed this number. A good rule of thumb is to ensure each jack can handle at least half of your trailer’s total weight, giving you a massive safety margin. Never skimp on weight capacity.

Next, consider the type of support you need.

• Scissor Jacks: The best all-around choice for lifting and stabilizing. Great for most users.
• Stack Jacks: Ideal for lightweight applications where portability and small storage size are priorities.
• Jack Stands: The ultimate choice for maximum safety and long-term stability, especially for heavy rigs. Requires a separate jack for lifting.
• Stabilizing Jacks (C-Jacks): Best for eliminating wobble and sway, but less suited for bearing the full vehicle weight.

Finally, think about the material and ease of use. Steel is stronger and more durable but requires a good coating to prevent rust. Aluminum is lightweight and won’t rust but may have lower capacity. And be honest with yourself about operation—if you don’t want to hand-crank, make sure you get a jack that works with a power drill adapter.

Ultimately, a set of quality storage jacks is a small investment that pays huge dividends by protecting your tires, suspension, and frame from the relentless strain of static weight. It’s one of the simplest and most effective things you can do to ensure your RV is ready to hit the road when adventure calls, not stuck in a shop with avoidable and expensive repairs. Choose the right tool for your rig, and you can rest easy knowing your investment is secure.
