9 Durable Storage Solutions for Heavy Camper Leveling Blocks and Chocks for Full-Time RVers

Pulling into a dream campsite after a long day on the highway is one of the best parts of RV living, but that excitement quickly fades when you have to retrieve mud-caked leveling blocks from a cramped storage bay. Heavy plastic blocks, rubber wheel chocks, and curved leveling ramps are essential for stabilizing your rig, but they are notoriously dirty and awkward to pack away. Having a dedicated, ultra-durable storage solution for this heavy gear keeps your rig clean, organized, and ready for quick setups on any terrain.

Managing the Weight and Mud of RV Leveling Gear

Full-time RV living exposes your gear to the elements, and nothing bears the brunt of this quite like your leveling blocks and wheel chocks. Placing hundreds of pounds of trailer weight onto plastic or wood resting on wet clay, gravel, or damp grass guarantees one thing: mud. Stashing these items directly into your carpeted pass-through compartment or under-bed storage leads to abrasive grit, unpleasant odors, and moisture issues that can rot your rig’s interior over time.

Beyond the mess, the physical weight of high-quality leveling gear presents a structural challenge. Heavy-duty rubber chocks and thick leveling blocks can easily add up to 30 or 50 pounds of dense, concentrated weight. If this gear isn’t secured in a dedicated containment system, it will slide during transit, acting like a battering ram against delicate water lines, electrical wiring, or lightweight interior bay walls.

The key to a successful storage strategy is isolating this gear while keeping it highly accessible. You need materials that resist punctures from sharp gravel embedded in rubber, can handle frequent washdowns, and provide adequate ventilation to dry out wet items. Setting up a systematic way to manage this heavy, dirty gear is a baseline requirement for maintaining sanity on the road.

Heavy-Duty Storage Bag – Camco Utility Block Bag

When using interlocking plastic leveling blocks, storing them loosely is a recipe for clutter and cracked plastic. A dedicated storage bag keeps your blocks stacked tightly, preventing them from scattering across your storage bay while keeping dirt and residual moisture contained. It makes grabbing your entire leveling setup as simple as lifting a single handle, streamlining the arrival process at a new site.

The Camco Utility Block Bag stands out because it is custom-sized to hold up to ten standard 1.5-inch thick interlocking blocks. It features a rugged zippered top and a mesh top panel that allows damp blocks to breathe, reducing the chance of mold growth inside the bag. The heavy-duty polyester construction resists tearing when loaded with heavy, sharp-edged blocks, and the durable webbed handles make transport comfortable.

Before buying, note that this bag is designed specifically for standard 8.5″ x 8.5″ square blocks; oversized or extra-wide blocks from other brands will not fit. Additionally, while the mesh top allows airflow, it also means muddy water can drip through if you pack the blocks completely wet, so shaking them off first is highly recommended.

This bag is ideal for RVers who rely on standard Camco or Lynx leveling blocks and want a low-cost, space-efficient way to keep them organized. It is not the right choice for heavy, curved drive-on levelers or oversized rubber wheel chocks, which require a much larger footprint.

Rugged Storage Bin – Rubbermaid ActionPacker 8-Gal

For those who want absolute containment of mud and water, a heavy-duty hard plastic bin is the gold standard. Bins allow you to toss muddy leveling blocks and wet rubber chocks directly inside without worrying about liquid leaking onto your RV’s bay floors. They also stack easily, allowing you to optimize vertical space in deep storage compartments.

The Rubbermaid ActionPacker 8-Gal is the ultimate choice for this task due to its impact-resistant construction and lockable latches. Unlike cheap home storage bins that crack under the weight of heavy rubber chocks when temperatures drop, the ActionPacker handles extreme cold and rough transit without breaking. Its compact footprint fits perfectly into most pass-through bays while holding a surprising amount of gear:

• Capacity: 8 gallons / 30 liters
• Secure Latches: Heavy-duty, lockable metal latching lid keeps contents secure
• Tough Exterior: Impact-resistant frame resists scratches and drops

Keep in mind that the rugged, double-walled lid design reduces the usable interior height slightly at the edges. You will need to stack your blocks strategically to ensure the lid latches completely. Because this bin is airtight when latched, storing soaking wet blocks inside for long periods will cause mildew unless you crack the lid open to dry.

This bin is perfect for RVers seeking a bulletproof, stackable container that can live in a pass-through bay or an open truck bed. It is not ideal for those with extremely shallow storage bays where every vertical inch counts.

Leveler Carrying Bag – Andersen Hitches 3612 Bag

Curved drive-on levelers are incredibly popular for quick trailer leveling, but their awkward crescent shape makes them difficult to pack neatly. Without a dedicated bag, these curved ramps roll around, take up excessive horizontal space, and coat neighboring gear in dirt. A specialized carrying bag solves this by wrapping the levelers in a snug, compact footprint.

Designed specifically to house two curved levelers and their accompanying chocks, the Andersen Hitches 3612 Bag is built from heavy-duty, puncture-resistant canvas. It features a rugged zipper that wraps around the bag for easy loading and a sturdy carrying strap that simplifies transport to and from your trailer wheels. The material is thick enough to prevent the sharp edges of the levelers from wearing through the fabric over years of use.

While this bag is engineered for the Andersen Camper Leveler system, it can also accommodate some third-party curved levelers of similar dimensions. However, check your leveler measurements carefully before purchasing, as extra-wide or oversized curved ramps will stretch the seams or prevent the zipper from closing.

This is a must-have for owners of the Andersen curved leveling system who want to keep their ramps clean and compact. It is not suitable for square interlocking blocks or oversized, heavy industrial wheel chocks.

Underbody Toolbox – Buyers Products Steel Box

Keeping wet, dirty leveling gear entirely out of your RV’s living space and main storage bays is the ultimate goal for many full-timers. Mounting an external underbody toolbox directly to your trailer chassis or truck frame provides instant access to your gear exactly where you need it—outside. It frees up premium interior space for items that actually need to stay climate-controlled.

The Buyers Products Steel Underbody Toolbox is built like a tank, featuring 14-gauge steel construction and a powder-coat finish that resists rust and road debris. The door is sealed with a weather-resistant neoprene gasket and secured by a stainless steel T-handle latch, ensuring your heavy gear stays dry and locked away. This box is tough enough to withstand rocks kicked up by your tires without denting or leaking:

• Materials: Durable 14-gauge steel with gloss black powder coat
• Sealing: Watertight compression latch system and neoprene gasket
• Door Support: Aircraft-grade cable door supports to handle rough drops

Installing this box requires professional mechanical skills or fabrication, as you must bolt or weld heavy-duty mounting brackets directly to your rig’s frame. You also need to calculate the added tongue weight or rear-end weight to ensure it does not negatively impact your towing dynamics.

This solution is ideal for dedicated DIYers and full-time RVers with large trailers or flatbeds who want to isolate dirty gear completely. It is not suitable for lightweight travel trailers or those who want a simple, no-tool installation.

Sliding Cargo Tray – MORryde Sliding Storage Drawer

Crawling into a deep pass-through storage bay to retrieve a heavy stack of blocks at the very back is a recipe for back strain. A sliding cargo tray mounts directly to your bay floor, allowing you to pull your entire inventory of blocks and chocks out into the light with minimal effort. It maximizes the utility of deep compartments that are otherwise hard to reach.

The MORryde Sliding Storage Drawer features a heavy-duty steel frame and ball-bearing glides that deliver smooth operation even when loaded with hundreds of pounds of gear. It comes fully assembled and features a two-way travel slide that allows you to access your gear from either side of your RV’s pass-through bay. The rugged finish handles muddy blocks without staining, and the integrated latch locks the tray securely during travel.

Remember that these sliding trays take up about two to three inches of vertical storage space due to the mounting tracks and tray lip. You must measure your bay opening height carefully to ensure your tallest blocks will still fit once the tray is installed.

This is the perfect upgrade for fifth-wheel or large travel trailer owners who want effortless access to heavy leveling gear. It is not a good fit for small camper vans or rigs with shallow, exterior-access compartments.

Bumper Cargo Tray – Mount-n-Lock GennyGo Carrier

When interior storage space is at a premium, moving your heavy leveling blocks to the rear bumper is a smart space-saving move. An external bumper tray provides a dedicated outdoor platform where wet gear can drip-dry naturally without ever entering your rig. This keeps the mess outside where it belongs and simplifies campsite setups.

The Mount-n-Lock GennyGo Carrier is designed specifically to mount on standard 4-inch square RV bumpers using high-strength steel brackets. Its aluminum tray construction keeps the carrier itself lightweight while providing a rust-free platform that easily supports heavy bins filled with leveling blocks. The slotted design allows rainwater and road grime to drain away instantly, and the high sidewalls keep your storage bins from sliding off during transit.

Standard RV bumpers are notorious for weak welds, so it is highly recommended to install the Mount-n-Lock SafetyStruts bumper brackets alongside this tray to prevent bumper failure under load. Ensure you secure your storage bins to the tray using heavy-duty ratchet straps or lockable cables to prevent theft.

This tray is ideal for travel trailer and fifth-wheel owners looking to free up interior bay space by moving heavy gear to the bumper. It is not recommended for rigs without a sturdy, square rear bumper or those already towing a rear mount rack.

Heavy-Duty Duffel – Rothco Canvas Cargo Bag

If you prefer a flexible, lightweight container that conforms to odd spaces, a heavy-duty canvas duffel bag is an excellent choice. Unlike rigid plastic bins, a canvas bag can squeeze into tight, irregular storage nooks when it is not fully loaded. It offers a classic, durable way to keep blocks grouped together without adding unnecessary bulk or weight.

The Rothco Canvas Cargo Bag is built from 21-ounce 100% cotton canvas, making it incredibly resistant to punctures from sharp rubber chocks or plastic block edges. It features a brass zipper with a snap-down storm flap that keeps dust and moisture out, alongside reinforced webbed carry handles that wrap around the bottom of the bag to support heavy loads. The breathable nature of natural canvas allows trapped moisture to evaporate slowly, preventing the stale odor common to plastic bags.

Because canvas is water-absorbent, this bag should not be set down on wet mud or grass, as it will soak up moisture and transfer it to your storage bay floor. It is best used as a dry-storage liner for clean or dry blocks inside a pass-through compartment.

This duffel is perfect for RVers who want a tough, flexible, and classic storage bag that can handle heavy weight without ripping. It is not suitable for storing soaking wet, muddy blocks that need to be put away immediately in a wet climate.

Spare Tire Bag – Trasharoo Heavy Duty Utility Bag

Utilizing the space on your exterior spare tire is one of the most efficient storage hacks in the alternative living world. An exterior tire bag keeps your muddy leveling blocks, chocks, and recovery gear completely outside your living space. It is incredibly easy to reach, meaning you can level your rig and chock your wheels without ever opening an interior hatch.

The Trasharoo Heavy Duty Utility Bag is a legendary overland accessory made from 900-denier nylon with a water-resistant interior coating. It buckles securely around any 29-inch to 40-inch spare tire using heavy-duty wide straps and nylon buckles. The bottom of the bag features drain grommets that allow water to escape, making it the perfect place to drop muddy blocks directly after a rainy packing session:

• Material: Rugged 900D nylon construction with double-stitched seams
• Fitment: Fits spare tires from 29 inches up to 40 inches
• Drainage: Built-in drainage grommets for wet gear at the bottom

Prolonged exposure to intense UV rays will eventually fade the nylon fabric, so treating it with a UV protectant spray once a season will extend its lifespan. Additionally, make sure your spare tire mount is rated to handle the extra weight of the bag plus 30 to 40 pounds of leveling gear.

This bag is the absolute best choice for camper vans, overland rigs, and travel trailers with a rear-mounted spare tire. It is not suitable for rigs that lack an exterior-mounted spare tire or those with covered tire carriers.

Stackable Utility Crate – SidioCrate Modular Box

Finding a storage solution that offers the rigidity of a plastic bin with the visibility and airflow of a basket can be tough. Heavy utility crates solve this dilemma by providing solid structural walls that can be stacked high without collapsing. They keep your gear organized while allowing you to see exactly what is inside at a glance.

The SidioCrate Modular Box takes the classic milk crate design and upgrades it with structural HDPE plastic construction and integrated divider slots. These slots allow you to slide in dividers to separate dirty rubber chocks from cleaner plastic leveling ramps. The ventilated open-grid design provides maximum airflow so wet blocks can dry out completely while stacked neatly in your storage bay.

Because the walls are open-grid, dirt and water will shake out of the bottom of the crate onto whatever surface it sits on. If you store this inside a carpeted bay, you will want to place a rubber cargo mat underneath the crate to catch falling debris and moisture.

This crate is ideal for organized RVers who want a stackable, modular system with excellent ventilation for their pass-through bays. It is not suitable for those who want a completely sealed, dust-proof, and waterproof containment system.

How to Prevent Mold and Odor in Wet RV Storage

Putting away leveling gear while it is still wet is often unavoidable when a storm rolls in on departure day. However, trapping that moisture inside a dark, sealed RV storage compartment is a recipe for black mold, mildew, and foul odors that can penetrate your living space. Moisture also degrades the strength of canvas bags and rusts the metal components of your jack pads and chocks.

To combat this, always prioritize ventilation by choosing storage containers with mesh panels, drainage grommets, or open-grid walls. If you must use airtight bins like the ActionPacker, leave the lid slightly unlatched once you arrive at your next destination to let trapped humidity escape. Adding a few reusable silica gel desiccant packs or a hanging moisture absorber bag like DampRid inside your storage bay can also make a massive difference.

Finally, get into the habit of giving your leveling blocks a quick hose-down before packing them away for long travel days. Removing the organic mud and grass prevents bacteria from thriving in the damp, dark environment of your bays. A clean, quick wipe with a rag before storing will save you hours of scrubbing moldy plastic later on.

Weight Distribution Tips for Heavy Leveling Gear

When packing your RV, it is easy to forget how quickly the weight of leveling blocks, wheel chocks, jack pads, and leveling ramps adds up. Placing all of this heavy gear at the extreme front or rear of your trailer can drastically alter your tongue weight and towing stability. Improper weight distribution can lead to dangerous trailer sway on the highway or put undue stress on your tow vehicle’s suspension.

Ideally, heavy leveling gear should be stored as close to the RV’s axles as possible to minimize its rotational leverage on the chassis. If you must store it in a front pass-through bay, balance that weight by placing lighter items on the opposite side or adjusting your cargo layout. Never overload a rear bumper cargo tray beyond its rated capacity, as excess weight at the rear lightens your tongue weight and invites dangerous swaying.

Always weigh your rig periodically at a scale to ensure you remain within your Gross Vehicle Weight Rating (GVWR) and axle capacities. Keeping your heaviest blocks and chocks stored low to the ground also helps maintain a low center of gravity, improving overall handling on winding mountain roads.

Conclusion

Investing in a dedicated, heavy-duty storage solution for your RV leveling gear is more than just an organizational choice—it is a smart way to protect your rig’s interior from moisture and structural damage. Whether you choose a rugged exterior spare tire bag or a heavy-duty sliding bay drawer, isolating your muddy blocks and heavy chocks makes campsite setups smoother and cleaner. Pick the solution that matches your towing setup, keep your gear clean, and enjoy a much more efficient transition at your next destination.
