The Reality of Managing Muddy Leveling Gear on the Road

Full-time RV living exposes you to every imaginable terrain, from sandy beaches to clay-heavy forest floors. Leveling blocks and wheel chocks are your first line of defense against a sloped, unstable rig, meaning they bear the brunt of this outdoor debris. Tossing them directly into your main pass-through storage bay without a plan quickly spreads dirt, grit, and moisture to your clean camping gear, hoses, and power cords.

Moisture trapped in dark, unventilated RV compartments is a recipe for mold, mildew, and rot. Standard plastic blocks feature hollow honeycomb designs that excel at trapping mud, standing water, and tiny critters inside their crevices. Without a dedicated containment strategy, you will find yourself dealing with persistent musty smells and ruined gear inside your limited storage spaces.

Resolving this daily headache requires a system that isolates the dirt while remaining easily accessible during setup and teardown. The ideal storage solution depends on your rig’s layout, available bumper space, and whether you prefer interior containment or exterior mounting. Choosing the right gear ensures that breaking camp remains a fast, stress-free process, even after a heavy downpour.

Leveling Block Bag – Camco Utility Block Storage Bag

A dedicated zipper bag serves as the first line of defense for interior storage bays by containing loose dirt and residual moisture. Instead of letting dirty blocks rattle around loose, a bag consolidates them into a single grab-and-go package. This keeps your pass-through storage tidy and prevents heavy plastic blocks from damaging softer cargo during transit.

The Camco Utility Block Storage Bag is specifically engineered to handle the unique shape and weight of heavy leveling blocks. Made from heavy-duty, water-resistant polyester, it features a wrap-around zipper that allows the bag to open fully for hassle-free loading. The mesh top panel is a crucial feature, allowing trapped moisture to evaporate rather than stewing in a sealed environment.

This bag is sized perfectly to fit standard 10-inch by 10-inch interlocking leveling blocks, holding up to ten blocks securely. However, because of the mesh top, this bag is not 100% waterproof; it is designed for covered storage bays rather than open-air bumper mounts. If your blocks are caked in thick, wet mud, you must let them dry or shake off the worst of the debris before zipping them inside.

• Dimensions: 12″ x 12″ x 10″
• Capacity: Up to 10 standard square leveling blocks
• Material: Heavy-duty polyester with a breathable mesh top
• Best for: RVers who store their blocks inside pass-through compartments and want to contain dry dirt.
• Not for: External mounting in direct rain or holding soaking wet, dripping mud.

Heavy-Duty Tote – Rubbermaid ActionPacker 8-Gallon Bin

When dealing with dripping wet, clay-caked blocks, fabric bags can leak moisture onto your storage bay floor. A heavy-duty plastic tote provides an absolute barrier, keeping water, mud, and road grime completely isolated from your RV’s interior. These rugged bins can handle the abrasive scraping of plastic and rubber chocks without cracking or wearing down over time.

The Rubbermaid ActionPacker 8-Gallon Bin is legendary in the mobile living community for its near-indestructible construction and secure latching lid. Its compact footprint fits easily into most standard RV basement compartments, while the lockable latches keep the lid tightly sealed against shifting cargo. The tough impact-resistant plastic withstands extreme temperature swings, preventing it from becoming brittle in freezing weather or soft in summer heat.

Because this bin is airtight when latched, storing damp blocks inside for extended periods will cause mold and unpleasant odors. You will need to wipe down your gear or leave the lid cracked once you reach your next dry destination. Its rigid structure also means it takes up a fixed amount of space in your bay, whether it is completely full or entirely empty.

• Capacity: 8 Gallons (approx. 30 Liters)
• Dimensions: 19.9″ x 14.1″ x 12.1″
• Key Feature: Lockable latching lid with impact-resistant frame
• Best for: Harsh climates and RVers who need 100% leakproof containment in their basement bays.
• Not for: Tight storage spaces where a flexible, collapsible container is required.

RV Bumper Carrier – Stromberg Carlson Cargo Carrier

The absolute best way to manage dirty leveling gear is to keep it entirely outside the living and storage areas of your RV. A bumper-mounted cargo carrier shifts the mess outdoors, allowing wind and rain to naturally clean and dry your blocks during transit. This frees up valuable interior basement space for items that actually need to stay dry and climate-controlled.

The Stromberg Carlson Cargo Carrier mounts directly to standard 4-inch square RV bumpers, providing a robust, steel mesh platform for dirty gear. Its steel construction handles heavy loads up to 200 pounds, making it ideal for heavy rubber chocks, leveling ramps, and wooden blocks. The open mesh floor prevents standing water from pooling, allowing dirty gear to drain completely onto the road below.

Adding weight to the rear bumper of a travel trailer or fifth wheel can impact tongue weight and towing stability if not balanced correctly. You must verify your bumper’s weld strength before loading it up, as some lightweight travel trailer bumpers require aftermarket support brackets. Additionally, you will need heavy-duty bungee cords or ratcheting straps to keep your blocks locked down over bumpy highway miles.

• Dimensions: 60″ x 20″ platform
• Weight Capacity: Up to 200 lbs
• Compatibility: Fits standard 4″ square RV bumpers
• Best for: Travel trailers and fifth wheels with strong rear bumpers looking to maximize interior space.
• Not for: Motorhomes without a square rear bumper or rigs already towing a dinghy vehicle.

Underbelly Box – Lippert Underchassis Storage System

Many RVers struggle with limited storage, making the dead space beneath the chassis prime real estate for dirty gear. Mounting a storage box under the frame keeps heavy blocks low to the ground, which helps maintain a low center of gravity. This specialized location keeps filthy leveling blocks completely isolated from your clean living space while utilizing otherwise wasted space.

The Lippert Underchassis Storage System features a heavy-duty plastic bin that slides out smoothly from beneath your RV’s frame rails. The mounting bracket bolts directly to the chassis, providing a secure, out-of-sight storage locker that can hold up to 100 pounds of gear. Its durable polymer construction resists road salt, rocks, and highway debris, keeping your leveling gear safe from road hazards.

Installation requires drilling into your chassis frame, which may require basic mechanical skills and tools. Ground clearance is a critical factor; this system is not recommended for low-riding trailers or off-road rigs that frequently traverse deep ruts. Ensure you measure your frame width and ground clearance before committing to this permanent upgrade.

• Load Capacity: Up to 100 lbs
• Storage Space: Dual bin configurations available
• Installation: Bolt-on design for standard RV frame rails
• Best for: Mid-to-large travel trailers and fifth wheels with ample ground clearance.
• Not for: Low-slung teardrop trailers, off-road overland rigs, or owners uncomfortable with frame-mount installation.

Collapsible Crate – CleverMade Folding Storage Bin

If you transition between heavy travel seasons and long-term stationary stays, permanent rigid storage boxes can get in the way. A collapsible crate provides structured organization when you need to haul dirty blocks, then folds flat when your rig is set up. This flexibility is invaluable in tight camper vans and small travel trailers where space must be managed dynamically.

The CleverMade Folding Storage Bin offers the structural rigidity of a solid plastic crate with the space-saving benefits of a collapsible bag. Made from high-density polypropylene, it features integrated wire rims that prevent the walls from bowing under the weight of heavy rubber chocks. When empty, it collapses down to a mere two inches in height, slipping easily under a mattress or behind a seat.

The open, slatted wall design provides excellent ventilation to dry out damp blocks, but it will not contain liquid runoff or fine dirt. You must place a trash bag or mat beneath the crate if you are storing dripping wet gear on carpeted or wood-paneled utility bays. Regularly inspect the hinge points, as packed dirt and gravel can jam the folding mechanism if not rinsed out occasionally.

• Capacity: 46 Liters (approx. 12 Gallons)
• Collapsed Height: 2.4 inches
• Material: Heavy-duty PP plastic with steel rims
• Best for: Class B camper vans and small trailers where storage space must be reconfigured constantly.
• Not for: Keeping water and fine sand from leaking onto sensitive cargo area floors.

Spare Tire Bag – Trasharoo Spare Tire Trash Bag

Utilizing your exterior spare tire for storage is a brilliant way to keep mud and road grime outside your RV. Shifting dirty blocks to the rear of your rig ensures that wet clay and sand never cross the threshold of your clean interior storage bays. It also keeps your leveling gear immediately accessible right when you pull into a campsite, saving you from digging through packed basements.

The Trasharoo Spare Tire Trash Bag is a legendary overland accessory built to withstand harsh highway speeds and intense sun exposure. Made from heavy-duty 900-denier canvas with double-stitched buckles, it easily secures to vertical spare tires up to 40 inches in diameter. The bag features built-in drainage grommets at the bottom, allowing dirty water from muddy blocks to drain out naturally during transit.

Because it hangs off the back of your rig, the bag and its contents are exposed to rain, highway dirt, and potential theft. You should avoid storing high-value leveling jacks or electronic leveling systems in an unsecured external bag. Over time, UV rays will fade the canvas, so treating the fabric with a UV-protectant spray annually will prolong its lifespan.

• Material: 900D heavy-duty canvas
• Weight Capacity: Up to 50 lbs
• Compatibility: Fits spare tires from 29″ to 40″
• Best for: Camper vans, overland rigs, and travel trailers with rear-mounted spare tires.
• Not for: Rigs without an externally mounted spare tire or those parking in high-theft urban areas.

Waterproof Cargo Bag – Keeper Waterproof Cargo Bag

When your interior basement storage is packed to capacity, roof racks and tongue-mounted cargo trays become essential. However, exposing your leveling gear to the elements on an open tray can lead to highway grit clogging up your block interfaces. A heavy-duty, waterproof cargo bag protects your gear from harsh road spray while ensuring no muddy runoff drips down onto your frame or LP tanks.

The Keeper Waterproof Cargo Bag is built like a tank, constructed from heavy-duty rubberized nylon that keeps highway moisture completely out. It features welded seams and a zipper flap with hook-and-loop closures to prevent water from penetrating even during heavy downpours at highway speeds. This flexibility allows you to pack odd-shaped ramps, wood blocks, and wheel chocks into one tight, weather-protected bundle.

This bag is designed to be strapped down to a rack, meaning you will need a roof rack, tongue tray, or cargo carrier to mount it safely. Because the material is completely non-breathable, putting wet blocks inside will trap moisture and create a humid microclimate. Ensure you dry your blocks at the next stop to prevent mold from growing inside the sealed bag.

• Capacity: 15 cubic feet
• Material: Waterproof rubberized nylon with welded seams
• Attachment: Includes heavy-duty tie-down straps
• Best for: RVers utilizing roof racks or open bumper trays who need total weather protection.
• Not for: Quick-access storage, as unzipping and unstrapping the bag takes several minutes.

Weatherproof Bin – Iris USA WeatherPro Storage Box

Standard plastic storage bins often let in fine road dust and moisture through their lid seams when stored in semi-exposed RV compartments. A truly weatherproof bin provides a hermetic seal that keeps fine desert dust, insects, and humidity away from your leveling blocks. This clean environment is critical if you store your plastic blocks alongside metal tools or electrical adapters that are prone to rust.

The Iris USA WeatherPro Storage Box stands out due to its durable foam gasket seal embedded within the lid. This heavy-duty seal, combined with four secure latches, creates an airtight barrier against dust, moisture, and pests. The clear plastic design allows you to quickly audit your inventory of blocks and chocks without having to unlatch the box.

The clear polycarbonate plastic can become brittle if exposed to direct, continuous UV sunlight for months on end. This bin is best utilized inside your RV’s pass-through storage bay, under-bed storage, or inside a truck bed cover rather than mounted externally on a bumper. Make sure your leveling blocks are completely dry before clamping down the four latches, as the airtight seal will trap any internal moisture indefinitely.

• Capacity: 46.5 Quarts
• Seal Type: Heavy-duty foam gasket with 4 multi-buckle latches
• Material: BPA-free clear polypropylene
• Best for: Dust-heavy environments like the Southwest, and protecting metal leveling jacks from rust.
• Not for: Direct, long-term exterior mounting due to UV degradation.

Ladder Utility Rack – Camco RV Ladder Mount Carrier

If your RV lacks a rear bumper or spare tire, your rear utility ladder is an excellent alternative mounting point for heavy, dirty gear. Utilizing the vertical space on the back of your coach keeps muddy blocks outside the living quarters while keeping them easily reachable. This method utilizes existing structural points on your RV, saving you from drilling new holes or installing heavy bumper frames.

The Camco RV Ladder Mount Carrier is made of lightweight, rust-resistant aluminum and mounts securely to standard 1-inch RV ladder rungs. It features a simple hook-and-loop strap system designed to hold bulky items like chairs, leveling ramps, or utility bags tightly against the ladder. By pairing this rack with a heavy-duty mesh bag, you create a self-draining, exterior storage station that is perfect for muddy blocks.

RV ladders have strict weight limits, typically maxing out at 200 to 250 pounds total, which includes the weight of a person climbing. You must ensure that the combined weight of your leveling blocks and the rack does not overload the ladder mounts during transit. Always secure your blocks with secondary ratcheting straps to prevent them from bouncing loose on rough roads and creating a highway hazard.

• Material: Rust-resistant aluminum with steel hardware
• Weight Capacity: Up to 50 lbs
• Compatibility: Fits standard 1″ diameter RV exterior ladders
• Best for: Class A, B, or C motorhomes with rear exterior ladders and limited basement storage.
• Not for: Heavy, solid rubber chocks or wooden blocks that exceed the safe weight capacity of your ladder.

Sliding Cargo Tray – MORryde Sliding Storage Tray

Reaching into the deep, dark corners of a pass-through storage compartment to grab heavy, dirty leveling blocks can strain your back and mess up your clothes. A sliding cargo tray brings your gear out to you, turning a cramped crawl space into an easily accessible utility drawer. This setup makes it incredibly simple to grab your blocks, set up camp, and slide the messy gear back into its designated spot.

The MORryde Sliding Storage Tray is built with heavy-duty steel and smooth ball-bearing drawer slides that glide effortlessly even when fully loaded. It features a rugged powder-coated finish that resists scratches from abrasive plastic blocks and dirt. The tray extends up to 60% of its length, allowing you to access items buried deep in the center of your pass-through bay without bending over.

This sliding tray requires permanent installation, which involves bolting the steel frame directly to your RV’s compartment floor. The tray itself adds significant weight to your rig and consumes a few inches of vertical storage height. You should combine this tray with a plastic liner or low-profile tote to catch any dirt and mud that shakes off your blocks during travel.

• Weight Capacity: Up to 800 lbs (depending on size)
• Material: Powder-coated steel with ball-bearing slides
• Extension: 60% physical slide-out extension
• Best for: Large fifth wheels and Class A motorhomes with deep pass-through storage bays.
• Not for: Small camper vans or lightweight trailers where every pound of cargo capacity must be guarded.

How to Clean and Prep Dirty RV Blocks Before Storing

Storing dirty leveling gear without a quick cleanup is a recipe for long-term headaches and damaged equipment. Fine sand and grit act like sandpaper, wearing down the interlocking teeth of your plastic blocks over time and compromising their structural stability. A simple three-minute cleaning routine before packing up will dramatically extend the lifespan of your gear and keep your storage bays clean.

Before lifting your blocks out of the dirt, give them a firm tap against a hard surface, like a tree trunk or tire, to dislodge large clumps of mud and gravel. Keep a dedicated, stiff-bristled utility brush and a spray bottle of water in your wet bay for a quick scrub down. Brushing off the honeycomb cavities of your plastic blocks prevents clay and pests from hitchhiking to your next destination.

If you are forced to pack up in a torrential downpour, place the wet blocks in a self-draining container like a mesh bag or open crate for the drive. Once you arrive at your next campsite or a dry, sunny spot, spread the blocks out on the ground to dry completely in the sun. This step is crucial to prevent stagnant water from breeding odor-causing bacteria and mold inside your storage compartments.

Periodically inspect your blocks for stress fractures, deep gouges, or UV degradation while cleaning them. Plastic blocks exposed to intense sunlight will eventually become brittle and crack under the weight of your rig. Catching these structural failures during a routine cleaning prevents a dangerous block collapse the next time you are leveling your RV on uneven terrain.

Managing dirty leveling gear is an unavoidable part of the RV lifestyle, but it does not have to ruin your storage compartments or sanity. By choosing a storage solution tailored to your rig’s layout and committing to a quick cleaning routine, you keep mud outside and your setup process efficient. Invest in the right gear today, and enjoy a cleaner, more organized mobile home on all your future road adventures.
