8 Best Gear Tunnel Storage Solutions for Class B Motorhomes

Packing a Class B motorhome gear tunnel, often called the “garage,” is a high-stakes game of real estate where every cubic inch counts. Without a strategic organization system, this rear storage area quickly devolves into a chaotic pile of tangled cords, dirty camp chairs, and inaccessible gear. Choosing the right storage solutions transforms this cramped void into an efficient, stress-free hub that keeps your outdoor essentials organized and ready at a moment’s notice.

Optimizing Class B Motorhome Gear Tunnel Storage

Class B motorhomes offer incredible mobility, but their compact footprints mean the rear gear tunnel—often located under a platform bed—must work double duty. This space needs to house everything from bulky utility hoses and leveling blocks to outdoor recreational gear and tools. Without a dedicated system, retrieving a single item from the back of the tunnel requires unloading the entire space onto the dirt.

True optimization relies on the principle of accessibility; if you cannot reach an item within thirty seconds, its storage location is failing you. By dividing the garage into distinct zones based on frequency of use, weight distribution, and dirty-versus-clean categories, you protect your gear and your sanity. The goal is to create a modular layout where every component secures tightly to prevent shifting during transit on rough backcountry roads.

Cargo Slide – MorRyde Sliding Cargo Tray

Deep gear tunnels are notorious back-breakers, forcing you to crawl into a dark, cramped space just to reach items stored near the front. A heavy-duty cargo slide solves this by turning the entire floor of your van garage into a giant, roll-out drawer. This category of gear is the foundation of any high-end garage build, ensuring that nothing gets lost in the inaccessible depths of your layout.

The MorRyde Sliding Cargo Tray stands out because of its rugged steel construction and smooth ball-bearing slides that operate flawlessly even under heavy loads. It features a robust locking mechanism that prevents the tray from rolling out while parked on an incline. The durable powder-coated finish shrugs off scrapes from metal toolboxes and muddy hiking boots alike.

• Weight Capacity: 800 lbs (fully extended)
• Extension: 80% or 100% stroke options
• Best For: Heavy toolboxes, portable generators, auxiliary water jugs, and bulky storage bins
• Materials: Durable, powder-coated steel tray with ball-bearing slide assemblies

Before purchasing, account for the physical footprint of the unit. The tray and its mounting brackets consume roughly three to four inches of vertical clearance, which can be a dealbreaker if your mountain bikes are already tight against the underside of your bed. Installation requires bolting directly through your van’s metal floor, meaning you must carefully map out what lies beneath—such as grey tanks or wiring harnesses—before drilling.

This slide is ideal for travelers who transport heavy, dense items and want effortless access. It is not the right fit for minimalists on a strict payload budget, as the steel assembly adds significant dead weight to your rear axle.

Molle Panel – Flarespace Rear Door Molle Panel

Rear doors are often overlooked real estate, yet they offer the perfect canvas for organizing frequently used, hand-sized gear. Molle panels utilize military-grade grid systems to let you strap, clip, or bolt items directly to the door face, keeping them off the floor and instantly visible. This setup keeps emergency tools, flashlights, and first-aid kits within arm’s reach the moment you swing the doors open.

The Flarespace Rear Door Molle Panel is the premier choice for Class B owners due to its precision, vehicle-specific fit and lightweight construction. Unlike generic plastic grids, this panel will not bow or rattle when driving over washboard dirt roads. The black powder coat matches factory interiors and resists rust from exposure to rain and condensation when the doors are open.

• Material: 1/8-inch CNC-cut heavy-duty aluminum
• Fitment: Sprinter, Transit, and Promaster specific door layouts
• Compatible Gear: Quick Fist clamps, Molle pouches, recovery gear, axe/shovel mounts
• Finish: Textured black powder coat

Keep in mind that mounting heavy items like axes or heavy recovery boards to a door panel puts extra stress on your van’s door hinges over time. You will need to purchase high-quality Molle-compatible straps or Quick Fist clamps separately to mount your gear to the panel. Ensure your door insulation and inner panels are finished in a way that allows the mounting hardware to thread securely into the metal frame.

This panel is a must-have for overlanders and off-grid campers who need rapid access to safety gear, tire deflators, and hand tools. It is less suitable for those who prefer to keep all their gear completely hidden from sight when the rear doors are open for ventilation.

Storage Bin – Front Runner Wolf Pack Pro

Loose gear is the enemy of a peaceful van interior, creating noise on the road and sliding into hard-to-reach corners. Heavy-duty utility bins provide a modular, stackable solution to group like items together—such as electrical adapters in one box and plumbing fittings in another. They turn a chaotic pile of small parts into a neat, easily movable library of gear.

The Front Runner Wolf Pack Pro is the gold standard for rugged cargo storage because of its impact-resistant plastic construction and secure latch system. These bins are dustproof and water-resistant, meaning you can set them outside in the dirt or rain at camp without worrying about dampness or bugs invading your gear. Their nested lid design allows multiple bins to stack securely on top of each other without slipping.

• External Dimensions: 20.1″ L x 15.8″ W x 9.1″ H
• Internal Volume: 37 Liters
• Material: Black high-density polyethylene (HDPE) plastic
• Key Feature: Stackable lid design with integrated heavy-duty plastic latches and gasket seal

While these bins are incredibly tough, their rigid plastic latches require a firm, dual-handed press to snap shut, which can be tough in cold weather. Because their outer dimensions are fixed, you must measure your gear tunnel height carefully to ensure you can stack two or three units high beneath your bed platform.

These bins are perfect for organized travelers who want a dustproof, insect-proof storage system that can easily transition from the inside of the van to the dirt outside. They are not ideal for those looking to store oddly shaped, extra-long items like camp chairs or rolled-up mats.

Cargo Net – Gladiator Heavy Duty Cargo Net

Even when items are organized, a sudden stop can turn loose sleeping bags, pillows, or camp chairs into dangerous projectiles that slam against your rear doors or bed frame. A high-quality cargo net acts as a flexible partition wall, holding bulkier, lightweight gear securely in place against the back of your garage. It provides passive safety and peace of mind during steep descents or sudden highway braking maneuvers.

The Gladiator Heavy Duty Cargo Net stands out because of its weatherproof, rip-stop mesh construction, which prevents smaller items from slipping through like they would with traditional elastic bungee nets. It features multiple integrated attachment points and heavy-duty hardware that can handle serious shifting forces without snapping. The net is rated to hold hundreds of pounds of cargo, ensuring even your heaviest gear bags stay contained.

• Material: Heavy-duty, rip-stop mesh and reinforced webbing straps
• Hardware: Includes four attachment hardware straps and a convenient storage bag
• Load Rating: High-strength rating for commercial-grade containment
• Best Uses: Securing camp chairs, rolled tents, sleep setups, and loose duffel bags

To make the most of this net, you must have solid anchor points installed along the walls or floor of your gear tunnel, such as L-track or heavy-duty D-rings. Adjusting the straps to the correct tension can take a few minutes, making it slightly tedious if you need to access the secured gear multiple times a day.

This cargo net is an excellent choice for solo travelers or families who pack their gear tunnels to the brim with soft goods and bulky camp gear. It is not necessary for those whose garages are already fully outfitted with built-in cabinetry or drawer systems.

L-Track Kit – US Cargo Control L-Track Rail Kit

A fixed tie-down point is only useful if it happens to be exactly where your gear needs it, which is rarely the case in a multi-sport van build. L-Track (logistic track) provides a continuous, adjustable rail system that allows you to move, add, or remove tie-down points in seconds. This flexibility is essential for van lifers whose gear layouts change with the seasons.

The US Cargo Control L-Track Rail Kit is the industry favorite due to its heavy-duty construction, which offers incredible tensile strength without adding excess weight. The pre-drilled countersunk holes make flush installation straightforward, and the kit includes a variety of single-stud fittings that click smoothly into the tracks. This allows you to secure anything from a heavy mountain bike to a small cooler with equal confidence.

• Material: Aircraft-grade 6061-T6 aluminum
• Track Lengths: Four 4-foot rails per standard kit
• Fittings: Includes single-stud rings and threaded fittings
• Installation: Requires countersunk mechanical fasteners

Installing L-Track correctly requires a solid structural backing, such as the van’s steel ribs or a thick plywood subfloor; simply screwing it into thin wall paneling will result in failure under load. You will also need to invest in a collection of compatible L-track accessories, such as ring studs, threaded studs, or specialized bike mounts, to fully utilize the system.

This kit is perfect for DIY builders and active outdoor enthusiasts who carry a rotating inventory of gear like bikes, boards, and gear boxes. It is overkill for casual RVers who travel with the exact same minimal setup on every trip.

Gear Bag – Patagonia Black Hole Duffel 100L

Hard plastic bins are excellent for stacking, but their rigid shapes leave awkward, unused gaps in the irregular curves of a van’s rear walls. Heavy-duty gear bags fill these voids perfectly, compressing down to fit into tight spaces while protecting soft goods like winter coats, wetsuits, or sleeping bags. They also make it easy to pack up your gear and carry it straight into a hotel room or laundromat.

The Patagonia Black Hole Duffel 100L is the ultimate gear hauler because of its water-resistant construction and highly durable TPU-film laminate. It shrugs off moisture, grease, and dirt from the garage floor, keeping your clean clothes and gear protected inside. The padded, removable backpack straps make it easy to carry heavy loads over long distances when you need to transport gear away from the van.

• Capacity: 100 Liters (6,102 cubic inches)
• Material: 100% recycled body fabric, lining, and webbing with weather-resistant TPU-film laminate
• Features: Padded, removable shoulder straps, reinforced haul handles, and internal mesh pockets
• Weight: 3 lbs 9.7 oz (empty)

Because this is a soft-sided bag, it provides zero crush protection for delicate electronics or fragile camp kitchen gear. When fully packed to its 100-liter capacity, it becomes quite heavy and bulky, so you must plan a dedicated, easily accessible spot in your tunnel where it won’t block other essential gear.

This bag is ideal for multi-sport athletes, skiers, and long-term travelers who need to pack large volumes of clothing and soft gear into irregular spaces. It is not the right choice for storing heavy, sharp hand tools or greasy recovery equipment that could puncture the fabric over time.

Folding Crate – CleverMade Collapsible Crate

Space is at an absolute premium in a Class B motorhome, meaning you cannot afford to have empty storage containers taking up valuable room when not in use. Folding crates offer a brilliant, temporary storage solution that pops open when you need to transport groceries, firewood, or laundry, and folds flat when you do not. They bridge the gap between permanent organization and day-to-day utility.

The CleverMade Collapsible Crate is the preferred choice because of its sturdy interlocking wall design and comfortable side-grip handles. With its spacious capacity and sturdy weight limit, it handles heavy canned goods or damp firewood without buckling. When collapsed, it shrinks down to less than three inches in height, allowing you to slide it under a mattress or behind a seat out of sight.

• Capacity: 62 Liters (16 gallons)
• Weight Limit: Up to 100 lbs
• Dimensions (Open): 23.5″ L x 15.3″ W x 11.25″ H
• Dimensions (Collapsed): 23.5″ L x 15.3″ W x 2.25″ H

While highly versatile, these crates are made of lightweight plastic hinges that can snap if dropped onto hard surfaces while fully loaded. They are not dustproof or waterproof, so they should not be used for long-term storage of items sensitive to moisture or dust in the gear tunnel.

This crate is perfect for weekend warriors and full-time travelers who need a flexible, temporary hauling solution for groceries, trash, or beach gear. It is not designed for permanent gear mounting or heavy-duty tool storage.

Magnetic Bar – Olsa Tools Magnetic Tool Organizer

Digging through a messy toolbox for a basic screwdriver or wrench is a frustrating waste of time when you are trying to make a quick roadside adjustment. Magnetic organizer bars utilize vertical wall space in your gear tunnel to keep your most frequently used hand tools visible, organized, and ready for action. This setup keeps heavy metal tools out of drawers, reducing the irritating rattles that plague Class B motorhomes on the highway.

The Olsa Tools Magnetic Tool Organizer is a top-tier choice because it uses high-strength magnets encased in a heavy-duty steel frame. This bar has a powerful magnetic pull that securely holds heavy wrenches, pliers, and even small hammers in place through rough driving conditions. The sleek, compact design takes up virtually zero space, allowing you to mount it on the inside of a cabinet door or along a metal wall rib.

• Material: Solid steel backing plate with high-potency neodymium magnetic strips
• Weight Capacity: Holds up to 15 lbs of steel tools per bar
• Length: Available in 12-inch or 18-inch options
• Mounting: Pre-drilled screw holes at each end

Keep in mind that while the magnets are incredibly strong, a massive pothole or off-road washboard can still dislodge heavy tools if they are not positioned with maximum surface contact. You must mount the bar to a solid surface using the included screws, as double-sided tape will quickly fail under the weight of the tools and the vibrations of travel.

This organizer is perfect for hands-on travelers who do their own basic vehicle maintenance and want instant access to their core hand tools. It is not suitable for non-magnetic titanium or plastic tools, nor is it recommended for mounting in areas where passengers might bump into exposed sharp tools.

How to Measure Your Gear Tunnel Before Buying

Measuring a Class B gear tunnel is far more complex than simply pulling a tape measure from the back doors to the front wall. These spaces are rarely perfect rectangles; they are interrupted by wheel wells, freshwater tanks, electrical wheel arches, and heater ducting. To get an accurate assessment, you must measure the minimum clearances—the narrowest point between the wheel wells and the lowest point beneath the bed frame or support struts.

Do not forget to account for the “swing clearance” of your rear doors and any hinges or latch mechanisms that protrude into the doorway opening. A cargo slide may fit perfectly inside the garage but fail to slide out if the rear door hinges block its path by even a quarter of an inch. Always take three measurements for depth, width, and height: one at the floor, one at the midpoint, and one at the highest clearance point.

Finally, consider the dynamic space required for your gear to slide or lift. If you plan to store mountain bikes on a tray, measure the height of the bikes with the front wheels removed, and add at least two inches to account for the thickness of the slide tray and mounting hardware. Mapping these dimensions out on a sheet of graph paper before buying any storage bins or slide-outs will save you costly return shipping fees and hours of frustration.

Maximizing Vertical Space in Narrow Van Garages

The secret to efficient van organization lies in looking up; most people pack their gear tunnels from the floor up and leave the top half of the space completely empty. In a narrow Class B garage, vertical space is your greatest asset. Utilizing wall-mounted tracks, under-bed shelving, and ceiling hooks allows you to suspend lighter items like camp tables, ski poles, and leveling blocks, freeing up valuable floor space for heavier cargo.

Creating a “false floor” or installing a raised platform bed is another highly effective way to double your usable surface area. By placing low-profile storage bins or a sliding tray on the bottom level and a secondary shelf just below the bed platform, you eliminate the need to stack heavy boxes directly on top of each other. This modular vertical structure ensures that every item has its own dedicated slot, preventing the “domino effect” of gear falling over when you retrieve a single item.

For ultra-narrow garages, consider using soft-sided storage pockets or heavy-duty canvas organizers that screw directly into the wall panels. These pockets conform to the shape of whatever you put inside them and lie completely flat when empty, maximizing walkthrough clearance. When organizing vertically, always place the lightest items at the top and the heaviest items on the floor to maintain a low center of gravity for better vehicle handling.

Essential Tips for Securing Heavy Cargo on the Road

Unsecured cargo in a Class B motorhome is not just noisy—it is a significant safety hazard. In a collision or sudden evasive maneuver, a loose 20-pound generator or toolbox can easily break through a lightweight bulkhead and injure passengers in the living area. Every heavy item in your gear tunnel must be mechanically anchored to the vehicle’s chassis or a reinforced subfloor using rated tie-down straps.

When securing heavy gear, ditch the elastic bungee cords in favor of cam straps or high-quality ratchet straps. Bungees stretch under load, allowing cargo to shift and build up momentum before snapping back, which can lead to broken anchor points or damaged gear. Ratchet straps provide positive, unyielding tension that locks heavy items directly to your L-track or D-ring systems, keeping them completely stationary over the roughest terrain.

Weight distribution is equally critical for safety and vehicle performance. Always position your heaviest items—such as toolboxes, water tanks, and recovery gear—as low as possible and forward of the rear axle to maintain optimal balance and traction. Regularly inspect your tie-down points, straps, and buckles for signs of fraying or fatigue, especially before embarking on long road trips or bumpy off-road adventures.

Conclusion

Organizing your Class B gear tunnel requires a thoughtful combination of rugged hardware, smart vertical layouts, and secure tie-downs. By implementing these modular storage solutions, you turn a chaotic clutter zone into an efficient, safe system that saves you time and energy on every adventure. Invest the effort to measure, secure, and organize your garage today, and enjoy a rattle-free, stress-free road trip tomorrow.
