MTM MGC – The Mule Mobile Gear Crate, Water-Resistant, Stackable Storage for Hunting and Outdoor Gear, Army Green
The MTM MGC stands out for its large 81-quart capacity and multiple compartments, making it ideal for organizing diverse outdoor gear. Its water-resistant seal provides better protection against rain than the Keter Marvel Plus, which relies on weather-resistant resin but isn’t specifically water-tight. Unlike the 50 Gallon Mobile Chest, the MGC offers more customization with its removable divider, though it’s heavier when fully loaded, which could be a challenge for those needing frequent transport. Its wheels and handles make moving bulky gear easier, but the size may be cumbersome in tight spaces. This pick is best for outdoor enthusiasts who prioritize organization and protection without needing full submersion capability.
Pros:- Large 81-quart capacity with multiple compartments
- Water-resistant seal helps keep gear dry
- Includes wheels and handles for easy transport
- Removable divider for customizable organization
Cons:- Not fully submersible, limited water protection
- Heavy when fully loaded
- Larger size may be cumbersome for small storage needs
Best for: Hunting, camping, or outdoor gear users needing organized, portable storage with water resistance
Not ideal for: Small space owners or those seeking fully submersible waterproof storage
- Capacity:81 quarts
- Dimensions:15.1″L x 11.8″W x 44.02″H
- Weight:14 pounds
- Material:Polypropylene (PP)
- Closure Type:Snap
- Water Resistance:Water-resistant (not submersible)
Bottom line: This is a strong choice for outdoor users needing durable, organized, and portable storage that resists rain but isn’t meant for full immersion.
50 Gallon Mobile Chest
The 50 Gallon Mobile Chest offers substantial storage with its impressive 50-gallon capacity, making it suitable for storing bulky tools or equipment. Its durable high-density foam construction surpasses typical plastic bins in impact resistance, similar to the Plano Sportsman’s Trunk, but with the advantage of a spacious, single-structure design. While it excels in capacity and mobility with rubber-coated wheels and a soft grip handle, it lacks internal compartments for organized storage, unlike the MTM MGC. The absence of a lockable lid could be a concern for security, especially in outdoor settings. This model is best for users who need straightforward, high-capacity storage that’s easy to move around, without fussing over multiple compartments.
Pros:- Large 50-gallon capacity for bulky items
- Durable high-density foam construction
- Easy to maneuver with rubber wheels and soft grip handle
- Versatile work surface with saw grooves
Cons:- Limited internal organization options
- Heavy when fully loaded
- No lockable lid for added security
Best for: DIYers, tradespeople, or outdoor enthusiasts needing large, mobile storage for bulky gear
Not ideal for: Users needing detailed organization or secure lockable compartments
- Capacity:50 gallons
- Dimensions:21.5 x 14.5 x 17.5 inches
- Material:High-density structural foam
- Maximum Weight:107 kg
- Color:Black
- Style:Modern rectangular
Bottom line: This is an excellent choice for users requiring large, portable storage for heavy or bulky outdoor gear without fussing over compartments.
Keter Marvel Plus 71 Gallon Resin Outdoor Storage Box
The Keter Marvel Plus shines in outdoor settings with its weather-resistant resin construction and a capacity of 71 gallons, making it suitable for storing outdoor accessories. Its dual function as a bench with a 485 lb weight capacity offers added value over typical storage trunks like the Plano Sportsman’s Trunk. However, its interior height may restrict larger items, and the resin finish could fade over time if exposed to harsh sunlight, unlike the more durable plastics used in the Plano Sportsman’s Trunk. Assembly is required, which can be a minor inconvenience. This pick is best for small patios or balconies where a combination of seating and storage is needed, and weather resistance is a priority.
Pros:- Weather-resistant resin construction
- Provides additional seating with a sturdy bench
- Ample 71-gallon capacity for outdoor gear
- Compact size for small outdoor areas
Cons:- Limited interior height for large items
- Potential fade over time in sunlight
- Requires assembly
Best for: Small outdoor spaces needing a weatherproof, multi-use storage solution
Not ideal for: Those seeking high internal height for large gear or full submersion protection
- Dimensions:45.9″ W x 17.4″ D x 22.2″ H
- Interior Dimensions:44.6″ W x 15.6″ D x 20″ H
- Capacity:71 gallons
- Weight Capacity:485 lbs
Bottom line: Ideal for outdoor spaces requiring weatherproof storage combined with seating, but not suited for storing very tall or bulky items.
Plano Storage Trunk – 108 Quart with Wheels (1819) – Hunter Green
The Plano Storage Trunk offers a generous 108-quart capacity combined with built-in wheels, making it a standout for secure transport of outdoor or sports gear. Its lockable design and airline approval add security benefits that surpass the 50 Gallon Mobile Chest. While its size and weight can be a drawback for frequent lifting, the molded stacking grooves and recessed handles facilitate stacking and handling. Compared to the larger, less secure MTM MGC, this trunk emphasizes security and ease of transport. It’s best for users who need a large, lockable container for frequent movement, especially in outdoor or travel settings, but it might be less appealing for those seeking maximum capacity in a single container.
Pros:- Easy to transport with wheels and recessed handles
- Lockable for security and airline approved
- Stackable design saves space
- Molded grooves for secure stacking
Cons:- Heavy when fully loaded
- Limited color options
- Size may be cumbersome for small storage needs
Best for: Travelers, outdoor event organizers, or those needing secure, lockable large storage
Not ideal for: People looking for lightweight options or with very limited storage space
- Capacity:108 quarts
- Color:Hunter Green
- Wheels:Yes
- Lockable:Yes
- Airline Approved:Yes
Bottom line: Best suited for users needing a high-capacity, lockable, portable storage solution that travels well, though it sacrifices some lightweight convenience.
Plano Sportsman’s Storage Trunk
The Plano Sportsman’s Storage Trunk is built with impact-resistant plastic, offering durable outdoor protection in a mid-sized 56-quart capacity. Its weather-resistant, lockable lid and sturdy tie-down points make it suitable for outdoor adventures or heavy-use storage needs. Compared to the MTM MGC, it emphasizes impact resistance over water resistance, making it less ideal in heavy rain, but more resilient against impacts and rough handling. Its bulk can be a concern for smaller storage spaces, and it lacks the larger capacity of the 50 Gallon Mobile Chest. This product is best for outdoor enthusiasts seeking impact-proof, weather-resistant storage that can be secured during transport but don’t need extensive capacity.
Pros:- Impact-resistant, durable construction
- Weather-resistant and lockable for security
- Sturdy tie-down points for stability during transport
- Large interior space for bulky gear
Cons:- Heavy when fully loaded
- Bulky for small storage spaces
- Limited capacity compared to larger trunks
Best for: Outdoor sports, tools, or gear requiring impact resistance and security
Not ideal for: Indoor users or those needing high capacity or flexible organization
- Interior dimensions:26″L x 11.25″W x 11.25″H
- Exterior dimensions:30″L x 14.25″W x 12.75″H
- Color:Charcoal
- Capacity:56 quarts
Bottom line: This is a dependable, impact-resistant storage option for outdoor gear, sacrificing some capacity for durability and security.
Plano Storage Trunk – 56 Quart (2 Pack), Black, 24 x 15 x 13 inches
This set of two Plano 56-quart trunks offers a practical storage solution with a focus on flexibility and stacking ability. Compared to the Rubbermaid ActionPacker, these trunks lack wheels and handles, making them less mobile but more suitable for stationary storage. Their molded grooves enable secure stacking, and the reinforced lids boost durability, which is ideal for organizing household or garage items. However, the absence of handles limits portability, especially when full. These trunks excel in setups where stacking stability and cost-effectiveness matter more than portability. They are best suited for bulk storage in a fixed location rather than frequent transport or outdoor use. While they lack the rugged features of the Rubbermaid ActionPacker, their large capacity and sturdy design deliver significant value for budget-conscious buyers who prioritize organization over mobility.
Pros:- Large 56-quart capacity for versatile storage needs
- Sturdy stacking design with molded grooves for stability
- Lockable attachment points for added security
- Reinforced removable lid enhances durability
Cons:- No handles, making portability difficult when full
- Limited color options restrict aesthetic flexibility
Best for: Homeowners needing large, stackable storage for garage or basement organization
Not ideal for: Outdoor enthusiasts requiring rugged, portable solutions with wheels and impact resistance
- Capacity:56 quarts
- Dimensions:24 x 15 x 13 inches
- Number of Items:2
- Material:Plastic
- Color:Black
- Shape:Rectangular
- Style:Modern
Bottom line: This set is ideal for those who need large, stable storage units that stay stationary and offer good value for bulk organization.
Rubbermaid ActionPacker 35 Gallon Lockable Plastic Storage Bin with Lid and Wheels – Gray and Black
The Rubbermaid ActionPacker stands out for heavy-duty durability, making it well-suited for outdoor storage, camping, or industrial environments. Unlike the Plano trunks, it includes wheels, which significantly ease transportation over uneven terrain, and its impact-resistant, lockable lid offers enhanced security against harsh conditions. Its 35-gallon capacity is smaller but better suited for gear that needs to be moved frequently or stored outdoors. A notable tradeoff is the lack of a lock or bungee cord included, which could be a concern for security. Although it is bulkier than typical household trunks, its rugged design and mobility features justify the higher price and weight. This pick is best for users who demand tough, portable storage to withstand outdoor elements, but it might be overkill for simple indoor storage needs.
Pros:- Heavy-duty, impact-resistant construction for rugged environments
- Water-repellent lid with secure locking mechanism
- Wheels facilitate easy transport over uneven surfaces
- Constructed with recycled materials, supporting sustainability
Cons:- Lock and bungee cord are not included, reducing security options
- Bulkier and heavier than typical storage trunks, less ideal for small spaces
Best for: Outdoor adventurers, campers, or workers needing durable, mobile storage in rough conditions
Not ideal for: Indoor users with limited space or those seeking lightweight, non-industrial storage options
- Capacity:35 Gallons
- Dimensions:35.91″ L x 17.73″ W x 19.49″ H
- Weight:21 Pounds
- Material:Plastic
- Color:Gray and Black
- Features:Lockable, Impact-resistant, Water-repellent lid, Wheels, Recycled content
Bottom line: This container excels for outdoor or industrial storage where durability and mobility are priorities, though it may be too bulky for casual indoor use.
How We Picked
The products in this roundup were selected based on their capacity, weatherproof features, build quality, and user reviews. Priority was given to trunks that offer true waterproofing—meaning they resist water ingress under heavy rain or submersion—and those with durable materials suited for outdoor or heavy-duty use. Portability features, such as wheels and handles, were also considered, alongside value for money. The ranking reflects a balance of these factors, favoring products that offer the best combination of waterproof protection, capacity, and usability for different types of buyers.Factors to Consider When Choosing Waterproof Storage Trunk Large
Choosing a large waterproof storage trunk involves more than just capacity. Considering factors like material durability, waterproofing standards, portability, and security will help you find a model that suits your specific needs. It’s easy to fall for a feature that sounds great but doesn’t hold up in real-world conditions, so understanding these considerations can save you money and frustration.Material and Waterproofing Standards
The quality of the material directly impacts how well a trunk resists water. Look for products made from high-density resin, heavy-duty plastic, or reinforced polymers that can withstand prolonged exposure to moisture. Check for IP (Ingress Protection) ratings or similar standards that quantify waterproofing; a rating of IPX7 or higher indicates protection against immersion. Cheaper options might claim water resistance but often lack true waterproof seals, so verify the construction details carefully.
Capacity and Size
Large trunks come in a range of capacities, from around 50 gallons to over 100 gallons. Think about what you’ll store—if bulky gear or multiple items, opt for higher volume. Keep in mind that bigger trunks can become cumbersome, especially if they lack wheels or handles. Balance capacity with ease of handling, especially if you need to move or transport the unit frequently.
Portability and Ease of Use
Many large trunks come with wheels, handles, or stacking features. If portability is a priority, look for models with durable wheels and ergonomic handles. However, added features can increase weight and complexity. Consider how often you’ll need to move the trunk and whether the added convenience justifies the extra cost or weight—some compact models with wheels perform well for occasional transport, while larger stationary units are better for long-term outdoor storage.
Security Features
Since these trunks often store valuable or sensitive gear, lockability can be important. Many models include built-in locks or provisions for padlocks. Keep in mind that some cheaper trunks might compromise security for waterproofing, so verify if locking mechanisms are robust and weather-resistant. If security is a concern, prioritize models that combine waterproofing with sturdy locking options.
Price and Value
Price ranges widely based on size, material, and features. While premium models offer superior durability and waterproofing, budget options can still provide adequate protection for light or infrequent use. Consider how often and in what environments you’ll use the trunk—spending more on a heavy-duty, weatherproof model makes sense if it’s exposed to harsh conditions regularly. Conversely, if you only need occasional outdoor storage, a less expensive, less feature-rich model might suffice.
Frequently Asked Questions
Will a plastic storage trunk keep my gear completely dry in heavy rain?
Most high-quality plastic trunks with proper seals and latches can keep gear dry during heavy rain, but true waterproofing depends on the design and quality of seals. Look for models with gasketed lids, secure locking mechanisms, and verified waterproof ratings like IPX7. Remember, no container is entirely foolproof if it’s subjected to prolonged submersion or extreme conditions, so choose a trunk that matches your specific environment and storage needs.
Can I use a waterproof storage trunk for marine or boat storage?
Yes, many waterproof trunks are suitable for marine environments, especially those made from marine-grade resin or plastics with sealed lids. However, verify the product specifications for saltwater resistance and corrosion-proof components. Keep in mind, some trunks are designed more for land-based outdoor storage and may not withstand constant exposure to saltwater or prolonged immersion, so check the manufacturer’s recommendations before use on boats or docks.
Are wheeled trunks easier to move around outdoors?
Wheeled trunks can significantly improve mobility, especially when dealing with large, heavy containers. However, wheels can add weight and complexity, and their durability depends on construction quality. For rough terrain, look for models with large, sturdy wheels designed for outdoor use. If you only need to move the trunk occasionally or over smooth surfaces, a wheeled model simplifies handling without adding much complexity.
How do I maintain the waterproof integrity over time?
Regular maintenance includes cleaning the seals and gasket areas to prevent dirt and debris from compromising waterproofing. Lubricating rubber gaskets with silicone spray can keep them pliable and effective. Check for cracks or damage periodically, especially after rough handling or exposure to extreme weather. Proper storage and gentle handling help prolong the lifespan of waterproof seals and overall integrity.
Is a larger capacity always better for outdoor storage?
While a larger capacity provides more storage space, it can also mean increased weight and reduced portability. Larger trunks are ideal when you need to store bulky or numerous items permanently, but they may be cumbersome to move or require more space. Consider your specific storage environment—if you need frequent access or transport, a slightly smaller but easier-to-handle model might be more practical.
Conclusion
For those needing the best overall waterproof large trunk, the Keter Marvel Plus 71 Gallon Resin Storage Box combines weather resistance with ample capacity and ease of use. Budget-conscious buyers or casual outdoor users will appreciate the Plano Storage Trunk – 108 Quart with Wheels for its affordability and mobility. For heavy-duty, outdoor, or marine environments, the MTM MGC – The Mule offers unmatched durability. Beginners or occasional users should consider smaller, simpler models to avoid unnecessary complexity, while professionals or those with harsh outdoor conditions should prioritize premium, sealed, and lockable options for long-term peace of mind.
