Best Metal Truck Tool Box for Beds, Trailers and Underbodies

#1 · Best Overall

1. VEVOR Truck Bed Box

• Dimensions: 39"L x 13"W x 10"H
• Material Type: Aluminum
• Capacity: 83 liters

Best for: Corrosion-conscious pickup storage.

Why it ranks #1: Its 39-by-13-by-10-inch aluminum body offers 83 liters of capacity, a 330-pound maximum weight recommendation and two included keys.

A 39-by-13-by-10-inch aluminum chest pairs a diamond-tread surface with a double-sided power coating, giving pickup and trailer owners a corrosion-resistant place to organize tools. Its 83-liter capacity offers room for bulk storage, while the included side handle and two keys support everyday handling and secured access.

The aluminum construction keeps the 17.4-pound box lighter than a steel chest, while the diamond tread and double-sided coating are specified to resist wear, rust, and corrosion. At 39 inches long and 13 inches wide, it provides a defined storage footprint for a truck bed, RV, or trailer; the 10-inch height and 83-liter capacity allow bulkier gear to share space with tools. The two included keys support locking the chest when contents are left stored.

Skip it if you need an underbody box with a sealing strip; VEVOR's 36×17×18-inch underbody model lists one.

Pickup, RV, and trailer owners wanting a lockable aluminum chest for general gear can make use of its 83-liter capacity. Check that its 39-by-13-inch footprint and 10-inch height suit the intended storage area.

#2 · Slim Crossover

2. Northern Tool Crossover Box

• Dimensions: 69"L x 13"W x 12"H
• Material Type: Aluminum
• Capacity: 677 cubic in

Best for: Slim crossover truck storage.

Why it ranks #2: The 69-by-13-by-12-inch aluminum crossover design has a one-piece body, reinforced lid brace and one-hand gas-strut feature.

A slim 69-inch aluminum body gives this crossover box a long, narrow storage profile for truck owners with limited depth behind the cab. Its one-piece construction, reinforced lid brace, and self-adjusting strikers support structural strength and secure closure, while a gas strut enables one-hand operation.

The 69-by-13-by-12-inch dimensions create a slim footprint across the truck bed, and the stated 677-cubic-inch capacity provides a defined amount of storage without a deep box. Its one-piece aluminum body has 0.045-inch walls, while a reinforced lid brace adds strength. Self-adjusting strikers support secure closure, and the one-hand-operated premium gas strut helps when opening the lid while keeping the other hand free for tools or equipment.

Skip it if you need substantially more storage volume; KING CHAO FOO's 36-inch box lists a 35-gallon capacity.

Truck owners needing a slim crossover box and convenient one-hand lid operation may appreciate this aluminum model. Its 677-cubic-inch capacity is a boundary to consider if your regular load includes bulky equipment.

#3 · Best Tongue Box

3. Gooeap Steel Tongue Box

• Dimensions: 35"L x 12"W x 12"H
• Material Type: Alloy Steel
• Capacity: 5040 cubic in

Best for: Lockable trailer-tongue storage.

Why it ranks #3: This 35-by-12-by-12-inch powder-coated alloy-steel box is designed for trailer-tongue storage and includes a lock and two keys.

A fold-up door with an overhanging lip gives this 35-inch steel tongue box full access while helping resist water entry. Its powder-coated black steel body and built-in lock suit owners who want enclosed tool storage on a trailer, with two keys included for locking access.

The 35-by-12-by-12-inch dimensions define a compact rectangular footprint for trailer-tongue or vehicle storage, and the listed 5,040-cubic-inch capacity gives tools and equipment a dedicated space. A fold-up door opens the box fully, making it easier to reach items stored inside than a narrow opening would. The overhanging lip is specified to resist water getting in, while the built-in lock and two keys let owners secure stored contents.

Skip it if you need a larger 35-gallon tongue box; KING CHAO FOO's 36-inch model lists that capacity.

Trailer owners seeking a lockable steel box with an accessible fold-up door may value its defined 35-by-12-by-12-inch footprint. Its stated capacity is 5,040 cubic inches, so consider whether that space suits the tools and equipment you carry.

#4 · Compact Steel

4. KING CHAO FOO 30-Inch Box

• Dimensions: 30"L x 16"W x 14"H
• Material Type: Metal

Best for: Compact steel utility storage.

Why it ranks #4: The 30-by-16-by-14-inch metal box offers a smaller listed length than larger alternatives and is described for truck, pickup, RV and trailer use.

At 30 inches long, this powder-coated steel box offers a shorter storage footprint for truck, pickup, RV, and trailer owners. Its corrosion-resistant finish and reinforced locking latch address weather exposure and security, while side handles support handling the box when its position or contents need attention.

The 30-by-16-by-14-inch dimensions give this metal chest a more compact length than larger truck boxes, while its 16-inch width and 14-inch height provide a substantial enclosure for tools and utility gear. The powder-coated finish is specified to resist rust and corrosion, supporting use in exposed work settings. A heavy-duty locking mechanism with a reinforced steel latch helps secure stored contents, and the listed side handles make it easier to grip the box during handling.

Skip it if you carry long tools and need more length; Jojoka's steel truck box measures 54 inches long.

This suits owners seeking a steel utility box for a truck, pickup, RV, or trailer where a 30-inch length works. Account for its 16-inch width and 14-inch height when deciding where the box will sit.

• Dimensions: 25.6"L x 11"W x 13.6"H
• Material Type: Aluminum
• Capacity: 2.5 cubic feet

Best for: Lightweight ATV and UTV storage.

Why it ranks #5: This aluminum box weighs 4.51 kilograms and lists 2.5 cubic feet of capacity, with a seal-ring design and a 25-pound maximum recommendation.

At 4.51 kilograms, this aluminum box emphasizes lightweight storage for trucks, trailers, garages, and domestic use. A seal ring is specified to help protect the interior from rain and outside factors, while the 2.5-cubic-foot capacity provides a defined space for tools without adding a heavy steel enclosure.

The aluminum body and 4.51-kilogram listed weight can help limit added load on a truck, trailer, or tractor. A seal ring is intended to protect the interior from rain and other external factors, useful when stored tools may encounter weather. The 2.5-cubic-foot capacity gives owners a clear measure of available storage, while the 25-pound maximum weight recommendation sets a firm boundary for loading. Its 5-bar tread pattern strengthens the aluminum surface.

Skip it if you need to carry more than 25 pounds; VEVOR's 39-inch aluminum chest lists a 330-pound maximum.

ATV, UTV, truck, or trailer owners prioritizing lightweight, weather-conscious storage for a limited tool load may find this suitable. Keep its 25-pound maximum recommendation in mind when deciding what to store.

#6

6. Jojoka Steel Bed Box

• Dimensions: 54"L x 16"W x 14"H
• Material Type: Alloy Steel

Best for: Organized long-tool truck storage.

Why it ranks #6: The 54-by-16-by-14-inch alloy-steel box has an 80.5-pound listed weight, multiple compartments and a grooved double lid.

A 54-inch-long steel enclosure with multiple compartments gives this truck box room to organize hand tools and accessories separately. Its grooved double lid supports quick access and added security, while an ergonomic side handle makes the 80.5-pound box portable for truck, RV, or trailer use.

The 54-by-16-by-14-inch dimensions provide a long storage area for tools, and the multiple compartments help separate hand tools and accessories for easier retrieval. Its grooved double lid is described as supporting security and quick access, reducing the need to search through one undivided space. Alloy steel and an impact-resistant feature suit demanding storage conditions, while the ergonomic side handle aids transport; the listed 80.5-pound weight is relevant when planning movement.

Skip it if you need a lighter aluminum chest; VEVOR's 39-inch box weighs 17.4 pounds.

This suits owners with longer tools or assorted accessories who want compartmentalized steel storage in a truck, RV, or trailer. Plan around its 80.5-pound weight and 54-by-16-by-14-inch dimensions when handling and allocating space.

#7

7. EliteEdge Steel Box

• Dimensions: 20"L x 12"W x 9.6"H
• Material Type: Alloy Steel

Best for: Compact lockable steel storage.

Why it ranks #7: Its 20-by-12-by-9.6-inch alloy-steel body is the smallest listed footprint here and includes a dustproof feature.

A 20-by-12-by-9.6-inch steel enclosure offers a compact footprint for keeping tools in a dedicated truck-bed storage space. Its dustproof feature addresses protection from dust, while the listed lockable special feature gives buyers seeking secured storage a reason to consider this small-format box.

The 20-inch length and 9.6-inch height make this a compact choice where a larger chest would occupy too much room; the 12-inch width defines the remaining footprint. Alloy steel gives the enclosure a metal construction, and its dustproof feature is relevant for tools stored in exposed vehicle settings. The lockable listing points to secured access, though the supplied specifications do not state a capacity or describe the locking hardware, so buyers should base selection on its stated dimensions and features.

Skip it if you need a stated large capacity; Gooeap's 35-inch steel box lists 5,040 cubic inches.

This fits buyers seeking a compact steel box with dustproof and lockable features for a limited storage footprint. Its 20-by-12-by-9.6-inch size is the clearest basis for judging whether it suits your tools.

8. Buyers Products Underbody Box

• Dimensions: 36"L x 18"W x 18"H
• Material Type: Alloy Steel
• Capacity: 3401.64 cubic in

Best for: Heavy-duty underbody work-truck storage.

Why it ranks #8: The 36-by-18-by-18-inch underbody box uses 14-gauge steel and a locking compression latch, but its underbody design limits general bed use.

A 14-gauge steel body and stainless steel compression latch make this 36-by-18-by-18-inch box a substantial underbody storage option for work trucks, flatbeds, and trailers. The recessed drop door pulls against a gasket, helping protect contents from weather and reduce rattling during travel.

The 14-gauge steel construction provides a heavy-duty enclosure for tools, parts, and supplies, while the corrosion-resistant black powder coat supports weather-exposed work applications. A stainless steel locking T-handle compression latch pulls the recessed drop door against its gasket, helping secure contents and reduce rattling as the vehicle travels. Its continuous hinge and 36-by-18-by-18-inch dimensions suit underbody or trailer storage, and the stated 3,401.64-cubic-inch capacity sets expectations for available space.

Skip it if you need a lighter underbody box; VEVOR's 36-inch aluminum model weighs 28.4 pounds.

Work-truck, flatbed, and trailer owners needing lockable underbody storage for tools and supplies may value its steel construction and gasketed door. Plan for the 76-pound weight and confirm the 36-by-18-by-18-inch space is available.

#9

9. VEVOR Underbody Box

• Dimensions: 36"L x 17"W x 18"H
• Material Type: Aluminum
• Capacity: 88 lb

Best for: Sealed underbody equipment storage.

Why it ranks #9: This 36-by-17-by-18-inch aluminum box includes two keys and a rubber sealing strip, but it is intended for underbody or similar mounting.

A rubber sealing strip closes against the lid to help keep water and outside elements from stored gear in this 36-by-17-by-18-inch aluminum underbody box. Its lockable T-handle and two keys add controlled access, while the mounting options include truck or trailer undersides, camper backs, and pickup racks.

The 36-by-17-by-18-inch enclosure is sized for maintenance tools or camping equipment, and its stated 88-pound maximum weight recommendation sets a clear loading boundary. A rubber sealing strip helps keep water and external factors out when closed, making it a practical choice for exposed vehicle storage. The T-handle latch and included keys provide lockable access, while the listed installation options—under trucks or trailers, on a camper back, or a pickup rack—offer several placement possibilities.

Skip it if you need a higher stated load limit; VEVOR's 39-inch aluminum truck-bed chest lists a 330-pound maximum.

Truck, trailer, van, or camper owners needing sealed, lockable storage can consider this underbody-style aluminum box. Its 88-pound maximum weight recommendation and 36-by-17-by-18-inch dimensions should guide loading and placement.

#10

10. KING CHAO FOO Yellow Box

• Dimensions: 36"L x 15"W x 15"H
• Material Type: Metal
• Capacity: 35 gallons

Best for: Large-capacity trailer storage.

Why it ranks #10: The 36-by-15-by-15-inch metal box offers 35 gallons and dustproof construction, but its listed dimensions and tongue-box style suit a narrower fit.

A stated 35-gallon capacity gives this 36-inch powder-coated metal box room for substantial tool or equipment storage on a truck, pickup, RV, or trailer. Its yellow finish, locking tongue, and side handles combine secure access with practical handling for owners who need a larger storage chest.

The 36-by-15-by-15-inch dimensions provide a sizable enclosure, and the stated 35-gallon capacity can accommodate more than a small hand-tool assortment. Its powder-coated finish is described as rust- and corrosion-resistant, a useful property for storage exposed to tough weather or job-site conditions. A reinforced steel latch and locking mechanism secure the contents, while side handles provide grip when moving the box; its dustproof feature supports keeping stored items protected from dust.

Skip it if you need a shallow low-profile crossover chest; Northern Tool's 69-inch slim aluminum box has a 12-inch width.

Choose this for truck, pickup, RV, or trailer storage when a 35-gallon capacity and locking access matter. Its 36-by-15-by-15-inch dimensions and yellow finish are important considerations for the available space and setup.
