Best Aluminum Storage Box For Trucks: 10 Options Compared

#1 · Best Overall

1. VEVOR 39-Inch Truck Box

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

Best for: Wide pickup-bed tool storage.

Why it ranks #1: A conventional bed chest with 83 liters of capacity, 39 × 13 × 10-inch dimensions, a 330-pound maximum weight recommendation, and two keys.

A 39-by-13-inch footprint gives this VEVOR chest a long, shallow format for organizing tools in a pickup bed, RV, or trailer. Its 83-liter capacity supports bulk storage, while the diamond-tread aluminum surface and widened handle make it easier to move and handle around a vehicle or work area.

The double-sided power-coated aluminum alloy and diamond tread are described as resistant to rust, corrosion, and abrasion, helping the chest hold up to regular use. Its 39-by-13-by-10-inch dimensions provide a long storage area without the height of a deeper box, which can suit longer tools and gear. A widened handle supports carrying, and the lock with two included keys lets owners secure stored items. The listed maximum weight recommendation is 330 pounds.

Skip it if you need to store tall tools upright; the 10-inch box height favors lower-profile gear.

Pickup, RV, and trailer owners organizing bulkier but relatively low-profile gear get a long storage area, a carrying handle, and keyed security. Choose it with the 39-by-13-by-10-inch dimensions in mind, especially if your tools need more vertical room.

#2 · Highest Capacity

2. KING CHAO FOO 39-Inch Box

• Dimensions: 39"L x 15"W x 14"H
• Material: Metal
• Capacity: 35 gallons

Best for: Wide, divided truck-bed storage.

Why it ranks #2: Its listed 39 × 15 × 14-inch size and 35-gallon capacity suit buyers prioritizing volume; it also includes two keys and two trays.

A 39-by-15-by-14-inch body and two trays give the KING CHAO FOO box space for larger gear alongside smaller items. Its listed 35-gallon capacity suits truck, pickup, RV, trailer, garage, or worksite storage, while the side handle and lock with two keys support carrying and securing the contents.

The two trays provide partitioned storage, helping separate small parts from bulkier repair tools rather than leaving everything in one compartment. Its 35-gallon capacity and 39-by-15-by-14-inch dimensions accommodate a substantial load of gear, though the wide footprint calls for enough available space in the vehicle or work area. The box is listed for all-weather use and as dustproof, which supports storing equipment across varied settings. A side handle and two keys are included.

Skip it if you have limited width available; this model measures 15 inches across.

Owners needing separated storage for small items and larger tools across truck, RV, trailer, or garage use can make use of its two trays and 35-gallon capacity. Check that the 39-by-15-by-14-inch footprint suits the available space.

#3 · Compact Bed Chest

3. FORWODE 30-Inch Truck Box

• Dimensions: 30"L x 13"W x 10"H
• Material: Aluminum

Best for: Portable 30-inch truck storage.

Why it ranks #3: The 30 × 13 × 10-inch all-welded aluminum chest has handles on both sides, a lock, and two keys for a standard bed-storage setup.

Two non-slip side handles make this 30-inch FORWODE aluminum box easier to carry between a truck, trailer, and work area. Its 30-by-13-by-10-inch dimensions provide an organized tool-storage footprint, while the all-welded construction, diamond plate, and lock with two keys suit outdoor vehicle use.

All-welded aluminum construction is described as lightweight and anti-corrosion, supporting outdoor use without making the box difficult to transport. The diamond-plate surface adds a durable exterior, while the two side handles provide grip when moving it. A lock and two keys help secure tools or accessories in the 30-by-13-by-10-inch chest. That size offers a moderate storage footprint, but the 10-inch height sets a limit for equipment that needs to stand upright.

Skip it if you need to store tall equipment upright; the 10-inch height favors lower-profile tools and accessories.

Truck and trailer owners who move tools between vehicles and work areas get a portable, lockable aluminum chest with handles on both sides. Its 30-by-13-by-10-inch dimensions suit compact gear, but not taller equipment.

Best for: Underbody and trailer storage.

Why it ranks #4: Built for underbody installation, it measures 30 × 14 × 16 inches and lists a rubber sealing strip, lock, two keys, and 66-pound maximum load.

A rubber sealing strip helps this 30-by-14-by-16-inch VEVOR box keep out water when closed, making it useful for storing tools or camping gear beneath a truck or trailer. Its underbody format also suits other locations, including a camper’s rear or a pickup rack, where accessible storage can free up space elsewhere.

The 0.06-inch-thick aluminum is listed as waterproof and resistant to rust and corrosion, supporting outdoor vehicle storage, while the rubber seal helps protect contents from water entering when the lid is closed. A lock and two included keys provide a way to secure stored equipment. At 30 by 14 by 16 inches, the box offers a defined underbody storage footprint, and its recommended maximum load is 66 pounds, a useful limit to keep in mind when packing heavier tools.

Skip it if you need to carry more than the listed 66-pound maximum; this box is intended for lighter loads.

Truck, trailer, or camper owners seeking lockable underbody storage for tools and camping equipment will appreciate its sealed aluminum construction. The 30-by-14-by-16-inch footprint and 66-pound maximum load are important boundaries when planning installation and packing.

Fully welded seams are intended to resist bending, shaking, weld cracking, and deformation during bumpy under-vehicle driving, supporting use where road vibration is a concern. The 36-by-17-by-18-inch interior gives substantial room for work or camping equipment, while the rubber seal and improved lid trough help keep out water and road debris. The aluminum box is lockable and can be removed and remounted, according to the supplied facts, for use across compatible vehicles.

Skip it if you prioritize the lightest possible box; this underbody model weighs 24.5 pounds.

Truck, RV, trailer, or ATV owners carrying tools through exposed or bumpy conditions can use its sealed, welded underbody storage. Its 36-by-17-by-18-inch size and 24.5-pound weight matter when planning clearance and handling.

7. FORWODE 20-Inch Toolbox

• Dimensions: 20"L x 12"W x 9.6"H
• Material: Aluminum

Best for: Compact pickup and garage storage.

Why it ranks #7: At 20 × 12 × 9.6 inches, this lockable aluminum box offers a compact option with two keys for smaller storage areas.

A 20-by-12-by-9.6-inch size makes this FORWODE box a compact choice for organizing tools in a pickup, RV, trailer, or garage. Its aluminum diamond plate has a powder-coated finish, combining a lightweight, corrosion-resistant construction with a lock and keys for securing the contents between uses.

The compact dimensions give this toolbox a smaller footprint than many full-length bed chests, which can suit owners with limited space or a short list of essential tools. Aluminum construction and the powder-coated finish are described as lightweight and rust-resistant, supporting portable use and outdoor storage. Heavy-duty hinges and stainless steel handles are listed features, and the lock with two keys adds security.

A gas-strut lid makes this 30-inch EASYBERG trailer tongue box easier to open while accessing tools, straps, and accessories. Its 30-by-13-by-13-inch aluminum body uses a five-bar tread pattern, combining a defined tongue-storage footprint with a surface and construction specified for corrosion resistance and outdoor durability.

Best for: Large trailer and RV storage.

Why it ranks #10: The 48.8 × 15.8 × 15.8-inch listing describes a general trailer-storage box, but gives less specific truck-bed fit information than the higher-ranked options.

A five-bar tread pattern strengthens the aluminum, while the lightweight construction is intended to limit added vehicle weight.
