1. Dee Zee DZ8500 Heavy Duty Diamond Tread Tool Box: Best Heavy-Duty Crossover Box
In our evaluation, the Dee Zee DZ8500 stands out for its robust build quality and long-term durability. Made from thick aluminum diamond plate, this crossover tool box resists dents, rust, and UV damage. Owner feedback consistently praises its ability to withstand heavy use and harsh weather. The gas spring props allow one-handed operation, and the paddle latches provide secure closure. However, the box’s weight (over 50 pounds) can be a drawback for those who frequently need to maximize payload. If you prioritize durability over weight savings, this is a top choice.
This box is best for truck owners who need a rugged, long-lasting storage solution for heavy tools and equipment. Those with lighter needs or who frequently remove their toolbox may want to consider a lighter aluminum model. The DZ8500 is not ideal for compact trucks where it may limit bed space significantly.
- Heavy-duty aluminum construction with diamond tread for strength and corrosion resistance
- Crossover design provides full-width access to truck bed
- Includes stainless steel paddle latches and gas spring props for easy opening
Pros: Extremely durable and weather-resistant; Secure locking system with paddle latches
Cons: Heavy weight can reduce payload capacity
2. UWS TBX-12-56 Low Profile Crossover Tool Box: Best Low-Profile Crossover
We researched the UWS TBX-12-56 and found it excels for drivers who want a toolbox without sacrificing rear visibility. Its low-profile design sits just above the bed rails, allowing full use of the bed for larger items. The Brite-Tread aluminum is highly resistant to corrosion, and owner feedback indicates the finish holds up well over years. The rotary latches are smooth and secure. However, the reduced height limits storage for tall items like shovels or long tool handles. If you primarily store small parts and hand tools, this is an excellent choice.
This box is ideal for truck owners who need a balance of storage and bed accessibility. It may not suit those who require deep storage for bulky equipment. For full-size trucks, the 56-inch length may leave gaps on each side; check fitment carefully.
- Low-profile design preserves rear visibility and truck bed access
- Brite-Tread aluminum finish resists corrosion
- Stainless steel rotary latches with lockable T-handle
Pros: Low profile improves visibility and aerodynamics; Easy to install with quick-mount brackets
Cons: Less interior space than full-height boxes
3. Weather Guard 126-5-01 Steel Crossover Tool Box: Most Secure Steel Box
Based on owner feedback and the spec sheets, the Weather Guard 126-5-01 is among the most secure tool boxes available. Its heavy-gauge steel construction and powder-coat finish provide excellent resistance to theft and corrosion. The recessed paddle latches are designed to prevent prying, and the gas struts support the heavy lid. However, the steel box weighs over 60 pounds, which can be a concern for payload and fuel economy. Installers report it requires two people to mount safely. If security is your top priority, this box delivers.
This box is best for contractors storing expensive tools in high-theft areas. It is not recommended for those who need frequent access to the truck bed or who prioritize weight savings. The steel construction may also dent if struck hard, though it is generally robust.
- Heavy-gauge steel with powder-coat finish for maximum security and durability
- Recessed paddle latches with lockable handles
- Full-length lid opening with gas struts
Pros: Extremely secure; resists forced entry; Very durable and long-lasting
Cons: Very heavy; reduces payload significantly
4. Rugged Ridge 18003.10 Black Aluminum Cargo Box: Best for Off-Road Use
We evaluated the Rugged Ridge 18003.10 as a versatile cargo box for off-road enthusiasts. Its aluminum construction keeps weight low, and the compact size allows it to be mounted in various positions without occupying the entire bed. Owner feedback from off-road forums highlights its durability on rough trails, but many note that the lid seal is not fully waterproof. In heavy rain or pressure washing, moisture can seep inside. For dry storage of recovery gear and tools, it performs well. However, sensitive items require additional dry bags.
This box is ideal for Jeep truck and mid-size pickup owners who need a rugged, lightweight storage solution for off-road gear. It is not suitable for those requiring waterproof storage or large capacity. The latch mechanism is adequate but may be less secure than paddle-latch designs.
- Lightweight aluminum construction with black powder-coat finish
- Lockable latch with key and hasp for padlock
- Mounting brackets included for bed or roll bar attachment
Pros: Lightweight and easy to install; Compact size fits in smaller beds or leaves room for other gear
Cons: Not weather-sealed; water can enter under heavy rain
5. Buyers Products BX100-40 Aluminum Underbody Box: Best Underbody Storage
Based on our research, the Buyers Products BX100-40 is a practical solution for those who want to maximize bed space. By mounting under the truck bed, it keeps tools accessible without cluttering the bed. The aluminum construction is corrosion-resistant, and the weather seal helps keep contents dry. However, installation is more involved than a crossover box, often requiring drilling into the frame. Owner feedback indicates that access can be awkward, especially if the truck is lifted or has aftermarket bumpers. The capacity is limited to smaller items like straps, blocks, and small tool sets.
This box is best for truck owners who frequently use the entire bed for hauling and need out-of-the-way storage. It is not recommended for those who want quick, easy access to tools or who are not comfortable with drilling into their vehicle. The box may also reduce ground clearance, so it is not ideal for off-road use.
- Underbody mounting saves bed space
- Durable aluminum with powder-coat finish
- Lockable latch with weather-resistant seal
Pros: Frees up bed space for other cargo; Good corrosion resistance
Cons: Installation requires drilling and may be complex; Limited capacity; not for large tools
6. Plano 1919 Gun Guard Truck Box: Best for Firearm Storage
In our evaluation, the Plano 1919 Gun Guard Truck Box is purpose-built for transporting firearms and sensitive gear. The foam lining cushions contents, and the dual-lock system adds security. However, the polyethylene construction, while lightweight and weather-resistant, is less secure than steel or thick aluminum. Owner reviews report that the latches can be vulnerable to forced entry. Additionally, the foam can trap moisture if the box is not dried properly, potentially causing rust on metal items. For general tool storage, it lacks the durability of metal boxes.
This box is best for hunters and shooters who need a dedicated, padded case for firearms in their truck. It is not recommended for high-security tool storage or for harsh environments where the plastic may become brittle over time. The box is also somewhat bulky for its capacity.
- Foam-lined interior protects firearms and valuables
- Keyed lock and padlock hasp for dual security
- Lightweight and weather-resistant polyethylene
Pros: Excellent protection for delicate items; Lightweight and easy to move
Cons: Not as secure as metal boxes; can be pried open; Foam lining may retain moisture
7. Delta 40-5000 Polyethylene Cargo Box: Budget-Friendly Cargo Box
Based on aggregated owner feedback, the Delta 40-5000 offers good value for those on a budget. Its large capacity and UV-stabilized polyethylene make it suitable for general cargo storage. However, the lid latch is a simple snap-tab that does not accept a padlock, offering little security. Some owners report cracking after prolonged exposure to extreme temperatures. The box is best for storing lightweight, non-valuable items like camping gear or sports equipment. It is not designed for heavy tools or secure storage.
This box is ideal for casual users who need an inexpensive, lightweight storage solution for occasional use. It is not recommended for contractors, security-conscious owners, or those in very cold climates. The box may also warp under heavy loads if overfilled.
- Affordable polyethylene construction with UV protection
- Large capacity for its price point
- Removable lid with integrated handles
Pros: Very affordable compared to metal boxes; Lightweight and easy to install
Cons: Lid latch is not lockable; security is minimal; Not as durable; can crack in extreme cold
Frequently Asked Questions
What is the most secure type of truck box?
Based on our research, steel tool boxes with recessed paddle latches and lockable handles offer the highest security. The Weather Guard 126-5-01 is a prime example, with heavy-gauge steel and a powder-coat finish that resists prying. Aluminum boxes with rotary latches are also secure, but steel provides the best theft deterrence.
How do I choose the right size truck box?
Measure your truck bed width and depth between the wheel wells. Crossover boxes typically range from 48 to 72 inches. For full-size trucks, a 60-inch box is common. Also consider the box height relative to your bed rails: low-profile boxes preserve visibility, while full-height boxes offer more storage. Check manufacturer fitment guides for your specific truck model.
Are aluminum truck boxes better than steel?
Aluminum boxes are lighter, resist rust better, and are easier to install. Steel boxes are stronger and more secure but heavier and prone to rust if the finish is damaged. Your choice depends on priorities: aluminum for weight savings and corrosion resistance, steel for maximum security and durability.
Can I install a truck box myself?
Most crossover boxes come with J-bolts and mounting brackets for DIY installation. Basic tools like a wrench and drill are usually required. Underbody boxes require drilling into the frame and may need professional installation. Always follow the manufacturer’s instructions and ensure the box is securely fastened to prevent movement during driving.
How do I maintain my truck box?
For aluminum boxes, wash with mild soap and water to remove road salt and grime. Apply a protective wax or sealant annually. For steel boxes, inspect for scratches and touch up with matching paint to prevent rust. Lubricate latches and hinges with silicone spray. Check seals regularly to ensure they remain watertight.
