1. UWS ECONO Series Crossover Tool Box: Best Overall
In our evaluation, the UWS ECONO Series stands out as the best overall sheep box for most truck owners. Its 22-gauge aluminum construction offers a great balance of weight and durability, and the diamond tread pattern adds traction and a classic look. The gas struts make the lid easy to lift, and the keyed-alike latches ensure all locks use the same key, simplifying access. Based on owner feedback, this box holds up well in typical use, though some long-term users mention the weather seals may need occasional replacement.
However, this box may not be the best choice for extreme off-road or heavy construction environments where maximum durability is critical. If you need a box that can withstand severe abuse, consider a thicker-gauge steel model. The UWS ECONO is ideal for daily drivers, weekend warriors, and light commercial use.
- Heavy-duty aluminum construction with diamond tread for strength and corrosion resistance
- Gas spring-assisted lid for easy opening and closing
- Keyed-alike rotary latches provide security and convenience
Pros: Excellent value for money with strong build quality; Easy to install with included hardware
Cons: Some users report minor gaps in weather sealing over time
2. DECKED Truck Tool Box: Best Modular System
The DECKED Truck Tool Box is a premium modular solution that impressed us with its rugged polyethylene construction. Unlike metal boxes, it will never rust or dent, and it integrates perfectly with the DECKED drawer system for organized storage. The lockable lid and weather-resistant seal keep contents dry and secure. Based on owner feedback, this box is nearly indestructible and holds up well in demanding conditions.
That said, the DECKED box comes at a premium cost. If you don’t need the modular drawer system or are on a tight budget, a simpler aluminum box may suffice. Also, the polyethylene material may feel less rigid than metal to some users. This box is best for professionals and serious overlanders who value durability and organization over cost.
- Rugged polyethylene construction resists dents, rust, and corrosion
- Integrates seamlessly with DECKED drawer system for modular storage
- Lockable lid with heavy-duty latches and weather-resistant seal
Pros: Extremely durable and weatherproof, no rust concerns; Versatile modular design allows customization
Cons: Higher price point compared to traditional aluminum boxes
3. Weather Guard Saddle Box: Best Heavy-Duty
For those who need the toughest box available, the Weather Guard Saddle Box is a top contender. Its 16-gauge steel body and continuous hinge provide exceptional strength, and the powder-coated finish holds up well against scratches and weather. The slam latch allows quick locking, which is convenient for frequent use. Based on owner feedback, this box is a workhorse that can handle heavy tools and rough jobsite conditions.
However, the steel construction makes it significantly heavier than aluminum alternatives, which can be a concern for payload capacity and fuel economy. If you need to maximize weight savings, an aluminum box is a better choice. This box is ideal for contractors and tradespeople who prioritize durability over weight.
- 16-gauge steel body with full-length continuous hinge for maximum strength
- Powder-coated finish resists scratches and corrosion
- Slam latch for quick locking without key
Pros: Extremely durable steel construction; Continuous hinge prevents lid sag
Cons: Heavier than aluminum boxes, may reduce payload
4. Rugged Ridge Crossover Tool Box: Best for Off-Road
The Rugged Ridge Crossover Tool Box is designed with off-road enthusiasts in mind. Its aluminum body is lightweight and resistant to corrosion, and the stainless steel latches and hinges hold up well in muddy or salty environments. The low-profile design does not obstruct rear visibility, a plus for off-road driving. Based on owner feedback, this box performs well on trails.
However, some owners have noted that the lid can become misaligned after repeated exposure to rough terrain. If you subject your truck to extreme off-road abuse, a more robust steel box may be necessary. This box is best for weekend off-roaders and overlanders who want a lightweight, corrosion-resistant option.
- Lightweight aluminum construction with black powder coat finish
- Stainless steel latches and hinges resist rust
- Low-profile design for better rear visibility
Pros: Corrosion-resistant hardware ideal for off-road conditions; Low profile maintains bed access and visibility
Cons: Some users report lid alignment issues after rough use
5. Buyers Products Aluminum Crossover Toolbox: Best Budget Pick
The Buyers Products Aluminum Crossover Toolbox is a solid entry-level option for truck owners on a budget. It provides basic weather protection and secure storage at a lower price point. The diamond tread aluminum is lightweight and corrosion-resistant, and the paddle latches are simple to use. Based on owner feedback, it works well for light-duty storage of tools and gear.
However, the thinner aluminum construction means it is more prone to dents and the latches may not last as long under heavy use. If you need a box for daily professional use or harsh conditions, we recommend spending more for a heavier-gauge model. This box is best for casual users who need affordable, basic storage.
- Affordable aluminum construction with diamond tread pattern
- Paddle latches for easy opening
- Weather-resistant rubber seal
Pros: Very budget-friendly without sacrificing basic functionality; Lightweight and easy to install
Cons: Thinner gauge aluminum may dent more easily; Latches feel less robust than premium models
6. Kobalt Crossover Truck Tool Box: Best for Security
The Kobalt Crossover Truck Tool Box focuses on security with its steel construction and reinforced lid. The locking T-handle and key lock offer peace of mind for storing valuable tools. The rubber weather seal helps keep out moisture. Based on owner feedback, this box is a decent choice for security-conscious buyers on a budget.
However, the steel body is heavy, and some users have complained about the latch being stiff or difficult to operate, especially in cold weather. The overall build quality is not as refined as premium brands. If security is your top priority and you can tolerate some inconvenience, this box may work. Otherwise, consider a higher-end model with better ease of use.
- Steel construction with reinforced lid for added security
- Locking T-handle with key lock
- Rubber weather seal
Pros: Reinforced lid and lock provide good theft deterrence; Powder-coated finish resists rust
Cons: Heavy and may reduce fuel economy; Some users report difficult latch operation
7. Truck Hero Crossover Tool Box: Best Lightweight
The Truck Hero Crossover Tool Box is designed for those who prioritize lightweight convenience. Its aluminum construction makes it one of the lightest options, and the gas struts provide smooth lid operation. The lockable design offers basic security. Based on owner feedback, this box is a good fit for light to moderate use where weight is a concern.
However, the thinner aluminum may not withstand heavy abuse, and some users have noted that the mounting brackets could be more robust. If you need a box for heavy tools or frequent rough use, a sturdier model is recommended. This box is best for daily commuters and light-duty users who want an easy-to-handle storage solution.
- Lightweight aluminum construction for easy handling
- Gas struts assist lid opening
- Lockable with included keys
Pros: Very lightweight, easy to install and remove; Gas struts work smoothly
Cons: Not as durable as heavier-gauge boxes; Some owners report minor fitment issues
Frequently Asked Questions
What is a sheep box for a truck?
A sheep box, also known as a truck tool box or crossover box, is a storage container that mounts across the truck bed behind the cab. It provides secure, weather-resistant storage for tools, equipment, and gear. The term “sheep box” is often used in Australia and New Zealand, but it refers to the same type of product.
How do I measure my truck bed for a sheep box?
To measure your truck bed, measure the width of the bed from inside wall to inside wall at the front near the cab. Also measure the depth (front to back) to ensure the box does not interfere with bed access. Most boxes are designed to fit standard truck bed widths, but it is important to check the manufacturer’s fitment specifications for your specific truck model.
Are sheep boxes weatherproof?
Most sheep boxes include weather seals around the lid to keep out rain and dust. However, no box is completely waterproof, especially if submerged. For better weather resistance, look for boxes with continuous hinges and high-quality rubber seals. Based on owner feedback, boxes with gas struts may allow some water ingress if the seals wear over time.
Can I install a sheep box myself?
Yes, most sheep boxes are designed for DIY installation. They typically come with mounting brackets and hardware that clamp onto the truck bed rails. Basic tools like a drill and socket set are usually required. Installation time ranges from 30 minutes to an hour. Some heavy steel boxes may require two people for safe lifting.
What is the best material for a sheep box?
The best material depends on your needs. Aluminum is lightweight, corrosion-resistant, and affordable, making it a popular choice for most users. Steel is stronger and more durable but heavier and prone to rust if the finish is damaged. Polyethylene (plastic) is rust-proof and dent-resistant but can be more expensive. Consider your priorities for weight, durability, and budget.

After researching and comparing the top sheep boxes for trucks, the UWS ECONO Series Crossover Tool Box earns our top pick for its excellent balance of durability, value, and ease of use.
