Our Popular Tool Box Styles for Trucks

With so many options on the market, it's essential to find a tool box that fits both your truck and your workflow. Each type offers unique benefits, from low-profile truck tool box designs to spacious chest-style options. Here's a closer look at the most popular styles.

The crossover tool box spans the width of your pickup's bed, sitting atop the bed rails to provide maximum storage space. Most also sit above the bed floor, letting you load oversized cargo like boards, pipes, and plywood without limiting bed length. For a traditional look and maximum utility, a crossover tool box, like the Dee Zee Red Label Single Lid crossover tool box, is tough to beat.

Like to keep the entire length of your bed open for oversized cargo? Consider a side-mount tool box, such as the UWS Side Mount truck tool box. These convenient boxes mount on your bed rail for easy access from outside the bed, opening outward so you can reach your tools, valuables, or other cargo without ever climbing in.

Ideal for the truck enthusiast who doesn't love the look of a tool box but wants the functionality. Tool chests, like the UWS Truck Bed Utility Chest, typically sit below the bed rails, disappearing into the bed for a sleek appearance. They feature one large lid at the top for easy access to everything inside. If you frequently need tools without climbing into the bed, plenty of other styles offer easier access from outside.

Take control of your pickup's unused space with a wheel well tool box, like the RealTruck UnderCover Swing Case. These innovative boxes mount in the space between your wheel well and tailgate, retaining nearly 100 percent of your cargo area while giving you secure, organized storage.

Take your storage into the job site with a portable tool box, like the DU-HA Squad Box. Most portable boxes include a mounting base to secure them in the bed while driving, plus integrated wheels and a pull strap for easy transport once you've arrived.

Don't want a truck tool box organizer taking up space in your bed? Mount it on your trailer's tongue instead. Trailer tongue tool boxes, like the UWS Trailer Tongue Box, feature a tapered shape that narrows toward the front, following your trailer's tongue for tight-turn clearance while still offering plenty of cargo space.​

Our Best-Selling Truck Tool Box Materials and Finishes

Once you've found the right style, the next step is choosing the best material for your needs. Tool box construction plays a significant role in durability, weight, and weather resistance, so it's worth knowing what each option brings to the table.

Lightweight, corrosion-resistant, and durable, aluminum is a solid choice for anyone who wants strength without adding unnecessary weight. Most aluminum truck chest tool box options are manufactured from diamond plate material, which adds rigidity while allowing for a thinner, lighter-gauge metal. Aluminum tool boxes typically come in black powder coat and polished finishes.

Steel is another commonly used alloy, known for its remarkable strength and durability. Unlike aluminum, though, steel is heavier and prone to corrosion if not properly coated. That's why steel tool boxes are generally powder-coated or painted to prevent oxidation. Steel holds up best in industrial applications, where a little extra weight and surface wear aren't a dealbreaker.

Generally constructed from ABS, polyethylene, or PP, composite tool boxes are tough and fully corrosion-resistant. They resist dents and dings, and they're lightweight and easy to install. Most composite materials, however, aren't quite as durable as their alloy counterparts.​

Why Choose RealTruck's Truck Tool Boxes?

The RealTruck SwingCase is one of the most distinctive products in this category because RealTruck actually manufactures it. Unlike crossover or chest boxes that eat into bed rail or bed floor space, the SwingCase mounts in the wheel well and swings open on a gas-assisted lid, giving you secure, lockable storage without taking over the rest of the bed. Buying SwingCase from RealTruck means buying direct from the manufacturer, with full warranty support and no distributor markup.​

We're also one of the few retailers to curate a dedicated collection of tool box-compatible truck bed covers. If you want both a cover and a box, you don't have to guess or dig through spec sheets. Our tool box tonneau cover category shows exactly what's verified to work together, cutting out one of the top return reasons in both categories.​

Fitment errors are the number-one complaint shoppers raise about truck bed tool boxes, so we built our Guaranteed Fit program to eliminate that risk. Any eligible product that doesn't bolt up to your specified vehicle within 30 days ships back free of charge, with no restocking fee. In a category where a two-inch bed width mismatch can mean a full return, that guarantee is what lets you order with confidence.​

Q: How Do I Know The Tool Box Will Fit In My Truck Bed Without Moving Around?

A: When shopping for a truck tool box, it's essential to select an option compatible with your specific bed dimensions. Measure your truck's bed width, length, and inner rail spacing, and confirm the tool box matches before ordering. For help, check out our guide on how to measure your truck bed.​

Q: Is Steel Or Aluminum Better For Truck Tool Boxes?

A: Both materials have their pros and cons. Steel is exceptionally durable and rigid, though it's prone to corrosion and relatively heavy. Aluminum is lightweight and naturally corrosion-resistant, though it's not quite as rigid as steel. In most cases, either material will serve you well.​

Q: What Is The Best Brand Of Tool Box?

A: At RealTruck, we carry tool boxes from several notable manufacturers. Some of our favorites include UnderCover, UWS, and WeatherGuard.​

Q: What Is The Difference Between A Crossover, Chest, Side Mount, And Wheel Well Tool Box?

A: Crossover boxes span the full bed width just behind the cab and sit on top of the bed rails, the highest-capacity option with the most visible profile. Chest boxes sit on the bed floor below the rail line, making them compatible with most truck bed covers and nearly invisible from outside. Side-mount boxes run parallel to one or both bedsides, ideal for daily work-truck use without climbing into the bed, and wheel-well boxes tuck into the wheel-well area to preserve the rest of the bed for cargo.​

Q: Will A Truck Tool Box Work With My Tonneau Cover?

A: It depends on the style. Standard crossover boxes that sit on the bed rails will block most soft or hard roll-up covers from closing fully, while low profile crossover boxes and chest boxes that sit below the rail are compatible with select covers. RealTruck maintains a curated category of covers verified to work with a bed-mounted box.​

Q: Are Truck Tool Boxes Actually Waterproof?

A: Most quality truck tool boxes are weather-resistant, not fully waterproof. Weather-resistant means the seal keeps out rain, splash, and light moisture in normal conditions, while true submersion-level waterproofing isn't a standard claim in this category. Closed-cell foam seals and continuously welded seams consistently outperform thin rubber gaskets that compress and gap over time, and draining lid channels help divert water away from the seal before it can pool.​

Q: How Does RealTruck's Guaranteed Fit Program Work For Tool Boxes?

A: RealTruck's Guaranteed Fit program covers eligible tool box products that don't install correctly on the vehicle specified at the time of order, within 30 days of delivery. If the box doesn't fit as specified, we cover the return freight at no charge and don't apply a restocking fee.
