Plastic Tool Box for Pickup Truck

Pickup truck tool boxes come in pretty handy for organizing small items like tools, so it’s always good to have one mounted in your truck bed. A majority of the boxes are quite sturdy since they are made from metals such as stainless steel and  aluminum. However, they tend to be pricey; therefore, a plastic storage box is an excellent option since it’s both practical and affordable.

A plastic tool box for a pickup truck should be strong, durable, sizeable, and made from a sturdy, heavy-duty plastic material. It should be secure, compatible with canopies, weatherproof, versatile, and provide easy access to the tool box contents.

The DU-HA 70200 Humpstor Truck Bed Storage Unit  

The DU-HA 70200 Humpstor Truck Bed storage unit is quite unique. While it resembles a side-mounted tool box, it usually fits beneath your truck’s bed rails and the usually wasted space atop your wheel wells. This feature makes the tool box excellent for use alongside a tonneau cover or even a canopy since both typically lie above the bed rails. They can thus cover up the storage box with ease. 

This plastic tool box boasts a sturdy build as it’s made using superior grade, durable plastic. Although thick-walled, this material is light in weight and only weighs 26 pounds (1.79kg). Besides, the thick walls make it difficult for thieves to cut their way into the tool box. Though it doesn’t come with a lock, it sports latches on either end plus one in the middle. You can therefore use up to 3 padlocks to keep the tool box secure.

The plastic tool box is quick and easy to install. This is because it comes with a pair of mounting brackets that you attach to the bottom of the bed rail. Furthermore, you can adjust the brackets to suit your height. Installation only takes a couple of minutes, although it might take you a bit longer to achieve the exact height you desire. 

Another great thing about this plastic tool chest is that it provides additional storage space if you use a canopy without losing valuable floor space. You see, the DU-HA Humpster truck bed tool box has 4 movable inner walls. And, you can use these walls to create separate compartments, which makes you better organized. 

What’s more, given the lockable latches, you can choose to use the storage unit as a single compartment for a legal gun case. It can comfortably fit a rifle with a scope attached or two shotguns and would make an excellent addition to your hunting kit. Additionally, it includes an organizer or gun rack set.

It’s important to note that this plastic storage box won’t work if you don’t cut the liner, thus if your truck has a drop-in bed liner, it’s best to consider another course of action. The DU-HA 70200 tool box measures 55 inches (139.7 cm) long and has a width and depth of under 10 inches (25.4 cm), (55 x 9.75 x 10 inches). This allows it to fit well when placed above the pick up wheel and under the bed rail. The tool box fits in most standard-size trucks too.

Still, if you own either a mid-size or compact pickup truck, it’s good to confirm the measurements to ensure the DU-HA will be a good fit.


  • It is affordable.
  • It boasts sturdy plastic construction.
  • It comes with a Lifetime Warranty.
  • It’s easy to install using accompanying brackets. 
  • It comes with lockable latches to protect contents from theft.
  • It can act as a legal gun case and holds a rifle fitted with a scope or 2 shotguns.
  • It offers extra truck-bed storage without taking up valuable bed floor space.
  • It fits well under tonneau covers, toppers, canopies, and roll-up covers.


No Weatherproofing Strip

One notable downside of the DU-HA plastic tool box is that it does not contain a weatherproofing strip through the lid or body. As a result, during a heavy downpour, some water might seep inside. However, this would not be an issue of concern if a tonneau cover is used instead. As such, it’s advisable to lay down some adhesive automotive strips or adhesive rubber strips to form a watertight seal.

The DU-HA is Rather Small

This plastic tool box comes at a great bargain but is relatively small compared to metal tool boxes. Again, if you own a drop-in bed liner, you will not only need to cut out sections to make it fit, but you can only mount it to your bed at the designated points on the box. The DU-HA is, therefore, more ideal for small or mid-size pickup trucks. If you have a full-size pickup truck, you might need to buy another DU-HA to mount on the other bed rail. 

VDP 31300 Wheel Well Storage Unit

The VDP Wheel Well plastic truck tool box fits between your truck’s tailgate and wheel well. This wheel-well style tool box is convenient because it uses up the space above your wheel wells that tends to stay unutilized. The tool chest features two compartments providing excellent space to store your tools well-organized.

Made from thick, heavy-duty plastic, the VDP Wheel Well plastic truck tool box is hard, strong, and durable. It also boasts a reversible lid making it ideal for use on whichever side of the pickup truck bed you choose. And given that the tool box is rather small, you may decide to buy a pair for each of your wheel wells to get maximum storage. 

The plastic tool boxes come in 2 two sizes; one for full-size trucks and another for midsize trucks It also comes equipped with all you need to mount it to your pickup truck. Despite lacking a rubber strip, both the tool box’s lid as well as the body fit jointly using a groove that helps prevent water or dust from getting in.

In any case, attaching weather stripping could make the tool box more difficult to close given its design though you risk taking in some water after a long period out  in either snowy or rainy weather.

This plastic truck bed tool box makes a great tailgating or camping companion. Its larger compartment provides the perfect ice container, while the smaller container keeps essential items, like your wallet, phone, and sunglasses, safe and dry. Besides, the speaker offers decent sound quality and comes with a 25 feet (7.62m) speaker wire enabling you to connect the speakers to your stereo. Finally, 4 cup holders embedded atop the lid hold your drinks steady.

One drawback to using the VDP plastic tool box is a likelihood that rainwater might pool on the lock since it’s located at the top of the lid. With time, this could lead to rusting. To prevent this from happening, you may want to mount locks on either side instead and lock the tool box from here.

BAK BAKBox 2 Fold-Away Utility Box

The BAK BAKBox 2 Fold-Away Utility Box is another distinctive plastic pickup storage box that’s  ideal for use alongside your tonneau cover. However, the BAKBox2 tool box is lidless thus it relies on the panels of your watertight BakFlip Tonneau Cover to protect your stored items from the elements. Thus, to keep your tools or storage contents safe and well-protected, consider using the tool box along with a canopy or tonneau cover. 

Like other BAKFlip truck bed covers, the BAKBox2 doesn’t stick out over your truck rails but lies completely flush. This provides you with a clean, stylish look. Manufactured in the USA, this plastic tool box is guaranteed to last as long as your pickup truck.

Constructed with robust FRP composite panels – these resist impact much better than even  aluminum according to BAK-, the tough plastic tool box won’t break easily. However, you might want to ensure that it will fit well in your pickup truck’s bed before purchasing one. 

This tool box has a length measuring 65 inches (165.1cm) which therefore means the tool box will fit a 65-inch wide truck bed such as that one of a Chevrolet Silverado or GMC Sierra. So, if you own a different pickup truck model, make sure to measure the truck’s bed properly so as to ensure a proper fit.

Since the BAKBox 2 doesn’t come with a lid, it only becomes secure and safe from the elements if you use a lockable and watertight tonneau cover. As such, if you plan on keeping  valuables in your plastic tool box, you’d better have the tonneau cover. If not, then use it for storying things like groceries. 

This plastic storage box mounts with remarkable ease underneath your pickup truck’s bed rails using the thoughtfully-included brackets. The best part is it doesn’t require any drilling. It also comes with a small sliding tray that you can use to separate the storage space into smaller compartments and store small-sized items. 

What’s more, when unused, the BAKBox 2 folds up, providing additional inches of bed space. This also helps protect it when you choose to use the bed to haul materials or large loads.

While the BAKBox 2 is a rather small tool box, it still provides more space than either the DU-HA or the VDP plastic tool boxes. Before making an order, it’s crucial to bear in mind that the tonneau cover is not included in the BAKBox 2 purchase.

Undercover SwingCase Storage Box 

The innovative SwingCase is a small, hard-sided plastic storage tool box attached to your truck bed’s side. It has a hinged mount that allows it to swing out almost 180° over the open tailgate, granting you easy access. The tool box helps keep your often-used gear organized, plus you don’t need to climb into the truck bed to access it. According to the manufacturer, the SwingCase’s mount can support a weight of up to 75 pounds ( 34kg).

This side-mounted versatile truck storage box is long-lasting. It’s built using light in weight, high-impact, ABS plastic making SwingCase tough, weather-resistant, and custom-made to fit your pickup truck. It also has a seal in place to keep your contents dry and moisture-free. The tool box allows full use of your truck bed and swings out your gear to you without using any tools. Remarkably, the SwingCase even stands on its own.

The great thing about this tool box is that it doesn’t hamper your ability to load large loads between the wheel wells since it stows behind them. Also, the design ensures that it doesn’t get in your tonneau cover’s way. And, if your pickup truck has no tonneau cover, the SwingCase locks in place with a lockable, weathertight lid. 

The UnderCover SwingCase is a truck bed cover compatible and maintains a 3-inch (7.6 cm) clearance from the truck bed. It works with almost all tonneau covers, including hard, soft, folding, and rolling tonneaus. And the best part? Undercover SwingCase has the backing of a 1-year guarantee and a US-based customer support team, making this plastic pickup tool box the ultimate premium storage solution.

Easy to install, the Undercover SwingCase measures16 x 8.5 x 34 inches (40.6 x 21.5 x 86.3 cm) and comes with 6 self-tapping screws to help secure the mount to your pickup truck. It fits snugly into the sidewall, and an arch over the rear wheel ensures that the tool box does not extend into your pickup’s bed space. This means that you still have ample space to haul more cargo or equipment.

When you need to carry your tools or other cargo along with you, all you need to do is simply lift the SwingCase off its hinged bracket. This plastic tool box fits the 2020 – 2021 Chevrolet Silverado or GMC Sierra HD 2500 and 3500. Watch this video featuring the Undercover SwingCase plastic storage box on Amazon for more details.
