Truck Tool Box Buying Guide

When using your truck for work, you will not want to leave tools on the back of the truck bed. Not only will they be loose and move around whilst driving but the tools will not be organized either. However, investing into a quality truck bed tool box will solve all your problems.

The main types of tool boxes for trucks include a crossover, side mount and chest. Each have their own benefits but its more important that they are compatible with your truck as some have different configurations. To help you make an informed buying decision, we have produced the below buying guide regarding truck tool boxes.

Truck Bed Tool Box

Types of Truck Bed Tool Boxes

There is a wide range of tool boxes for trucks available but choosing one that fits your requirements can be hard. Below are some details regarding each type to help you make up your mind.

Crossover Box

Crossover tool boxes are by far the most common and they mount against the back of the cab and sit on truck bed rails. Most will have a single lid that opens towards the window at the back but there are several variations, which feature double lids.

The main benefit is the fact they have a much larger capacity than all of the other different types. As they do not touch the bed of the truck, there is a space in between the bed and the tool box. This space is great for hauling goods that are long in length.

Chest Box

Instead of being mounted on the bed rails, the chest box sits on the bed of he truck. They are available in a range of different sizes and as they are not mounted on the bed rails, they will not effect any truck bed covers or canopies. However, when it comes to short trucks, the chest truck tool box may reduce much needed length.

Side Mount Box

Side mounted truck bed tool boxes are an excellent alternative that can be used alongside both the crossover and chest box. They can range in a variety of lengths but they are often not as wide, which can make storing some tools a struggle.

Other Types

Many tool box manufacturers are developing a range of clever designs to maximize truck bed space. Some do not even touch the bed of the truck and instead connect to the trailer hitch and even under the bed of the truck.

Crossover Truck Bed Tool Box

Cargo Capacity

The purpose of installing a truck bed tool box is to help store all your tools. However, if you cannot store all of them inside the box, it may become a problem.

We always recommended purchasing the largest cargo capacity that your truck is compatible with. It is always better to exceed the capacity that not having the space to store all of your tools in the box.

Durable Construction

The most common materials used within the construction of a tuck bed tool box are aluminum, stainless steel, plastic and steel. Aluminum is by far the most popular and for good reason too. It is strong, lightweight, resistant to rust and relatively affordable.

Choosing a tool box that is made completely from stainless steel will come with a much higher price tag. They are stronger than aluminum, rust resistant and generally looks and feels better than any other material.

Steel is the cheapest option and although it is a heavy duty material, it is not resistant to rust. If it has not been powder coated, it can begin to rust overtime, which can ruin the appearance of the box as the rust begins to spread. If it is not powder coated, we strongly recommend painting it yourself to improve its longevity.

Some smaller tool boxes that are used as a side mount or wheel well box are constructed of rugged plastic. They will not be able to withstand as much heavy impact damage but under light usage, they can be very long lasting.

Ease of Use and Convenience

What makes the difference between a good and an excellent tool box is how easy they are to use. When you are holding all of your tools, opening or closing the box needs to be convenient. Some features that would be desirable include:

  • Limited force to open or close the lid
  • Smooth operating lock
  • Easy to install and remove for portability
  • Low profile design to reduce obstruction of rear view visibility
  • Trays, holders and compartments for organization

Intuitive design features can make all the difference when compared to a tool box that is just a storage container.

Security Features

Considering that the tool box is storing your valuables, it is important that it is kept secure. Most come with basic locks but premium truck bed tool boxes come with extra special locks that are more secure. The materials used in the construction also need to be strong because cheap plastic or metals can easily break with heavy impacts.

Another factor that many people forget is the way the truck tool box is mounting upon the bed. If it is not mounting properly using the correct hardware, it may be possible to manually pull the tool box out.


When it comes to deciding on the type of truck bed tool box you want, it is vital that you take measurement beforehand. You will want to measure the width as well as the height of the box. Some tool boxes may reduce rear view visibility quite significantly, which can be big issues for some people.

All of our recommendations cover a wide variety of tool boxes as well as budgets. Investing a little extra into a durable tool box for your truck is highly advised as it will be long lasting and be able to withstand more punishment from heavy usage.
