Choosing the right truck tool box can improve storage efficiency, protect valuable equipment, and make daily work easier.
However, different toolbox designs solve different problems.
A pickup truck owner may need quick access and large storage capacity. A service vehicle operator may need organized storage without losing cargo space. A flatbed truck user may need additional storage under the vehicle.
The three most common designs are:
-
Crossover truck tool box
-
Side mount truck tool box
-
Underbody truck tool box
Each option has different advantages.
This guide explains the differences between these toolbox types and helps buyers choose the right solution for their vehicles and applications.
What Are the Main Types of Truck Tool Boxes?

The best choice depends on:

Vehicle structure
-
Available installation space
-
Tool access frequency
-
Working environment
-
Storage capacity requirements
Before purchasing, buyers should understand how each toolbox design works.

Crossover Truck Tool Box: Large Storage for Pickup Trucks
A crossover truck tool box is installed across the truck bed, usually behind the cab.
This design is one of the most popular storage solutions for pickup trucks because it provides a large storage area while keeping tools easy to access.
Crossover tool boxes are commonly used by:
-
Contractors
-
Mechanics
-
Builders
-
Maintenance workers
Advantages of Crossover Truck Tool Boxes
A crossover design provides:
-
Large internal storage space
-
Easy access from both sides of the truck
-
Secure tool protection
-
Efficient use of truck bed space
For buyers looking for a practical pickup storage solution, LANSHUO provides durable aluminum options such as the:

The aluminum construction provides lightweight performance while maintaining durability for outdoor and commercial applications.
Side Mount Truck Tool Box: Fast Access for Professional Work
A side mount truck tool box is installed along the side of the vehicle.
This design is ideal for users who need frequent access to tools during daily work.
Common applications include:
-
Service trucks
-
Repair vehicles
-
Electrical vehicles
-
Plumbing vehicles
Advantages of Side Mount Tool Boxes
Side mount designs help users:

Underbody Truck Tool Box: Maximize Storage Without Losing Truck Bed Space
An underbody truck tool box is designed for users who need additional storage while keeping the main truck bed available for cargo.
Unlike crossover tool boxes that sit above the truck bed, underbody models install below the vehicle frame.
This makes them especially useful for:
- Flatbed trucks
- Service trucks
- Utility vehicles
- Commercial vehicles
- Work trailers
Advantages of Underbody Tool Boxes
Underbody storage solutions provide several benefits:
- Save valuable truck bed space

For professional vehicles, storage space is often limited.
An underbody design allows workers to carry more equipment without reducing the loading area.
LANSHUO provides durable solutions such as:
48 Inch Heavy Duty Underbody Aluminum Tool Box
This type of aluminum storage box is suitable for customers who need reliable protection for tools in outdoor and commercial environments.
