Containers!

ISO Containers expands base-building possibilities in Project Zomboid by introducing industrial shipping containers and large fuel storage tanks.

Designed for survivors who need more space for equipment, furniture and vehicle parts, the modification provides practical storage structures that can be transported and incorporated into a permanent base.

The 2026 update, celebrating five years of the project, completely overhauls the original containers and introduces smaller variants and wheels.

Shipping Containers for Your Base

Large industrial containers are ideal for organizing valuable supplies and storing bulky equipment.

They can be used for:

• Storing vehicle parts and mechanical supplies.
• Keeping unused furniture and equipment.
• Organizing large quantities of materials.
• Creating dedicated storage areas around a survivor base.

The containers also feature animated doors and removable objects, making them more interactive than ordinary decorative structures.

Where Can You Find Containers?

New structures spawn naturally throughout the game world.

Exploring industrial areas and fuel facilities provides opportunities to obtain these useful structures.

Industrial Fuel Tanks

ISO Containers also introduces large fuel tanks with the functionality of a gas tanker trailer.

These tanks allow players to maintain substantial fuel reserves at their base, reducing the need for frequent trips to gas stations.

They are especially useful for long-term survival setups with generators and multiple vehicles.

Build 41 requirement: Fuel storage functionality requires Tsar's Common Library.

Towing and Transportation

Shipping containers and fuel tanks can be towed using vehicles.

However, they are extremely heavy and slow to transport.

Unlike ordinary trailers, these structures are primarily intended for stationary storage rather than routine cargo transportation.

Important Towing Advice

• Use a sufficiently powerful vehicle.
• Expect slow towing speeds.
• Avoid loading containers with large amounts of cargo before transporting them.
• Do not treat them like standard road trailers.
• Avoid attempting to tow heavy containers with underpowered cars such as the Dart.

The safest approach is to transport the container to your base first, then fill it with supplies.

2026 Overhaul

The anniversary update modernizes the original modification with several improvements.

Highlights include:

• Completely overhauled container models and functionality.
• New smaller shipping container variants.
• Added wheels for improved practical use.
• Updated storage structures.
• Existing animated door functionality.

The containers cannot be recolored.

Compatibility and Installation

Adding to an Existing Save

ISO Containers can be enabled during an ongoing playthrough.

Open the save selection menu, choose the existing world and enable the modification before loading.

The game will then be able to use the added container types.

Vehicle Identifiers

For server administrators and players working with vehicle spawn configurations, the modification includes the following identifiers.

Current vehicle IDs:

TrailerISOcontainerM1
TrailerISOcontainerM2
TrailerISOcontainerM3tanker
TrailerISOcontainerM4damaged
TrailerISOcontainerS2

Legacy identifiers are also present for compatibility with earlier versions.

ISO Containers is a useful addition for players who enjoy constructing large, organized survivor bases. Whether you need a place for spare vehicle parts or an industrial tank for fuel reserves, these structures provide practical long-term storage options while fitting naturally into Project Zomboid's post-apocalyptic environment.
