How to spawn complete trucks on a DayZ server

By Niko Catarino

Updated 3 October 2026

To equip newly spawned vanilla trucks, configure their attachments in a spawnabletypes XML file and register it in the active mission’s cfgeconomycore.xml. This controls how the Central Economy equips new vehicles. It does not increase the truck population, choose spawn locations or retrofit vehicles already saved in your world.

The procedure below uses a specific creator-maintained package for covered trucks, with fuel containers and repair items in cargo. It covers DayZ PC mission-file access, including transfers through VXPanel.

Choose the truck and check the source version

Scalespeeder’s complete-truck tutorial was published on 27 April 2026. Its linked fuel and tyre-repair package includes separate files for three vanilla classes:

Truck class	Package filename
Truck_01_Covered	Veh-Truck_01_Covered-complete-empty-cfgspawnabletypes.xml
Truck_01_Covered_Blue	Veh-Truck_01_Covered_Blue_Covered-complete-empty-cfgspawnabletypes.xml
Truck_01_Covered_Orange	Veh-Truck_01_Covered_Orange_Covered-complete-empty-cfgspawnabletypes.xml

Scroll to see all columns →

Keep the filenames exactly as supplied, including the repeated Covered in the colored variants. Choose only the variants you intend to change.

The package README records limited testing on PC Chernarus, DayZ 1.29, April 2026. That is the creator’s test scope. Compare the file with your installed build and map before applying it to a live world; a recent upload does not establish compatibility with every later release.

Understand what the override replaces

Bohemia’s mission-file modding reference allows separately registered spawnable-type files. Defining attachments for a class replaces its original attachment list; defining cargo replaces its original cargo list.

Preserve the complete attachment list: An override containing only a battery can replace the other configured attachments. Review the full desired list for that class before registering the file, including any existing custom cargo or attachments you want to retain.

The reviewed Truck_01_Covered file requests these attachment groups:

Attachment	Groups in the file
Truck_01_Wheel	4
Truck_01_WheelDouble	4
TruckBattery	1
HeadlightH7	2
Hood and left/right doors	1 each

Scroll to see all columns →

The attachment groups and their items use chance="1.00". These counts describe XML groups, not a claim about the number of usable wheel positions on the vehicle. Check the spawned truck’s actual attachments in game.

The cargo requests two CanisterGasoline items, one TireRepairKit and one LugWrench. Fuel containers in cargo do not prove that the truck’s fuel tank is full or that the containers contain a specific quantity. The file requests a damage range of 0.1–0.2; it does not promise pristine vehicles.

For another vehicle model or a Workshop vehicle, use that model’s valid classnames and attachment requirements rather than copying this truck’s parts list.

Back up the active mission

Confirm the active mission from the server configuration. For Chernarus, a common PC path is mpmissions/dayzOffline.chernarusplus; other maps and custom missions use different directories.

Stop the server, verify your backup inclusions, and save the active mission, persistence and relevant mod-owned data. Make the XML edits on a working copy. Existing world vehicles do not need to be wiped for this configuration change.

Search the active mission’s registered files for the selected truck class. If another file already overrides it, decide which definition should supply its attachments and cargo before uploading another one.

Register one truck file

Start with Truck_01_Covered on a test mission:

1. Download its complete XML file from the linked package and read it in a text editor.
2. Create custom inside the working mission if it does not already exist.
3. Put Veh-Truck_01_Covered-complete-empty-cfgspawnabletypes.xml in that folder.
4. In cfgeconomycore.xml, add this registration inside the existing <economycore> element, before its closing tag:

<ce folder="custom">
    <file name="Veh-Truck_01_Covered-complete-empty-cfgspawnabletypes.xml" type="spawnabletypes" />
</ce>

5. Retain the mission’s existing defaults, classes and registrations. If a <ce folder="custom"> block already exists, add the file entry to it instead of replacing its other entries.
6. Parse both complete XML files, then upload the edited core file and chosen truck file while DayZ is stopped. With VYKIX, use Files and SFTP.

Run this syntax check from the root of the downloaded working mission in PowerShell:

[xml](Get-Content -LiteralPath '.\custom\Veh-Truck_01_Covered-complete-empty-cfgspawnabletypes.xml' -Raw) | Out-Null
[xml](Get-Content -LiteralPath '.\cfgeconomycore.xml' -Raw) | Out-Null

Use cfgeconomycore.xml, not cfgeconomy.xml. The registration type is spawnabletypes, not types. Parsing checks syntax; the startup and gameplay checks below establish whether the intended file and class are used.

Check a new natural spawn

Start the test server and inspect its new RPT and script logs. Resolve missing-file, XML or classname errors before checking vehicles.

Find a truck newly created by the Central Economy after the change. A persisted truck can keep its previous state. A vehicle spawned manually through an admin tool can also use that tool’s own attachment options, so it is a separate test.

Check:

• The selected truck class and its fitted wheels, battery, lights, hood and doors.
• The requested cargo and its actual condition and quantities.
• The vehicle’s fuel and other required fluids, usable attachments and ability to start and drive.
• Other vehicle classes and existing persistent vehicles, to catch changes outside your intended scope.

If existing trucks already occupy the event’s target population, a new one may not appear immediately. Observe normal replacement or use a separate test world. Do not delete the live world’s vehicle persistence just to speed up this check.

Diagnose an incomplete truck

Symptom	Check
Newly spawned trucks look unchanged	Confirm the active mission, deployed file, exact filename, registration type and competing overrides.
Only a colored truck is unchanged	Confirm that its own class file was uploaded and registered.
Some attachments disappeared	Review the complete replacement attachment list and valid item classnames.
Truck has parts but will not drive	Inspect wheel usability, battery condition, required fluids and any vehicle mod’s behavior.
Old trucks remain incomplete	Test a new economy spawn; this edit does not retrofit persisted vehicles.
No additional trucks appear	This package does not change the vehicle event population or locations.

Keep population and location changes as separate tasks. They involve the corresponding event configuration and spawn positions, and need their own balance and persistence review.

Roll back and retain the test result

Record the build, map, package revision, truck class and observed attachments, cargo and fluids. Keep the tested XML with the mission backup so the next update has a comparison point.

To roll back, stop the server and remove only this file’s registration, or restore the saved core file without discarding unrelated later edits. Restart and check the logs. Trucks already created under the override remain part of the world until normal persistence and cleanup behavior changes their state.

For other economy changes, use the loot tutorial and infected spawn tutorial. Follow the server update guide when replacing stock mission files.
