Addon: Peterbilt Survival Truck

Author: Rifk1
Peterbilt Survival Truck adds a large working truck that is built piece by piece instead of appearing as a finished vehicle. Its components behave like placeable blocks, and sixteen dye colors allow the cab and equipment to match a chosen design.

All required parts have survival recipes. The assembly system guides the player through attaching the components, after which the completed vehicle can be driven across the world.

A cargo cage turns the truck into an animal and mob carrier. Install it with the wrench, then lead a creature to the vehicle or interact with a leashed mob to load it. The current carrying system accepts a wide range of entities.
The suspension visually follows steep terrain and full-block steps. The latest version also refines carrying behavior so loading is more reliable and less demanding on weaker devices.

Color changes and separate construction stages also make the vehicle useful as a garage project or fleet centerpiece, not only as transport.
How to install the add-on
Download the .mcaddon or .mcpack file, open it with Minecraft and wait for the import to finish. Then enable the resource and behavior packs in the world settings. If the add-on requires experiments, turn them on before launching the world.
