|size

|
|Interior dimensions (cargo area) of the body in meters. (width, height, length)
|-
|total_size
|float3
|
|Overall exterior dimensions of the trailer in meters. (width, height, length)
|-
|volume
|float
|
|The cargo volume in meters cubed (m<sup>3</sup>).
|-

|Path to the detailed mesh model descriptor (.pmd). This is used only for vehicles used by player. Additionally they are used in vehicle previews & browser windows.
|-
|model

|Path to the model descriptor (.pmd). If only a single LOD is used, it should be set up as '''model''', and the other attributes (detail_model, lods) should not be defined. Presently it is typical to use only this for owned trailers.
|-
|lods
|array<string>
|
|Paths to the reduced level-of-detail model descriptors (.pmd), in order of increasing viewing distance (decreasing model complexity).
|-
|collision
|string
|
|Path to the collision descriptor (.pmc).
|-
|variant
|token
|
|Variant to be used from '''detail_model''', '''model''', and '''lods'''.
|-
