An unnamed box trailer is due to appear in Grand Theft Auto VI, spotted in the very first scene of the first trailer wearing a Patriot Beer livery behind a Phantom Custom. It resembles GTA V's ramp-door trailer but is taller and wider, swapping the swing-down ramp for two conventional rear doors.
First trailer appearance
At 0:03 in the first Grand Theft Auto VI trailer, the box trailer appears in the opening scene. It carries Patriot Beer branding and is attached to a Phantom Custom. This is the only specified GTA VI sighting: no other screenshots, promotional appearances, locations, or users are identified.
It is classified as a tractortrailer with the body type Tractor Trailer. No price, manufacturer, selectable variant, modification, handling information, or gameplay role has been shown.
Rear-door design comparison
Its design is compared with Grand Theft Auto V’s ramp-door trailer. The GTA VI trailer has a greater height and width than the standard box trailer, while using a pair of ordinary doors at the rear rather than the GTA V ramp-door trailer’s drop-down rear ramp.
No earlier-series history beyond that GTA V comparison is established. The available footage confirms the exterior configuration, but does not show the trailer’s interior, cargo capacity, detachment behaviour, or any mechanical quirks.
