The LEGO City Off-Road 4x4 Mountain Truck is a 221-piece building set designed for children aged 6 and up. Kids can assemble a rugged off-road truck featuring functional details like a working winch for steep inclines, a flip-up snorkel that reveals the hood, and roof storage boxes for tools and gear. The set includes an adventurer minifigure along with accessories such as a camera, water bottle, flashlight, map, compass, binoculars, tools, and a first-aid kit for imaginative play. When built, the truck measures over 3 inches (7 cm) high, 5.5 inches (13 cm) long, and 2.5 inches (6 cm) wide. The LEGO Builder app provides digital building instructions with 3D model viewing and progress tracking. This set serves as a standalone playset or a gift option for young builders.
