This is a 1/64 22 Foot triple axle high side grain pup. The distance from the Ground to top of side wall is 51 millimeters. We also sell a low side grain pup, which has a height of 47 millimeters. A hitch for these trailers to hook onto is available. It mounts easily onto the bottom of the greenlight tandem, and should fit other trucks as well. Please note, this item is designed for display only and not for playing with; it contains small parts and could cause asphyxiation if swallowed or inhaled.
