You might see this as a lame Autobot, but it's the only Transformer I'd have any actual use for:
Adapt-X is the name of a utility trailer, that transforms into…a compact box. This allows you to store it in a space much smaller than its in-use footprint.
The trailers are made primarily from aluminum, with stainless steel hardware and a steel axle. They come in multiple sizes, ranging from 4x8 to 6x12, with cargo capacities ranging from 2,122 lbs to 2,312 lbs.
These are produced by Canadian company Apogee Trailers, and run roughly $4,500 to $6,500.
