trailer
Let an agent explain what a trailer is, relay its kinds, coupling and regulation from reference sources, describe the kinds its aliases name, and distinguish a trailer from a powered vehicle and from a semi-trailer.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.
