Basecamp is retained as an evidence-limited NHTSA-derived make because its admitted record pairs the make name with Portland Vintage. That combination points to a recreational or camping-trailer identity, but the available registry row does not establish whether Basecamp was a manufacturer, a product family, a conversion business or a dealer-facing brand. Separate public businesses use Basecamp as a model name—including Airstream's Basecamp travel trailer and Portland-area van or trailer conversion operations—so those unrelated identities are not merged into this record. The catalog keeps Basecamp discoverable, treats Portland Vintage as the only admitted model label, and avoids assigning a founding year, factory, chassis, production total or relationship to Airstream without a direct type-approval or manufacturer source.
