Abstract: Embodiments herein provide methods, apparatuses, and systems for fastening articles to an internal, or free form, surface of a rotomolded base. Inserts of various shapes and sizes may be incorporated/molded into a rotomolded base to provide a conventional primary attachment site on the exterior surface of the base. A portion of an insert that is molded into the base may project from the interior surface of the base. The projecting portion of the insert and the overlying rotomolded material may form a coupling element on the interior surface of the base, which may be used to attach an article to the interior surface.
