A method of attaching an element to the inner surface of a rotationally molded structure, comprising: connecting said element to one end of an elongated heat conductive member; attached said heat conductive member to a mold for producing said structure such that said element is spaced from said mold

A method of attaching an element to the inner surface of a rotationally molded structure, comprising: connecting said element to one end of an elongated heat conductive member; attached said heat conductive member to a mold for producing said structure such that said element is spaced from said mold by a distance sufficient to permit mold material to flow between said element and said mold; rotationally molding said structure by heating said mold, filling said mold with mold material, and rotating said mold, whereby heat from said mold is transferred through said heat conductive member to said element and causes said mold material to melt around and adhere to said element when taking the shape of said mold; removing said member from said molded structure by cutting a portion out of said molded structure around said member and disconnecting said element from said heat conductive member.
