An improved means for providing overhead access to the freight compartment of a load carrying vehicle to facilitate loading and unloading of cargo. An elongate opening is defined in the roof of the compartment and includes a plurality of hinged door panels that provide a weathertight cover for the opening. Spanning the opening is at least one cross-brace which is rigidly tied to the roof at opposing edges of the opening so as to maintain the opening and afford stability to the opposing sidewalls. The cross-brace, which serves also to seat the door panels, is pivotally secured adjacent one edge about a horizontal axis, preferably at the opposing edge to that where the doors are hinged, such that the panels and cross-braces can be pivoted laterally away from the opening by an individual situated atop the van. When access is had, as in conventional vehicles, through an opening in the sidewalls, or endwall of the vehicle, the invention also contemplates including a movable header over the lower opening. The header, which otherwise divides the region between the overhead and lower openings, can be resituated to afford a continuous unrestricted region therebetween.
