A body structure for a customized van is enhanced by providing a roof support element which is light in weight, strong, and easily shaped to conform to curved roof lines. The body structure comprises a rafter having upper and lower extruded rails and a plurality of gussets connected between the rails to join the rails in a single member. The rails are T-shaped in cross section with the upright of the T providing a point for connection of the gussets.
