<p>A load body is provided defining at least one upstanding wall construction, including laterally spaced upstanding structural members spaced therealong and upper and lower downwardly and upwardly facing surfaces extending along upper and lower marginal portions of the one wall construction. Each pair of adjacent structural members includes adjacent marginal portions defining outwardly facing abutment and seal surfaces extending therealong and outwardly facing abutment surface portions spaced therealong, each spaced at least slightly from the corresponding abutment and seal surface toward the adjacent structural member. A removable upstanding body closure panel is provided for mounting between each pair of adjacent structural members and includes opposite upstanding side marginal edge portions extending therealong having inner side surfaces abutted against the abutment surface portions and elongated seals extending along and projecting edgewise outwardly therefrom for overlapped engagement with the corresponding pair of abutment and seal surfaces. Further, structure is carried by each of the structural members operative to releasably engage and apply a yieldable inward force on each adjacent closure panel marginal edge portion.</p> |
