The outer skin of our command communications trailer body is a 0.125 inch aluminum sheet for maximum strength and resistance to damage from normal use. The 0.125 inch outer skin is bonded to the welded structural frame using a method of attachment, which yields a clean exterior surface. NO rivets are utilized to attach the outer skin of the command communications trailer to the structural frame. The structural frame is reinforced where necessary by welding in aluminum plates, tubes and sections. All door frames are welded into the structural frame of the command communications trailer.
