A transportation trailer can include a cargo tank with a shell that includes an outer wall, an inner wall, and an insulating core between the outer wall and the inner wall. The shell can be unsupported by structural rings, and the cargo tank can be a frameless cargo tank. The cargo tank can be formed by decoiling respective coils of inner-wall material, outer-wall material, and insulating-core material, joining the inner-wall material, the insulating-core material, and the outer-wall material to form a sandwich-type panel, and welding the sandwich-type panel to form the shell.
