A spaceframe for commercial vehicles is described. In embodiments, the spaceframe includes a body module and a cockpit module (incorporating a front module). In embodiments, the body module is divided into several modules such as a mid-module, a rear module, upper module, and a wheel arch module for modularity of the spaceframe.

A half-round cargo container comprises a plurality of curved panels and has a longitudinal axis. Each curved panel has a cross-sectional profile in a plane perpendicular to the longitudinal axis, wherein the respective cross-sectional profiles of the curved panels have curved shapes with a common curvature. Adjacent pairs of the curved panels are joined at respective abutting longitudinal edges parallel to the longitudinal axis to form a semi-cylindrical shell. The half-round cargo container has a top opening.

A quasi-cylindrical cargo container is formed of a plurality of rigid, curved panels together forming first and second semi-cylindrical shells, and a plurality of rigid, flat extension panels bridging the first and second semi-cylindrical shells. A method of manufacturing the container includes forming the first and second semi-cylindrical shell from the curved panels, forming the quasi-cylindrical shell from the first and second semi-cylindrical shells and the flat extension panels, forming collars conformably encompassing the quasi-cylindrical shell, constricting the collars to compress joints formed at abutting edges of pairs of adjacent panels, rolling the shell and collars sequentially to bring the joints to a lower position, welding inside seams of the joints when at the lower position, removing the collars, rolling the shell sequentially to bring the joints to an upper position, and welding outside seams of the joints when at the upper position.

Land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.
