A universal chassis frame is disclosed having a ladder-frame construction that is configurable to position the rear axle(s) at variable set of preset distances from the back of the cab of the vehicle to provide for customized rail/bed lengths over a range of medium/heavy classes of electric trucks. In various embodiments, the chassis frame includes a central frame having a pair of main frame rails configured to support at least two battery modules substantially within an intra-frame space defined between the pair of main frame rails. A front subframe is configured to support a cab, the front portion including a pair of upper frame members mounted above the corresponding pair of the main frame rails, and a front axle unit mounted under the front subframe. A rear subframe is configured to support at least one rear axle unit mounted under the rear subframe and any of a set of multiple configurable rear payload units via a common connection interface affixable to the main frame rails such that the location of the rear subframe with respect to the main frame is longitudinally variable at different sets of predetermined distances from the back of the cab.
