Abstract: The present disclosure concerns a vehicle. The vehicle comprises a structural frame having a longitudinal axis and comprising a roof structure, a floor structure vertically spaced apart from the roof structure, first and second sidewalls extending substantially parallel to the longitudinal axis, between the roof structure and the floor structure and being transversally spaced apart from one another. Each of the first and second sidewalls has an upper edge region mechanically connected to the roof structure and a lower edge region supported by the floor structure. At least the first sidewall comprises at least one structural frame member extending substantially diagonally between the upper edge region and the lower edge region of the first sidewall. The vehicle further comprises an energy supply support mounted to and supported by the roof structure.
