A vehicular support system is described and comprises a primary tube arrangement having a plurality of primary tubes arranged in a triangular pattern and adapted to run along at least one dimension of an associated vehicle. A plurality of secondary tubes are arranged in triangular patterns between said primary tubes, and at least some of said secondary tubes are coupled to two or more of said primary tubes and are arranged at an angle with respect to at least one of said two or more coupled primary tubes. One or more diaphragms are coupled to said primary tube arrangement and are adapted to deflect outward in response to a concentrated outside force incumbent thereupon. One or more bulkhead fittings are located at one or more distal ends of said primary tubes, and are adapted to couple the vehicular support system to a frame or chassis of said associated vehicle and to absorb stress in response to said concentrated outside force.
