I notice that L79's placement of the joints of diagonals to uprights is somewhat above and below the intersection of the uprights' joints with the longitudinal tubes, rather than forming the apexes of two triangles between two uprights. I could see how this placement could make the joints more easily weldable to the novice welder, which I am certainly one, without the difficulties of getting into "tight crotches", so to speak. With respect to my question and your reply above, could this placement afford deflection/distortion potential in the event of an impact that would be possibly beneficial to whatever soft tissue might be onboard, and would this represent best practice, or acceptable practice?
