    Why doesn't the rear frame of the trailer flex on flat ground?

    Taking the doors off saves weight and complexity.

    I know that nobody has answered the question yet because the answers thus far are just begging the question.

    Why does the rear frame of the trailer twist on sloped ground but not on flat ground? Because sloped ground cause the rear frame of the trailer to twist but flat ground does not cause the rear frame of the trailer to twist.

    The assembly line is flat when it is built.
    So that makes me all line up and square to itself.
    Slopes twist even the frame underneath some, but the top of the trailer wants to tip further aka gravity.

    The rear frame of the trailer does flex on flat ground relative to the position of the rear frame of the trailer while not on flat ground.

    The baseline of the relationship between the doors and the frame is that of flat ground because that is the condition it was manufactured in.

    If it was manufactured on ground that was not flat then the doors would be manufactured to fit the structure that resulted from that practice.

    Flat ground is the starting condition for many man made structures similar to how the number zero is the starting condition for many systems of measurement so much so that it is an assumed starting condition.

    I don't see why the force of gravity would be stronger at the top of the trailer than at the bottom of the trailer. So your answer does not make sense to me.

    All the answers I have received so far have been wholly unsatisfactory.
