Many of the surface images of the LM, show it tilted one way or another. Landing on NOT A LEVEL surface and the inherent ability to remain upright without toppling over as JayUtah has descirbied as with A15
Would the original large lander needed for direct ascent or EOR been able to land at that angle without tipping over?
Since the
final configuration, not the artist conceptions, isn't known, a conclusion might be very difficult to derive. As Jay has indicated the center of gravity of the body
probably would have been higher and thus the vehicle would have been more prone to tipping over.
