I recommend the seventh video, (with the purple overlay lines).

In it he shows that the dimensions of the lunar rover and a Vietname era Jeep are very very close.

Boeing charged $39,000,999 to construct a special extra-lightweight aluminum state of the art machine. Yet the rear panel where the astronauts tools were hung is the exact size of a jeep tailgate, frame and bumpers very close to exactly the same dimensions.

Is this just a coincidence?

Or did Boeing take a Jeep and make a few thousand dollars of modifications to the frame and new tires and put some car batteries and an electric motor on that sucker and charged $39,000,000?
