Lunar Rover

How was this carried in the lunar lander?  It seems to be too big!

A great deal of money was spent on the lunar rover and a great number of problems had to be resolved before it could work on the moon's surface.  It wasn't a last minute addition deployed without any thought.

As with everything taken to the moon, weight and size were major considerations.   The Lunar Rover was designed to fold up and attach to the outside of the lunar lander.   So it didn't need to fit in the inside.  Once on the moon, it was deployed and automatically unfolded.
