Really enjoyed seeing all these videos, and great to have them all in one post.
Fascinating to see such problem-solving ingenuity!
I particularly liked RealKerbal3x, GewoonLukas_, Aotezukay, Robossbomb, KSPotato, but all are interesting and inspiring.
My own version of a Duna rover mission, done long after the event, and obviously without the time deadline, tries to remain both Kerbal and close to the real thing using stock parts only.
It's a 12-minute video. I hope someone enjoys it.
