This is beautiful! I did a much, much smaller one in KSP1, but it was just a Minmus lander- it definitely could not have escaped Kerbin atmo! I love doing sci-fi replicas. I'm glad to see KSP2 opens new possibilities there.
Edit:
PS Also, I live in a motorhome full-time, and am an RV enthusiast, so your Eagle 5 appeals to me there as well.
