Obviously, the above commenter just needs an actual supercarrier... Which is to say, an F-150 with a generator is about as big of a base of operations you can get that mostly fits in a parking spot.

If I'm taking a mobile home or... that thing... somewhere, it's generally a planned event. Whereas my "mobile base of operations" should be something that's always with me during my day-to-day, but also has a significant amount of resources I might need.
