One couple with a semi trailer conversion has the entire back end covered with a video display - can swing to the side and entertain a gathering.
They also have a helipad.
did see another couple that replace their electric ZipDee with the manual version on an Airstream

I've had enough trouble with 50 year old technology. At least it's purpose built and not an amalgam of chassis and coach. I've seen those wiring diagrams.
