It is purely “art”. Totally non-functional. No guy wires, unstable in the slightest wind.
I bet they put it up for fast photos and take it down quickly, lest the wind pick up.
Yup, as a ham my first thought was “It needs guy wires...lots of guy wires.”
You could drive in long stakes at an angle around the camper to anchor the guys and then raise the camper and tighten the wires up with some sort of 12v power winches.
Sure wouldn’t want that wake up call when the wind picked up at night...
