Absolutely not a chance in hell.
Cold, lack of privacy, mooring costs (assuming you can get a decent one in the first place), depreciation, lack of space etc
I can't think of a single positive.
When DS was little one of his friends parents lived on one and we went for a few play dates.
It was fucking depressing. Cramped overall, no space to play, constantly having to keep your eye on the children for safety, cold as hell etc
I had to start making excuses as I just couldn't stand it (neither did DS like it).
The mother kept saying what a wonderful life it was and I thought at the time she was bonkers. Now I wonder if she was just trying to convince herself (it was a concept very much driven by her partner apparently who loved the freedom - but never did the trips to the laundry, supervised his son or cooked in the cramped kitchen
).
